Add the BSD-licensed Citrus iconv to the base system with default off
setting. It can be built by setting the WITH_ICONV knob. While this knob is unset, the library part, the binaries, the header file and the metadata files will not be built or installed so it makes no impact on the system if left turned off. This work is based on the iconv implementation in NetBSD but a great number of improvements and feature additions have been included: - Some utilities have been added. There is a conversion table generator, which can compare conversion tables to reference data generated by GNU libiconv. This helps ensuring conversion compatibility. - UTF-16 surrogate support and some endianness issues have been fixed. - The rather chaotic Makefiles to build metadata have been refactored and cleaned up, now it is easy to read and it is also easier to add support for new encodings. - A bunch of new encodings and encoding aliases have been added. - Support for 1->2, 1->3 and 1->4 mappings, which is needed for transliterating with flying accents as GNU does, like "u. - Lots of warnings have been fixed, the major part of the code is now WARNS=6 clean. - New section 1 and section 5 manual pages have been added. - Some GNU-specific calls have been implemented: iconvlist(), iconvctl(), iconv_canonicalize(), iconv_open_into() - Support for GNU's //IGNORE suffix has been added. - The "-" argument for stdin is now recognized in iconv(1) as per POSIX. - The Big5 conversion module has been fixed. - The iconv.h header files is supposed to be compatible with the GNU version, i.e. sources should build with base iconv.h and GNU libiconv. It also includes a macro magic to deal with the char ** and const char ** incompatibility. - GNU compatibility: "" or "char" means the current local encoding in use - Various cleanups and style(9) fixes.

+.Os
+.Sh NAME
+.Nm __iconv_get_list
+.Nm __iconv_free_list
+.Nd retrieving a list of character encodings supported by
+.Xr iconv 3
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In iconv.h
+.Ft int
+.Fn __iconv_get_list "char ***names" "size_t count" "bool paired"
+.Ft void
+.Fn __iconv_free_list "char **names" "size_t count"
+.Sh DESCRIPTION
+The
+.Fn __iconv_get_list
+function obtains a list of character encodings that are supported by the
+.Xr iconv 3
+call.
+The list of the encoding names will be stored in
+.Fa names
+and the number of the entries is stored in
+.Fa count .
+If the
+.Fa paired
+variable is true, the list will be arranged into
+canonical/alias name pairs.
+.Pp
+The
+.Fn __iconv_free_list
+function is to free the allocated memory during the call of
+.Fn __iconv_get_list .
+.Sh RETURN VALUES
+Upon successful completion
+.Fn __iconv_get_list
+returns 0 and set the
+.Fa names
+and
+.Fa count
+arguments.
+Otherwise, \-1 is returned and errno is set to indicate the error.
+.Sh SEE ALSO
+.Xr iconv 3 ,
+.Xr iconvlist 3
+.Sh STANDARDS
+The
+.Nm __iconv_get_list
+and
+.Nm __iconv_free_list
+functions are non-standard interfaces, which appeared in
+the implementation of the Citrus Project.
+The iconv implementation of the Citrus Project was adopted in
+.Fx 9 .

+.In iconv.h

+.Sh DESCRIPTION
+The
+.Fn iconv_open
+function opens a converter from the codeset
+.Fa srcname
+to the codeset
+.Fa dstname
+and returns its descriptor.
+The arguments
+.Fa srcname
+and
+.Fa dstname
+accept "" and "char", which refer to the current locale encoding.
+.Pp
+The
+.Fn iconv_open_into
+creates a conversion descriptor on a preallocated space.
+The
+.Ft iconv_allocation_t
+is used as a spaceholder type when allocating such space.
+The
+.Fa dstname
+and
+.Fa srcname
+arguments are the same as in the case of
+.Fn iconv_open .
+The
+.Fa ptr
+argument is a pointer of
+.Ft iconv_allocation_t
+to the preallocated space.
+.Pp
+The
+.Fn iconv_close
+function closes the specified converter
+.Fa cd .
+.Pp
+The
+.Fn iconv
+function converts the string in the buffer
+.Fa *src
+of length
+.Fa *srcleft
+bytes and stores the converted string in the buffer
+.Fa *dst
+of size
+.Fa *dstleft
+bytes.
+After calling
+.Fn iconv ,
+the values pointed to by
+.Fa src ,
+.Fa srcleft ,
+.Fa dst ,
+and
+.Fa dstleft
+are updated as follows:
+.Bl -tag -width 01234567
+.It *src
+Pointer to the byte just after the last character fetched.
+.It *srcleft
+Number of remaining bytes in the source buffer.
+.It *dst
+Pointer to the byte just after the last character stored.
+.It *dstleft
+Number of remainder bytes in the destination buffer.
+.El
+.Pp
+If the string pointed to by
+.Fa *src
+contains a byte sequence which is not a valid character in the source
+codeset, the conversion stops just after the last successful conversion.
+If the output buffer is too small to store the converted
+character, the conversion also stops in the same way.
+In these cases, the values pointed to by
+.Fa src ,
+.Fa srcleft ,
+.Fa dst ,
+and
+.Fa dstleft
+are updated to the state just after the last successful conversion.
+.Pp
+If the string pointed to by
+.Fa *src
+contains a character which is valid under the source codeset but
+can not be converted to the destination codeset,
+the character is replaced by an
+.Dq invalid character
+which depends on the destination codeset, e.g.,
+.Sq \&? ,
+and the conversion is continued.
+.Fn iconv
+returns the number of such
+.Dq invalid conversions .
+.Pp
+There are two special cases of
+.Fn iconv :
+.Bl -tag -width 0123
+.It "src == NULL || *src == NULL"
+If the source and/or destination codesets are stateful,
+.Fn iconv
+places these into their initial state.
+.Pp
+If both
+.Fa dst
+and
+.Fa *dst
+are
+.No non- Ns Dv NULL ,
+.Fn iconv
+stores the shift sequence for the destination switching to the initial state
+in the buffer pointed to by
+.Fa *dst .
+The buffer size is specified by the value pointed to by
+.Fa dstleft
+as above.
+.Fn iconv
+will fail if the buffer is too small to store the shift sequence.
+.Pp
+On the other hand,
+.Fa dst
+or
+.Fa *dst
+may be
+.Dv NULL .
+In this case, the shift sequence for the destination switching
+to the initial state is discarded.
+.Pp
+.El
+The
+.Fn __iconv
+function works just like
+.Fn iconv
+but if
+.Fn iconv
+fails, the invalid character count is lost there.
+This is a not bug rather a limitation of
+.St -p1003.1-2008 ,
+so
+.Fn __iconv
+is provided as an alternative but non-standard interface.
+It also has a flags argument, where currently the following
+flags can be passed:
+.Bl -tag -width 0123
+.It __ICONV_F_HIDE_INVALID
+Skip invalid characters, instead of returning with an error.
+.El
+.Sh RETURN VALUES
+Upon successful completion of
+.Fn iconv_open ,
+it returns a conversion descriptor.
+Otherwise,
+.Fn iconv_open
+returns (iconv_t)\-1 and sets errno to indicate the error.
+.Pp
+Upon successful completion of
+.Fn iconv_open_into ,
+it returns 0.
+Otherwise,
+.Fn iconv_open_into
+returns \-1, and sets errno to indicate the error.
+.Pp
+Upon successful completion of
+.Fn iconv_close ,
+it returns 0.
+Otherwise,
+.Fn iconv_close
+returns \-1 and sets errno to indicate the error.
+.Pp
+Upon successful completion of
+.Fn iconv ,
+it returns the number of
+.Dq invalid
+conversions.
+Otherwise,
+.Fn iconv
+returns (size_t)\-1 and sets errno to indicate the error.
+.Sh ERRORS
+The
+.Fn iconv_open
+function may cause an error in the following cases:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+Memory is exhausted.
+.It Bq Er EINVAL
+There is no converter specified by
+.Fa srcname
+and
+.Fa dstname .
+.El
+The
+.Fn iconv_open_into
+function may cause an error in the following cases:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+There is no converter specified by
+.Fa srcname
+and
+.Fa dstname .
+.El
+.Pp
+The
+.Fn iconv_close
+function may cause an error in the following case:
+.Bl -tag -width Er
+.It Bq Er EBADF
+The conversion descriptor specified by
+.Fa cd
+is invalid.
+.El
+.Pp
+The
+.Fn iconv
+function may cause an error in the following cases:
+.Bl -tag -width Er
+.It Bq Er EBADF
+The conversion descriptor specified by
+.Fa cd
+is invalid.
+.It Bq Er EILSEQ
+The string pointed to by
+.Fa *src
+contains a byte sequence which does not describe a valid character of
+the source codeset.
+.It Bq Er E2BIG
+The output buffer pointed to by
+.Fa *dst
+is too small to store the result string.
+.It Bq Er EINVAL
+The string pointed to by
+.Fa *src
+terminates with an incomplete character or shift sequence.

+.Sh STANDARDS
+The
+.Fn iconv_open ,
+.Fn iconv_close ,
+and
+.Fn iconv
+functions conform to
+.St -p1003.1-2008 .
+.Pp
+The
+.Fn iconv_open_into
+function is a GNU-specific extension and it is not part of any standard,
+thus its use may break portability.
+The
+.Fn __iconv
+function is an own extension and it is not part of any standard,
+thus its use may break portability.

+.Xr iconv 3
+.Sh LIBRARY
+.Lb libc
+.Sh SYNOPSIS
+.In iconv.h
+.Ft int
+.Fn iconvctl "iconv_t cd" "int request" "void *argument"
+.Sh DESCRIPTION
+The
+.Fn iconvctl
+function can retrieve or set specific conversion
+setting from the
+.Fa cd
+conversion descriptor.
+The
+.Fa request
+parameter specifies the operation to accomplish and
+.Fa argument
+is an operation-specific argument.
+.Pp
+The possible operations are the following:
+.Bl -tag -width -indent
+.It ICONV_TRIVIALP
+In this case
+.Fa argument
+is an
+.Ft int *
+variable, which is set to 1 if the encoding is trivial one, i.e.
+the input and output encodings are the same.
+Otherwise, the variable will be 0.
+.It ICONV_GET_TRANSLITERATE
+Determines if transliteration is enabled.
+The answer is stored in
+.Fa argument ,
+which is of
+.Ft int * .
+It will be set to 1 if this feature is enabled or set to 0 otherwise.
+.It ICONV_SET_TRANSLITERATE
+Enables transliteration if
+.Fa argument ,
+which is of
+.Ft int *
+set to 1 or disables it if
+.Fa argument
+is set to 0.
+.It ICONV_GET_DISCARD_ILSEQ
+Determines if illegal sequences are discarded or not.
+The answer is stored in
+.Fa argument ,
+which is of
+.Ft int * .
+It will be set to 1 if this feature is enabled or set to 0 otherwise.
+.It ICONV_SET_DISCARD_ILSEQ
+Sets whether illegal sequences are discarded or not.
+.Fa argument ,
+which is of
+.Ft int *
+set to 1 or disables it if
+.Fa argument
+is set to 0.
+.It ICONV_SET_HOOKS
+Sets callback functions, which will be called back after successful
+conversions.
+The callback functions are stored in a
+.Ft struct iconv_hooks
+variable, which is passed to
+.Nm
+via
+.Fa argument
+by its address.
+.\" XXX: fallbacks are unimplemented and trying to set them will always
+.\" return EOPNOTSUPP but definitions are provided for source-level
+.\" compatibility.
+.\".It ICONV_SET_FALLBACKS
+.\"Sets callback functions, which will be called back after failed
+.\"conversions.
+.\"The callback functions are stored in a
+.\".Ft struct iconv_fallbacks
+.\"variable, which is passed to
+.\".Nm
+.\"via
+.\".Fa argument
+.\"by its address.
+.Sh RETURN VALUES
+Upon successful completion
+.Fn iconvctl ,
+returns 0.
+Otherwise, \-1 is returned and errno is set to
+specify the kind of error.
+.Sh ERRORS
+The
+.Fn iconvctl
+function may cause an error in the following cases:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+Unknown or unimplemented operation.
+.It Bq Er EBADF
+The conversion descriptor specified by
+.Fa cd
+is invalid.
+.Sh SEE ALSO
+.Xr iconv 1 ,
+.Xr iconv 3
+.Sh STANDARDS
+The
+.Nm
+facility is a non-standard extension, which appeared in
+the GNU implementation and was adopted in
+.Fx 9
+for compatibility's sake.
+.Sh BUGS
+Transliteration is enabled in this implementation by default, so it
+is impossible by design to turn it off.
+Accordingly, trying to turn it off will always fail and \-1 will be
+returned.
+Getting the transliteration state will always succeed and indicate
+that it is turned on, though.
