r290232:
Microoptimize.
r290231:
Addition to prev. commit.
In some edge cases fp->_p can be changed in _sseek(), recalculate.
r290230:
Don't seek to the end if write buffer is empty (in append modes).
PR: 204156
r290110:
Add _flags2 per jhb@ suggestion since no room left in _flags.
Rewrite O_APPEND flag checking using new __S2OAP flag.
r289931:
According to POSIX, a write operation shall start at the current size of
the stream (if mode had 'a' as the first character).
r289863:
Since no room left in the _flags, reuse __SALC for O_APPEND.
It helps to remove _fcntl() call from _ftello() and optimize seek position
calculation in _swrite().

MFC r266971:
- Return NULL and set errno to EINVAL if size is 0 (as required by POSIX).
Update the manpage to reflect this change.
- Always set the current position to the first null-byte when opening in append
mode. This makes the implementation compatible with glibc's. Update the test
suite.

- Correct size and position variables type from long to size_t.
- Do not set errno to ENOMEM on malloc failure, as malloc already does so.
- Implement the concept of "buffer data length", which mandates what SEEK_END
refers to and the allowed extent for a read.
- Use NULL as read-callback if the buffer is opened in write-only mode.
Conversely, use NULL as write-callback when opened in read-only mode.
- Implement the handling of the ``b'' character in the mode argument. A binary
buffer differs from a text buffer (default mode if ``b'' is omitted) in that
NULL bytes are never appended to writes and that the "buffer data length"
equals to the size of the buffer.
- Remove shall from the man page. Use indicative instead. Also, specify that
the ``b'' flag does not conform with POSIX but is supported by glibc.
- Update the regression test so that the ``b'' functionality and the "buffer
data length" concepts are tested.
- Minor style(9) corrections.
