o Move NTOHL() and associated macros into <sys/param.h>. These are

  deprecated in favor of the POSIX-defined lowercase variants.
o Change all occurrences of NTOHL() and associated marcros in the
  source tree to use the lowercase function variants.
o Add missing license bits to sparc64's <machine/endian.h>.
  Approved by: jake
o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
  POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
  and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
  complexities associated with having MD (asm and inline) versions, and
  having to prevent exposure of these functions in other headers that
  happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
  third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.
