Portability fixes.

tell Cygwin and Haiku to pkglint.
Import user-20130306 as sysutils/user_cygwin.

This implements a subset of useradd(8)/groupadd(8) functionality on
Cygwin that is sufficient for pkgsrc use.
Added sysutils/user_cygwin version 20130306
+ user_cygwin
Switch to use own user_cygwin for _USER_DEPENDS.

Note update of TYPO3 packages:

	www/typo3_45 	4.5.24
	www/typo3_46 	4.6.17
	www/typo3_47 	4.7.9
Version 1.7.52 (built with libpng-1.6.1beta06 and zlib-1.2.7)
  Added license info for cexcept.h, libpng, and zlib.
  Added consideration of "zopfli" compression to the "To do" list.
  Fixed a typo that caused a cHRM chunk to be "found" if an iCCP chunk
    were present.
  Reset best_byte_count before trial loop.
  Revise global png_set_keep_unknown_chunks() calls to avoid a libpng16
    warning.
  Reset "intent" to "specified_intent" before trial loop.
  Reset "plte_len" to "specified_plte_len" before trial loop.
  Initialize length of each trial to 0x7fffffff so any untried method
    is not the "best method".
Updated graphics/pngcrush to 1.7.52
Add SunOS support.
Add SunOS support.
pbulk: do not recursively restrict packages.
Set license to
  mit AND 2-clause-bsd AND isc AND modified-bsd
because that's what the included LICENSE file says, after one wdiffs
the MIT license and the first part.  (There does not appear to be such
a thing, as a "joyent license", which is good news.)
It turns out there wasn't a specific joyent license; libuv is MIT
(following Node.js) with a few included BSD/ISC libraries.  So this is
no longer needed.
Patch from upstream for potential buffer overflow reading the certificate
index file (Changeset 6298:c7eff98bb299, see mutt flea #3636).
From upstream: replace undefined use of sscanf() in reading from POP
server with simple parsing.
