Update to 2.15.0.

- Remove NetBSD support, its completely bitrotted
- Suggest to set DEVELOPER=yes in /etc/make.conf if committer flag specified in command line
- Fix WARN: Makefile: [11]: possible direct use of command "libtool" found...
- Small fixes:
  * 'WWW: UR:' -> 'WWW: URL'
  * @option_helpers -> remove leading '_' use _$m instead
  * fix a few 'undefined variable' warnings
- Make MAN{X} checks NO_STAGE only (consolidate/simplify check)
- Make some checks in checkplist NO_STAGE only
- Convert PERL_CONFIGURE check to USE_PERL5=configure
- Make "use .if ${PORT_OPTIONS:MDOCS} to wrap installation of files into
  $localbase/share/doc" warning NO_STAGE only
- Add special case for global options(DOCS/EXAMPLES/NLS/IPV6) in
  OPTIONS_DEFINE, but not in PORT_OPTIONS:M$i
- Check for relative path (/../) in *DEPENDS
- Remove MASTER_SITES that don't resolve or returns 5xx
- Remove LINTSKIP check that was commented since 1997
