Bump PKGREVISION for libXft changes for NetBSD native X support on
NetBSD 6, requested by tron.
Remove libjpeg-turbo option.

* libjpeg-turbo support is obsolete by patch-image_decoders_nsJPEGDecoder.cpp.
Bump PKGREVISION from firefox/mozilla-commom.mk's change.
Note revbump of firefox and seamonkey.
Change the way we fix up $rm_try to avoid a tools directory reference.

Fixes errors seen on SmartOS with PKG_DEVELOPER=yes when the fixed file was
regenerated after the fixup, and appears to have the added benefit of removing
the warnings about out of date builds during install.
Drop maintainership.

I'm not particularly paying attention to gitweb.  (This package
doesn't need a lot of attention, as it's automatically updated with
git, and stable upstream.)
Limit the data and stack sizes on SunOS.  This gets the build much further
and able to run the compiler, now failing in the documentation generator.
