Cleanup plist

- Drop .la files, no dependees require them

Approved by:	portmgr blanket

Convert a bunch of USE_BZIP2 to USES=tar:bzip2

Approved by:	portmgr (not really, but touches unstaged ports)

When linking a library libA with a library libB using libtool, if libB.la
exists, libtool will add all libraries libB.la refers to (dependency_libs
field) to the linker command line and store them in the dependency_libs
field of libA.la.  So everything that subsequently links with libA will also
link to these extra libraries.  This causes too much overlinking.

This commit modifies Mk/Uses/libtool.mk so it empties the dependency_libs
field in .la libraries during staging.  However, because .la libraries have
very limited use when dependency_libs is empty it makes sense to completely
remove them during staging.

So with this commit USES=libtool is modified to remove .la libraries and a
new form (USES=libtool:keepla) is introduced in case they need to be kept
(dependency_libs is still emptied).

Convert to USES=libtool
Convert to USES=dos2unix
Remove now useless patch for DOCS support

Eradicate USE_GNOME=pkgconfig from devel
While here:
USE_GMAKE->USES=gmake

USE_PERL5*->USES=perl5

Remove USE_GNOME=gnometarget from ports. It has been a empty keyword since
mid 2008.
