Update gstreamer 1.0 ports to version 1.2.4.

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).

Stagify Gstreamer ports.
Fix build of gstreamer and gstreamer1 with glib 2.38.x [1].
Update gstreamer and gstreamer-plugins to new rules, USES=gmake pathfix,
new LIB_DEPENDS syntax.
Only pull in flex if base version is too old.
Be more selective for which OSVERSIONS we need gcc due to the clang bug.

Add NO_STAGE all over the place in preparation for the staging support (cat:
multimedia)

Add Gstreamer 1.0.7. This is the new stable version of the
Gstreamer multimedia framework.

Use the USE_GSTREAMER1 macro to select Gstreamer 1.0 plugins. A new chapter
for the porters handbook about gstreamer is a work in progress.

X related plugins are now stand alone. The gio plugin is now part of the
gstreamer1-plugins port and the oss plugins are now part of the
gstreamer1-plugins-good port.

Note that the pulseaudio plugin is missing because it needs a newer version
of pulseaudio. Also there are still a number of plugins from -bad which
haven't been ported to the 1.0 API yet.
