Previously we were creating freeswitch-music, freeswitch-sounds,
freeswitch-sounds-en, and freeswitch-sounds-en-us metapackages and
also providing those names as virtual packages from the
freeswitch-{sounds,music} source packages.  This is unnecessarily
confusing and meant that freeswitch-all wasn't depending on any sounds
in actuality as it was also providing freeswitch-sounds.

We were generating freeswitch-mod-mod-* rather than freeswitch-mod-*.

Conflicts:
	freeswitch.spec

This affects the set_fs_ver bash function and the
./build/set-fs-version.sh script.

Previously we were failing to quote the value of
SWITCH_VERSION_REVISION_HUMAN when inserting it into configure.in.
When it contains spaces, which it often does, this results in a
malformed line in the generated configure script, which results in the
define in src/include/switch_version.h.in being left unset.
