- revised most removed/outdated/obsoleted patches patches:
-- codecs - now it works fine without w32codecs
-- home_etc - mplayer now supports MPLAYER_HOME environment variable, should be
	enough
-- system-amr - outdated, mplayer uses external libopencore-amr now
-- pcmsplit - "split in 10 megs audio files" - patch is useless
-- mythtv - seems like mythtv internal nuv is supported by upstream mplayer
	already, can anyone verify that ?
-- xvmc - not supported, but patches at openchrome.org are completely outdated
	and implementation changed to much to try to update it

Changed files:
    mplayer-system-amr.patch -> 1.4
    mplayer.spec -> 1.425
