Fixes compilation for --disable-everything --enable-parser=dvd_nav

mpeg: Add passing DVD navigation packets (startcode 0x1bf) to caller to allow better playback handling of DVDs.

The two types of packets (PCI and DSI) are passed untouched but combined by the new codec ID AV_CODEC_ID_DVD_NAV.
 The first 980 bytes in the packet contain the PCI data. The next 1018 are the DSI data.

Only compile if CONFIG_ENCODERS is enabled, i.e. if at least one
encoder is to be compiled. This prevents it from being includes in
a decoder-only build.

The sh4 optimizations are removed, because the code is
100% identical to the C code, so it is unlikely to
provide any real practical benefit.

This allows us to remove FF_IDCT_WMV2, which serves no practical purpose
other than to be able to select the WMV2 IDCT for MPEG (or vice versa)
and get corrupt output.

Fate tests for all wmv2-related tests change, because (for some obscure
reason) they forced use of the MPEG IDCT. You would get the same changes
previously by not using -idct simple in the fate test (or replacing it
with -idct auto).

Conveniently (together with Justin's earlier patches), this makes
our vorbis decoder entirely independent of dsputil.

There is only about 4 lines of common code, so it alot cleaner
when seperated.

The decoder also supports a12v, but removes the transparency layer
since no samples with actual transparency are available for testing.

Snow is a toy codec with no real-world use and horrible code.

Note that the linebreaks text codec option (but not the feature) has
been removed; its main goal was to allow demuxers to configure the text
decoder (and not meant to be used by users), but the AVOption are not a
viable solution. This is solved differently in this commit.

g723_1 decoder needs celp_math.o because it calls ff_dot_product().

Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().
