SWS_CPU_CAPS are deprecated and slated to removed with libswscale major
version 3. No need to provide a SWS_CPU_CAPS_MMX2 as backward
compatibility define under the same explicit condition.

s->mb_x is reset to zero a couple of lines above. It does not make
sense to call ff_er_add_slice() with 0 as endx when the end of the
macroblock row was reached. Fixes unnecessary and counterproductive
error resilience in https://bugzilla.libav.org/show_bug.cgi?id=394.

Fixes a crash with zuffed files.

Use a different char* for extracting info string from the URL. The
other pointer can be made const then which elimates the need for a
cast and fixes the following warnings:
warning: to be safe all intermediate pointers in cast from ‘char **’ to
‘const char **’ must be ‘const’ qualified [-Wcast-qual]

Check the number of index tables before using byte offset based seeking
instead of the index_tables pointer.

This code spews a multitude of warnings with glibc (unchecked
return values), some of them possibly warranted.  Furthermore,
the deamonisation is not suitable for use with typical startup
scripts as it does not provide the PID of the daemon in any way.
Users wishing to run avserver as a daemon can still do so using
start-stop-daemon or equivalent tools.

The options USE_INLINE_TREES, SHOW_DIRECTORIES and HTML_ALIGN_MEMBERS
became obsolete with doxygen 1.8.1 (releaded 2012-05-19). The generated
outpu for older doxygen versions should not change since they were set
to the default value.

The -mpowerpc64 and -mpowerpc-gfxopt flags are implicitly set by
-mcpu as needed.  Passing them explicitly is redundant and can
conflict with user-supplied flags.

This removes an inter-library dependency on ff_log2_tab causing
linking errors in some configurations.

Since the pointer `oc' is NULL, oc->oformat->name will cause a null
pointer dereference.  This patch changes it to seg->oformat->name.

Was left out from c1a02e88.

It is used only in one place and is unlikely it would be needed
elsewhere.

Deprecate avcodec_get_chroma_sub_sample.

Simplifies usage but has higher latency.
