avformat/utils: never decrease has_b_frames in compute_pkt_fields()

The intent of the original check was to increase has_b_frames when
it was incorrectly set to 0. Later codecs allowed larger values

avcodec/x86/hpeldsp: fix crash on AMD K6-3+

There are instructions pavgb and pavgusb. Both instructions do the same
operation but they have different enconding. Pavgb exists in SSE (or
MMXEXT) instruction set and pavgusb exists in 3D-NOW instruction set.

livavcodec uses the macro PAVGB to select the proper instruction. However,
the function avg_pixels8_xy2 doesn't use this macro, it uses pavgb
directly.

As a consequence, the function avg_pixels8_xy2 crashes on AMD K6-2 and
K6-3 processors, because they have pavgusb, but not pavgb.

This bug seems to be introduced by commit
71155d7b4157fee44c0d3d0fc1b660ebfb9ccf46, "dsputil: x86: Convert mpeg4

x86: vp8dsp: Split loopfilter code into a separate file

configure: Properly check for availability of -Wno-foo warning flags

For some weird reason gcc does not check if the -Wno disabling variants
of warning flags match existing warning flags. Instead it swallows them
silently. That is, unless other warning or error messages are generated,
because then - for some even more bizarre reason - a complaint about the
unknown disable warning flag is issued along with the error or warning
message.

Thus to check for the availability of a warning disabling option, one
needs to check for the enabling variant instead and then add the
disabling variant to CFLAGS.

configure: Split test_cflags function off from check_cflags

This is useful to test flags without directly adding them to CFLAGS.

avformat/isom: lpcm in mov default to big endian

It is my understanding that "Unless otherwise stated, all data in a
QuickTime movie is stored in big-endian byte ordering" [1] in MOV files.

I have a couple of thousand files, which technically are invalid because
their sound sample description element 4CC is 'lpcm' but its version is
0 - and "Version 0 supports only uncompressed audio in raw ('raw ') or
twos-complement ('twos') format" [2]

Because isom.c only contains a mapping for 4CC 'lpcm' to
AV_CODEC_ID_PCM_S16LE, these files have their audio decoded as LE when
it is actually BE.

This commit adds AV_CODEC_ID_PCM_S16BE as the first match for 4CC 'lpcm'.
