This practice is not supported by the MinGW developers, and even requires
patching the MinGW runtimes in newer versions. Furthermore, we now support
build with MSVC, so this section is rendered useless.

It is not correct in all cases and it is less predictable than a skip of 0

The value should be always 3, as it follows from the specification.
Fix a stack buffer overflow in exponents_from_scale_factors as reported
by asan. Thanks to Dale Curtis for the sample vector.

This way we can directly remap channels from Opus' channel order to
libav's internal channel order, instead of mapping channels from
Opus' order to Vorbis' order then to libav's order.

I was sadly unable to find a non fuzzed mp3 that uses the
feature that contained the bug (and i searched hard ...), thus
while this fixes the security issue. It may or may not fix
mixed blocks in 8khz mp3s, i cant say due to lack of samples to test.
Security issue exists since: b37d945dd4

Use the MAX_URL_SIZE define where applicable. Increase buffer
sizes for all buffers that need to fit a long pathname - buffers
that need to fit only the hostname (and other short strings, but
not the pathname - such as "headers" in http_connect) are kept
at 1024 bytes for now.
Also increase the max line length in http_read_header, since it
might need to contain a full url for Location: redirects.

Fixes some DNXHD files generated by AVID TM, where codec UL was set to A-law
meanwhile the real audio codec was PCM S16. According to SMPTE RP 224, A-law is
the default value for sound essence parameters therefore we should handle it
specially.

Implement av_buffersink_read() and av_buffersink_read_samples()
for ffmpeg's version of buffersink.
With this change, avconv linked against ffmpeg's libraries passes
the same number of tests whether it uses ffbuffersink or
buffersink_old.
