0ba5299a80 movenc: use the "encoder" metadata tag to write stsd Compressorname 
This mirrors the demuxer behaviour and avoids accessing
AVCodecContext.codec, which should not be done in muxers.

79f2c426fd dv: do not set codec timebase

c3311d472a avienc: sanitize variable naming in write_header() 
Do not call an AVCodecContext 'stream', that is highly confusing.
Also, add a local variable for the current AVStream in the loop over all
streams.

b513bf6f69 yuv4mpegdec: do not set coded_frame properties

fd056029f4 lavc: add avcodec_free_context(). 
Right now, the caller has to manually manage some allocated
AVCodecContext fields, like extradata or subtitle_header. This is
fragile and prone to leaks, especially if we want to add more such
fields in the future.

The only reason for this behaviour is so that the AVStream codec context
can be reused for decoding. Such reuse is discouraged anyway, so this
commit is the first step to deprecating it.

reason for any locking.

4d25c2bc76 build: Support building using clang-usan and disable-optimization 
Clang Undefined Behaviour Sanitizer seems to make non-constant constant
expressions, making the compilation fail when they are used within
inline assembly if no optimization is requested.

Add -O1 to the cflags to hide the misbehaviour.

c9281a01b7 lavf: drop the zero-sized packets hack

0c1959b056 lavf: add AVFMT_FLAG_BITEXACT. 
Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's
codec context.

Using codec options inside lavf is fragile and can easily break when the
muxing codec context is not the encoding context.
