073251316e avformat: Make init function out of write_header functions if possible 
Also mark them as av_cold while just at it.

a24bccc238 avformat/mux: Add flag for "only default codecs allowed" 
AVOutputFormat has default codecs for audio, video and subtitle
and often these are the only codecs of this type allowed.
So add a flag to AVOutputFormat so that this can be checked generically.

03b04eef72 avformat: Enforce one-stream limit where appropriate 
Several muxers (e.g. pcm muxers) did not check the number
of streams even though the individual streams were not
recoverable from the muxed files. This commit changes
this by using the FF_OFMT_MAX_ONE_OF_EACH flag
where appropriate.

b800327f4c avformat/avformat: Add FFInputFormat, hide internals of AVInputFormat 
This commit does for AVInputFormat what commit
59c9dc82f4 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.

This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).

This is possible since 50f34172e0
(which removed the last usage of an internal field of AVInputFormat
in fftools).

(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

a78f136f3f configure: Use a separate config_components.h header for $ALL_COMPONENTS 
This avoids unnecessary rebuilds of most source files if only the
list of enabled components has changed, but not the other properties
of the build, set in config.h.

c1e439d7e9 avformat: Forward errors where possible 
It is not uncommon to find code where the caller thinks to know better
what the return value should be than the callee. E.g. something like
"if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit
changes several instances of this to instead forward the actual error.
