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.)

08bebeb1be Revert "all: Don't set AVClass.item_name to its default value" 
Some callers assume that item_name is always set, so this may be
considered an API break.

This reverts commit 0c6203c97a.

0c6203c97a all: Don't set AVClass.item_name to its default value 
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.

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.
