790f793844 avutil/common: Don't auto-include mem.h
There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.

Keep it for external users in order to not cause breakages.

Also improve the other headers a bit while just at it.

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.

also avoids relocations.

59c9dc82f4 avformat/avformat: Move AVOutputFormat internals out of public header
This commit does for AVOutputFormat what commit
20f9727018 did for AVCodec:
It adds a new type FFOutputFormat, moves all the internals
of AVOutputFormat to it and adds a now reduced AVOutputFormat
as first member.

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

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.

5ca535ee9a avformat/hashenc: Deduplicate AVClasses
The child_class_next API relied on different (de)muxers to use
different AVClasses; yet this API has been replaced by
child_class_iterate.

c371463915 avformat: remove avio_flush() calls from the end of write_packet functions
Removing explicit avio_flush() calls helps us to buffer more data and avoid
flushing the IO context too often which causes reduced IO throughput for
non-streamed file output.

The user can control flushing behaviour at the end of every packet using the
-flush_packets option, the default typically means to flush unless a
non-streamed file output is used.

Therefore this change should have no adverse effect on streaming, even if it is
assumed that a new packet has a clean buffer so small seekbacks within the
output buffer work even when the IO context is not seekable.

c05d82fa92 avformat: remove unneeded avio_flush() calls from the end of write_trailer functions
The IO context is always flushed by libavformat/mux.c after write_trailer is
called, so this change should have no effect at all.

666b427881 avformat/hashenc: use an array of hashes
Only the first element of the array is used currently, the other
elements are in preparation for a new muxer calculating multiple
hashes.

Also move alloc/init code from the write_header() functions to
dedicated init() functions, and the cleanup code from the
write_trailer() functions to dedicated deinit() functions.

hash_free() and framehash_free() turn out to be identical here,
but will differ in the subsequent commit, so they are not consolidated.
