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.

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.)

4f98bf9dbd avformat/avio_internal: Don't include url.h 
It is only included because two very rarely used functions
use pointers to URLContexts; use struct URLContext instead.
Also move ffio_geturlcontext() so that one can avoid
a forward declaration of struct URLContext (which would be
necessary as soon as FF_API_AVIODIRCONTEXT is no more).

lpd.buf is non-const and discards the const qualifier of zerobuffer.
This fixes -Wdiscarded-qualifiers observed with a variety of compilers, including GCC 5.2.
Note that this does not change the type of zerobuffer, and merely makes the intent explicit.
