New functions can get values from child objects, properly report error
codes and have consistent naming and signatures.

Deprecate av_set_*

New functions support setting values on children, return error codes
instead of options and have consistent naming and signatures.

This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)

This will also allow the new setting/reading API to transparently apply
to children contexts.

Also stop attempting to honor the alloc parameter, as things break
horribly in that case.
It will be removed in upcoming successor to av_set_string3.

It's a hack which was created to allow for multiple options with
different defaults to refer to same field (e.g. 'b' vs 'ab'). There is
no need for it anymore.

Also change it to be more readable.

Fixes bug 28.

It allows to search for options only with AVClass, without allocating
the corresponding context.

This way the caller can pass all the options in one nice package.

This breaks API and ABI.

Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".

Install each library's headers in $prefix/include/$libname.
The installed headers use #include "lib*/*.h"; applications
are expected to do the same.

Specify only $prefix/include in .pc files.
