20c38f2e70 lavf/mov: don't read outside frag_index bounds 
Potentially fixes:
https://bugs.chromium.org/p/chromium/issues/detail?id=786269#c1

In theory, the crash can be triggered by an invalid stream that has
either tfdt or trun outside of the moof

These tables are static so they should only be initialized once

4fb20d4e3a configure: call flatten_extralibs in a subshell 
By putting the call in a subshell, the problem of it spilling
cleanup-decision from a previous library to other libraries is avoided.

For example, it could have already cleaned up cuda_extralibs in a
previous library that depended on cuda. Then when it gets to avutil, it
will never pick up the dependency of avutil to cuda, which depends on
libdl, which in turn results in a missing -ldl extralib, resulting in
link failures in certain configurations.

bad7ce1d82 makedef: Pass EXTERN_PREFIX from configure to makedef 
This avoids having to use either "dumpbin -headers" to find out
the current architecture, or pass $ARCH from configure to deduce it.

When configuring with --disable-asm, ARCH is equal to "c", which doesn't
give any indication of what symbol prefix is to be used.

bb4c9d0a8e avcodec: Don't assume separate u and v planes in ff_alloc_picture 
alloc_frame_buffer in ff_alloc_picture asserts that the linesize
of planes 1 and 2 are the same. If the pixfmt has a single uv
plane, like NV12, this won't be true.

So, let's only do this check if there are more than 2 planes.

We never hit this with previous hw formats because they don't set
linesize to meaningful values, but the cuda hw format sets the
values based on the underlying data layout.
