In the DASHContext structure, min_seg_duration is declared as an int,
but the AVOption list claimed it was an INT64. Change the option list
to use the correct size, which should fix some initialization errors
seen on big-endian platforms.

For some strange reason "-t" option was only implemented
for input files while both "-t" and "-to" were available
for use for output files. This made extracting a range from
input file inconvenient.
This patch enables -to option for input so one can do
ffmpeg -ss 1:23:20 -to 1:27:22.3 -i myinput.mkv ...

This is mostly straight-forward. The weird part is that it should
just work for mpeg1, but I see corruption in my test cases, so I'm
going to try and fix that separately.
I took the reference lookup code from the vp9 hwaccel where the
type is unsigned char, but for vc1, the type is signed int.
This is particularly important because the value used when there's
no reference is different (255 vs -1).
It didn't seem to break anything, but for mpeg1/2/4, this mistake
caused decode errors.
Add to libavcodec/tests/.gitignore an entry for test
program libavcodec/tests/mpeg12framerate . Other
similar test programs, e.g. jpeg2000dwt and dct, are
ignored in a similar way.
On initially checking out master, and doing "./configure"
and "make clean", "git status" reports no untracked
files. After running "make fate", "git status" reports
untracked file "libavcodec/tests/mpeg12framerate".
mpeg12framerate is a unit test program. It was apparently
introduced in commit
278c308cea, on
Tue Sep 12 22:11:56 2017 +0100. It added a new function
ff_mpeg12_find_best_frame_rate() to
libavcodec/mpeg12framerate.c , and the code in
libavcodec/tests/mpeg12framerate.c to exercise that
function. This commit also added the new program to
the FATE suite, but it omitted a .gitignore entry.

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.

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.
