56af0bc10f configure: Check for strtoll and redirect to _strtoi64 in the msvcrt block 
This allows doing this redirection, if building with clang against
old enough MSVC headers that lack strtoll (2012 and older).

7f549b8338 riff: don't overwrite bps from WAVEFORMATEX if EXTENSIBLE doesn't contain that data. 
According to the specification on the MSDN [1], 0 is valid for that
particular field, and it should be ignored in that case.

6135c3b61e Revert "avprobe: Zero the allocated avio buffer memory" 
This reverts commit 0e0538aefc.

The valgrind warning was a false positive due to OSX implementation of
printf (invoking a strnlen), while this code is actually fine, since the
format specifier %.*s guarantes that no more than buf_size bytes from
buf will be read.

f637046d31 libavutil: Always use some GCC style attributes on clang 
Clang normally disguises as GCC (defining __GNUC__), and thus get
all the normal GCC specific attributes.

Clang can also work as a drop-in replacement for MSVC, and in these
cases, it doesn't define __GNUC__, but defines _MSC_VER instead.

Even in these setups, it still supports the GCC style attributes,
thus use them, especially where there isn't any MSVC specific
version, or where the MSVC specific version doesn't work on clang
(for DECLARE_ASM_CONST).

ed9b2a5178 mov: Rework the check for invalid indexes in stsc 
There are samples with invalid stsc that may work fine as is and
do not need extradata change. So ignore any out of range index, and
error out only when explode is set.
