It seems the specification does not limit the value to 32bit

This patch improves the logs when the message "cur_dts is invalid" appears.
If helps to identify which stream generates the trouble,
and the status of the stream.
A lot of users suffers with the message, and the origin varies.
The improved message can help to discover the cause.

The transcode() helper function will already prepend the TARGET_PATH to
the sample path, if its a relative path. This avoids an issue on
Windows, where the relative path check could fail.
Silences several warnings:
libavutil/hwcontext_d3d11va.c:413:49: warning: passing argument 3 of ‘av_image_copy’ from incompatible pointer type
libavutil/hwcontext_d3d11va.c:425:47: warning: passing argument 3 of ‘av_image_copy’ from incompatible pointer type

libavutil/hwcontext_dxva2.c:382:52: warning: passing argument 3 of ‘av_image_copy_uc_from’ from incompatible pointer type
Fixes a bogus compiler warning (max_samples_per_frame is checked):
libavcodec/alac.c: In function ‘allocate_buffers’:
./libavutil/internal.h:142:9: warning: argument 1 value ‘18446744073709551552’ exceeds maximum object size 9223372036854775807
The spec defines it as an array of signed values, inferred to 0 when not
present.

Use a macro to redirect calling code from the official name to the
ff_ prefixed one.
Detecting these functions in configure can be tricky (on mingw, they
are conditionally available depending on posix feature defines).
If configure didn't detect them, but they still are visible at
compile time (due to an unrelated header defining the posix feature
defines), providing the local fallback versions with a prefixed
name is safer.

These functions are available in time.h (conditional on posix thread
safe functions) on mingw.
Previously, these functions weren't detected by configure, and
libavutil/time_internal.h provided replacements, even if time.h
actually contained definitions of them.
These mingw inline functions are currently defined as
"extern __inline __attribute__((__gnu_inline__))". In this case,
redefining a new static inline version of the same function with the
same name is tolerated.
