When using AV_NOPTS_VALUE (which expands to INT64_C(0x8000000000000000))
as union initializer for a double field, the c99 converter needs to
interpret this constant when filling the union initializer, and it is
interpreted as a positive value.
When converting AV_NOPTS_VALUE to a double, MSVC 2010 ends up with
the same positive value as the c99 converter, while MSVC 2012 gets
a negative value.
This results in an infite loop in various FATE tests on MSVC 2012.

Instead, add it to all public entry points to avoid these problems.

This ensures the hwaccel privdata does not leak when a frame buffer could
not be allocated (and toggle the assert when the frame is re-used).
Having no frame buffer available is quite common when using the DXVA2
hwaccel in situations where the DXVA2 renderer is being re-allocated, for
example when moving between displays.

Since the conversion to refcounted frames, the tiff decoder
only wrote the metadata into its internal "picture" in its own context,
never exposing the metadata to the user, and eventually leaking the

Instead, properly store the metadata directly into the frame being decoded into.

This field was only ever set and freed from avcodec, and not otherwise

Some implementations of sscanf do not handle a space before a trailing %n
properly.
As an example, MSVC's does this for the second insatnce in this patch, for
an input of "0x3:c0=c1:c1=c0":
1) Match the final "c0" or "c1".
2) Realize it's at the end of the string.
3) Check for %n.
4) There is no %n, but a space instead.
5) Leave 'len' unitilialized.
So, move it out of the sscanf format strings, and call skip_spaces instead.
This bug does not affect skip_spaces since %n is the first and only formatting
string.
