Stefano Sabatini e2959f4558 Make av_strerror() return -1 even in the case when av_strerror_r() is
not defined.

This allows applications to check if av_strerror() cannot provide a
meaningful representation for the provided error code, without having
to actually check the filled string.

Stefano Sabatini 441ea0ce91 Make av_strerror() print an error message mentioning the error code
number if strerror_r() did not succeed for whatever reason.

This avoids the need for the application to fill the string in case
strerror_r() fails, for example because the error code is not known.

instead which is semantically equivalent.
