acde43703f avutil/error: Remove size from error_stringtable
This stringtable is a concatenation of strings, with their
own trailing \0. Without an explicit size said stringtable
ends with two \0 (one from the last string and one more
because it is initialized via a string literal); the explicit
size exists to discard the last \0.

Yet this makes GCC (but not Clang) think that this is an
unterminated string, leading to warnings when
-Wunterminated-string-initialization is enabled.
So just remove the explicit size to avoid this.

(An alternative would be to mark this as a non-string
for GCC, but not for Clang, but this has been deemed ugly;
another alternative would be to omit the internal \0 from
the stringtable and use length fields instead, but
the necessary copying code more than outweighs the size benefits
of omitting the \0.)

04a9e2a809 avutil/error: Avoid relocations and unused information
Use a string table instead to avoid relocations and don't add
the tag string to libavutil/error.c: It is only used
during the test program, so move it there.

bcae59b898 avutil/error: Add HTTP 429 Too Many Requests AVERROR code
This is a common error code from e.g. CDNs or cloud storage, and
it is useful to be able to handle it differently to a generic
4XX code.

Its source is RFC6585.

Some of these were made possible by moving several common macros to

so it is necessary to use AVERROR() in order to get a negative
number. This way the successive negative check will not fail, and the
function will print a meaningful error message on the buffer.

AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and
