[PATCH 00/11] libavformat/asf: fix handling of byte array length values

[ffmpegagent <ffmpegagent@gmail.com>]

The spec allows attachment sizes of up to UINT32_MAX while we can handle
only sizes up to INT32_MAX (in downstream code)

The debug.assert in get_tag didn't really address this, and truncating the
value_len in calling methods cannot be used because the length value is
required in order to continue parsing. This adds a check with log message in
ff_asf_handle_byte_array to handle those (rare) cases.
