Surprisingly neither GCC nor Clang did this transformation on their own.

If an URI indicated that the data protocol was in use, it would be
copied into a temporary buffer via strncpy(dst, src, strlen(src)),
thereby ensuring that the trailing \0 would not be copied, despite dst
being uninitialized. dst would then be av_strdup'ed, leading to
potential segfaults.
The solution to this is simple: Don't copy the URI in the temporary
buffer at all, instead av_strdup it directly.
This fixes a -Wstringop-truncation warning emitted by GCC 9.2.

By itself, this allows 6-point, 10-point and 30-point transforms.
When the 9-point transform is added it allows for 18-point FFT,
and also for a 36-point MDCT (used by MP3).
and also add padding to it; moreover, don't use memcpy to write one byte
to extradata.

Up until now, the name of every AVBSFContext for logging purposes was
"AVBSFContext", so that the default logging callback produced output
like "[AVBSFContext @ 0x55813bae92c0] Extradata". This has been changed
to "[trace_headers @ 0x60a000000700] Extradata" by adding an item_name-
function to the AVClass for bitstream filters.
Furthermore, the correct category has been set so that the introductory
part before the actual message (everything before "Extradata" in the
above examples) are displayed in a different colour than the rest.

another 'd' at the end is wrong and just leads to warnings that say

2d').
