GstBitWriter provides a bit writer that can write any number of
bits into a memory buffer. It provides functions for writing any
number of bits into 8, 16, 32 and 64 bit variables.

gst_buffer_list_new_sized(0) will cause an underflow in a calculation
which then makes it try to allocate huge amounts of memory, which
may lead to aborts.

Update documentation on non existent option `gst-enable-gst-debug'. Instead,
one has to make sure that the `--disable-gst-debug' option was not used when
compiling GStreamer (i.e., `./configure --disable-gst-debug').

Meson supports building both static and shared libraries in a single
library() call. It has the advantage of reusing the same .o objects and
thus avoid double compilation.

So we don't unnecessarily scan directories that have no plugins
(or try to open libs). Matches how we limit the search space for
plugin modules to gst/ ext/ sys/ subdirs.
Catch users wrongly setting foreign pads or wrong pads as
the selector's active pad, which leads to all kinds of
other issues. It's a programming error so handle it just
like we would if we had direct API.

In the case where the user sets a new padprobeinfo->data in a probe
where the data is a sticky event, the new sticky event should be automatically
sticked on the probed pad.

RISC-V supports unaligned accesses, but these might run extremely slowly
depending on the implementation. Therefore set GST_HAVE_UNALIGNED_ACCESS
to 0 on this architecture.

And make the drop() functions expect a 0-based index too,
this addresses a longstanding FIXME. This will not break
backward compatibility, because the drop() functions
were previously only meant to be used with the index
returned by find().

This commit makes it possible to reuse a sample object and avoid
unnecessary memory allocations, for example in appsink.
In addition, writability is now required to set the buffer list.

When outputting debug logs on Windows, some sections are protected
with a non-recursive lock. Turns out though that gst_debug_message_get()
might indirectly, via our printf format extensions, call code which
in turn would try to log something when it can't handle something. If
that happens we end up in gst_debug_log_default() again recursively and
try to again take the lock that's already taken, thus deadlocking.
Format the debug message string outside of the critical section
instead to avoid this.

Remove unneeded reapplication of patterns. Besides being
superfluous (gst_debug_reset_threshold already applies
patterns) it was also wrong and didn't stop checking patterns
after the first match (broken in 67e9d139).
Also fix up unit test which checked for the wrong order.

Replace the while+goto with a for+break and check walk to determine
whether we had a match. Move up the unlock to keep the locked section as
small as possible.

Move the match, logging and set_threshold to a new function.
The log levels are different, so choose the higher one (LOG). Having two
equivalent messages at two different levels seems like a bad idea
anyway.
