Register a pthread cleanup handler to guarantee
that `spa_source::{priv, rmask}` are cleared even
if the thread is cancelled while the loop is dispatching.
This is necessary, otherwise `spa_source::priv` could point
to the stack of the cancelled thread, which will lead to
problems like this later:
Program terminated with signal SIGSEGV, Segmentation fault.

AVDTP (v1.3 Sec 5.3) has a limitation that a local SEP (on the same
adapter) can be connected to at most one remote SEP. Trying to do have
it connected to multiple remotes either fails or causes misbehavior
later on.
Skip SetConfigure the same local endpoint for multiple remote ones in
codec switch. BlueZ observes this restriction in SelectConfiguration,
so also it won't try to do invalid configurations.
In BlueZ 5.64, the SetConfiguration calls succeed, but subsequent
transport acquires will fail. (Likely already the SetConfiguration DBus
call should fail.)
This all has the consequence, with the current approach to the
codec=endpoint correspondence, that if multiple devices are connected to
the same adapter, they currently have to use different codecs.
When uclibc is build with !UCLIBC_HAS_LOCALE the macro
__LOCALE_C_ONLY will be set, use this to disable unsupported and
not required(due to only supporting the C locale) locale functions.

Improve the debug_params output.
Always either print the failed filter or that there was no filter.
Print the index of the enumerated failed param or a message when
there are no params.
See #2383
After emiting the node info, remove the properties from the info again
so that we don't accidentally emit them again later, when the
info and properties are out of scope.
Try 8 times to make progress, if nothing after that, xrun.
A stream that keeps sending 0 sized buffers would otherwise get into
an endless loop.
See #2359
The file name "lc3.h" in the ETSI LC3plus package may conflict with the
actual LC3 codec, so try to find a file "lc3plus.h" instead. Also try
to find a pkg-config dependency for it first (in which case use lc3.h,
assuming it's in different directory). This can be fine tuned, if
something starts to package that library.
LC3plus expands 509 bytes input -> 7680 bytes output, which is bigger
than current decode buffer.
Make the decode buffer bigger, and put it on heap, not stack.
Codecs may need to fragment a single encoder frame across multiple
packets that are sent consecutively.
Allow codec->encode() to set need_flush=NEED_FLUSH_FRAGMENT, so that
sink should immediately call start_encode + encode with NULL input data,
to produce the next packet.
Previously, other return values than need_flush=1 were unused, so no
need to bump codec ABI for this.
We need exactly 4 hex characters, everything else is refused. We
also copy those characters directly to the output string without
assuming any encoding.
See #2337
Codec switch flag should be cleared on device connection status change,
to deal with codec_switched() callback not being called if device is
suddenly disconnected.
When device is disconnected, running codec switches are not meaningful,
and should be stopped.
The codec switch callback may also trigger A2DP profile switch, which
may reconnect the device. Fix it so this does not happen.
