Add methods activate() that is called before first call to run() when
stream starts and deactivate() that is called after last call to run()
when stream stops. This makes it possible for aec-plugins to reset their
state between streams.
Although pos will be set to 0 in the first iteration, the compiler does
not seem to figure this out, so help it a little:
../spa/include/spa/support/log.h:306:21: warning: ‘pos’ may be used uninitialized [-Wmaybe-uninitialized]
306 | pos += sprintf(str + pos, "%02x ", buf[i]); \
| ^~
../spa/include/spa/support/log.h:301:13: note: ‘pos’ was declared here
301 | int pos; \
| ^~~
A lot of code calls spa_hook_remove() from error paths where the hook
and therefore the list may not have been initialized.
This leads to null-derefences.
Support Opus as A2DP vendor codec.
The specification for vendor A2DP codec is our Pipewire-specific one, so
it is compatible only with devices running Pipewire.
Add an EMPTY chunk flag to mark a piece of memory as 'empty'. For audio
this means silence.
Use the empty flag to avoid mixing 0 samples.
Set the empty flag in output buffers on audioconvert.
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.

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
Make helper method to parse thread properties and add 2 new properties
to control name and stack-size of the thread.
Use properties when creating threads with the default utils.
Use the default thread utils instead of pthread_create so that the
properties are used.
Not all string functions have a POSIX compliant locale aware version
(eg. strtof_l). Instead uselocale [1] should be used, which allows
switching the locale of a thread to a welldefined one and restoring it
afterwards.

And use this in spa_json_format_float() where we also avoid invalid
json floats.
Use json float format in some places where we serialize json floats.
Add a unit test.
See #2223
Resizes the buffer dynamically. Be careful with getting the address
of a pod in the buffer, it might not be valid after building more stuff
with the builder.
Place the methods on the interface so that we can call them.
Rename create to init because that is what it does.
Add support for listener and events so that we can signal property
changes later.
Move all backends to dynamic libaries loaded with spa_plugin_loader so
new backends not needs changes in pipewire or pipewire dependency to
external code

Add an extra private field to the source to store the pollevent of
the current iteration. This changes ABI but it seems an embedded source
is not used outside of our own plugins and the unit test doesn't test
this ABI case.
Whenever a source is removed, we can set the data field of the
pollevent to NULL so that it won't be handled in any iteration anymore.
Avoid dispatching the same event multiple times when doing recursive
iterations.
Add some more unit tests for this.
Fixes#2114
