423e8b2f03 Revert "pipewire-alsa: Make it MT safe" 
This reverts commit f22dd9d781.

Obsolete now that pw_init and factory loading/unloading has been
made thread safe.

64f83158f4 alsa-plugin: improve error handling and recovery 
Ignore -ENOENT errors, they are likely because some device was
removed.
Make sure we clear the poll descriptor when nothing is pollable, even
in the error case.
Clear the error after we reported it instead of reporting it forever.

Fixes #1627

f5d51162c4 treewide: mark things static and const 
Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.

All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.

5ee9133b60 alsa plugin: allow specifying a media.role on the virtual device name

59407d2f08 includes: update all references to extensions to point to pipewire/extensions 
This also brings the advantage that all tools, examples, modules, components
can also be compiled standalone out-of-tree using libpipewire from the system

da339c286f meson.build: drop HAVE_CONFIG_H

the config.h file.

0054319d88 meson.build: add -D_GNU_SOURCE to the project arguments

for (almost all) executables.

e0471c6757 pipewire: allow NULL pointers in pw_properties_free() 
Just like the real free() we should just ignore a NULL pointer, makes the
caller code easier for those instances where properties are optional.

Patch generated with concinelle with a few manual fixes.

5a186ece01 alsa: handle plugin errors better 
When the plugins can't be loaded, we fail to make a main_loop.
Handle this case instead of segfaulting.

2405f0942b spa/buffer: rename SPA_MEMBER to SPA_PTROFF 
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).

223f20709d meson: replace join_paths(a, b) with a / b 
More readable and from the meson reference manual:
(since 0.49.0) Using the/ operator on strings is equivalent to calling join_paths.

877309bfbe use priority.session to select the default sink/source 
priority.session is meant to be used to set routing priorities.

priority.driver is meant to be used by the scheduler to select what
nodes is best for driving the graph. This usually depends on the
hardware quality and the use case (Pro Audio devices are likely
to be used as driving the graph).

c8fd34a41d metadata: store default-nodes as JSON 
Don't just store the id in the metadata but a JSON object with
the node name. This makes it possible to easily introspect the
metadata and also extend the metadata with more fields later.

Instead of matching the metadata id to the global ids we now
have to match it against the name.

0aadc0450d alsa: implement poll_descriptors

in the following poll based on the buffer filled levels. Some API
is very sensitive about this, it seems.

8386ddff78 alsa-plugin: Fix default channel layout

channel map.

92c541ea03 pipewire-alsa: Make sure to always fill the pipewire buffers with

actually pause the device.
