Add support for rlimit.<resource> = <value> in the context.properties to
adjust the rlimits of the process. A value of -1 sets the max limit.
This can be used to increase the number of file descriptors in a
pipewire process when select() is not used, for example. Other resource
limits might be interesting as well maybe.

We handeled "arg1 arg2 ... " before and used to split between spaces to
get the arguments for execvp but that doesn't work so well when there
are arguments with spaces.
Instead use JSON parsing to get the array of arguments. This make it
possible to use [ arg1 arg2 .. ] and quote each arg separately. You
can still use the old method and even double escape:
"\"arg1\" \"arg2 with spaces\"" or
[ "arg1" "arg2 with spaces" ]
Add config options to create and start multiple data loops, each with
their own priority and thread affinity if requested.
Make it possible to assign loop.classes to the data-loops. Use the
node.loop.class to find a data-loop for the node of the same class. Try
to evenly spread the nodes over the available matching loops.
With this, it is possible to separate the processing of the nodes
depending on the classes, like audio/video and improve concurency on
the server.
No attempt is done yet to move nodes between loops or to move
independent nodes to separate data loops.

The min should always be 1. We have other ways of bumping the number of
buffers to 2, like the ASYNC allocation flag which we can set if we are
also doing some async scheduling. We could make this an option later.
Otherwise, we would also allocate 2 buffers by default between the mixer
and the node, which is unnecessary.
Add link.min-buffers option to set the minimum amount of buffers to
create for links. Set this by default to 2 because we really need two
now in case the sink xruns and does async mixing.
Make this an option because in low-memory cases and when xruns are not
expected, we can set this to 1.
false by default, when true, no warning will be logged when the
context.modules in the config is empty. This can be useful when the
application wants to load all the modules itself.
Add pw_conf_section_update_props_rules() that will not only update the
properties of a section but wil also apply rules in section.rules and
match against the context properties.
Use this by default when using pw_context_conf_update_props().
Add a new method to get a string name of the VM type. Place the
cpu.vm.name in the context properties.
This makes it possible to deprecate the vm.overrides with something more
flexible based on rules. Update the conf files and docs to refect this.
Remove some of the hardcoded values (the absolute smallest buffer size,
independent on the sample rate) to a config option. Set it to the
default value of 4, like what it was before.
Change the hardcoded absolute lowest limit to 1 because anything else
does not make sense.
Enforce the quantum-floor when calculating the final graph quantum.
