rd_acquire() is going to assert (or fail) anyway because connection will be NULL.

When compiling jack on aarch64, compilation fails because NGREGS is not
defined. Since this is only for debug output on segmentation faults, stub
the debug print out like it's been done for other platforms before.

rd_acquire() error handling is adjusted to match libdbus error
handling convention:
 * Initialize error before calling rd_acquire()
 * Free dbus error on rd_acquire() failures
 * Always set dbus error on rd_acquire failures, except for
   detected programming errors that now cause taboo assert.

Reportedly, f28523ff54 was incomplete.

SA_SIGINFO isn't defined on hurd, so check before setting it.

This patch was used in Debian since 2010-08-01.

In my case, the siginfo code was -6, causing the sigsegv handling
to crash on its own. This patch adds a range check for siginfo code.

jackdbus needs explicit index because device reservation code
is shared with jackd and waf cannot autodetect this.

New waf syntax for a subst build.

Automatically upgrading to python3 syntax, where possible.

When a parameter is set, jackdbus used to save immediately.
This was quite annoying and ineffective when configuring
lot of parameters without delay. It caused log line to appear
for each parameter set and xml file serialization as well.

This changeset implements delayed save. Parameters are saved
two seconds after last parameter set.

This changeset removes code duplication that was caused by lack of
unified access to parameters in the control API. Adding new virtual
parameters should be much easier now.

It was be problematic in past (FFADO uses libxml as well).
Most systems will have both libxml and expat.
Maintaining two backends is waste of effort.
If needed, the libxml backend can be resurrected.

When server is already in target state, there is no state change
and thus signal for state change should not be emitted

* Don't override detailed error string with generic one
 * Set the D-Bus reply error in case of jackctl_server_stop() failure
 * Set the D-Bus reply error in case of jack_controller_patchbay_init() failure
 * Don't set the D-Bus reply error in case of jack_deactivate() failure because
   this failure does not cause jack_controller_stop_server() failure and thus
   will cause memory leak.
