Makefile.am: Fix for newer versions of automake

Newer automake doesn't support including out-of-dir C files to
the `*_SOURCES` line. Instead use libraries.

Fix typo in property.c

Fix thread priority and permit multiple instance of zita_a2j/j2a

This subtraction (a) can create negative values (b) doesn't make any sense since we just add 10 to the jack priority later.

As rightly suggested by rgareus (x42@github), JACK2's version of
midi_dump.c is better in every possible aspect and should hence be
copied.

This reverts commit 6598c7e1bc.

Need to branch in submodules before doing work here.

According to the ALSA documentation, snd_pcm_readi() returns -ESTRPIPE
when a suspend event occured. But xrun_recovery() checks for -EAGAIN
instead.

If the ALSA client is connected to the ALSA loopback device, it leads to
an infinite loop in the client when the computer is resumed from sleep.
The client takes up to 99% of the CPU resources.

The problem is fixed by a proper error checking of snd_pcm_readi().

A word of caution however: on kernels prior to 3.8, it will trigger a
bug in the snd-aloop driver, and may lead to a kernel oops.
The kernel fix can be found there:
