With glibc 2.16, we get following build error when building jack2:

  [193/247] cxx: tests/iodelay.cpp -> build/tests/iodelay.cpp.4.o
  ../tests/iodelay.cpp:171:43: error: 'UINT32_MAX' was not declared in this scope
  ../tests/iodelay.cpp:171:55: error: 'UINT32_MAX' was not declared in this scope
  ../tests/iodelay.cpp:172:44: error: 'UINT32_MAX' was not declared in this scope
  ../tests/iodelay.cpp:172:56: error: 'UINT32_MAX' was not declared in this scope

In glibc 2.17 or older version, Header <stdint.h> defines these macros
for C++ only if explicitly requested by defining __STDC_LIMIT_MACROS.

We can't use <cstdint> since it requires C++11 standard.

jack_latency_range_t is

struct _jack_latency_range {
    jack_nframes_t min;
    jack_nframes_t max;
};

and jack_nframes_t is

typedef uint32_t        jack_nframes_t;

so it's unsigned. Initialising it with -1 is invalid (at least in C++14). We cannot use {0, 0}, because latency_cb has

   jack_latency_range_t range;
   range.min = range.max = 0;
   if ((range.min != capture_latency.min) || (range.max !=
       capture_latency.max)) {
       capture_latency = range;
   }

so we must not have {0, 0}, otherwise the condition would never be true.

Using UINT32_MAX should be equivalent to the previous -1.

Space required before macro. No functional changes.

If configured with --clients=512 (translates to CLIENT_NUM), we exceed
the maximum stack size. CLIENT_NUM==500 still works, but let's allocate
the matrix on the heap to be safe.

Kudos to Markus Seeber for the initial bug triage.

Fixes #212

Add support for nios2

When compiling jack on nios2, 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.

Fix Netjack crashes due to broken alignment

Use ARM neon intrinsics for AudioBufferMixdown

Correct JackDriver::Open : call to fGraphManager->SetBufferSize has to use current fEngineControl->fBufferSize value.

Correct midiseq.c : better use jack_midi_reset_buffer instead of jack_midi_clear_buffer for output port.

This makes sure header checks work when the third party package is
installed in a non-standard location, as long as a pkg-config file is
found.

It is already defined by conf.define().
