This fixes the case where linking fails if libinstpatch is not installed in a system/default location but instead needs to be found through `PKG_CONFIG_PATH`.
For some use cases it is necessary to specify -fPIC even if we build
static library e.g. building vst plugins (*.so) which may not load
shared libraries from outside the system paths (depends on DAWs).
For such environment we would like to build the final shared library
without depending on `libfluidsynth.so(.*)` but if we build libfluidsynth.a
it always comes without -fPIC. This change makes it adjustable.
During the creation of a jack audio driver, it is checked whether the sample-rate of the settings object matches jack's rate. If not, it was adjusted previously via fluid_synth_set_sample_rate(). Due to the deprecation of that function and removal of real-time capability of the synth.sample-rate setting, a regression was introduced in 5fbddcecc3 causing the synth's sample-rate to be not updated.
This workaround obtains the synth via the settings instance and for now calls the deprecated sample-rate set function.
Use pkg_check_modules to find readline dependencies such as ncurses and
fallback on current mechanism.
This will fix the following build failure when building statically:
/home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabi/8.3.0/../../../../arm-buildroot-linux-uclibcgnueabi/bin/ld: /home/buildroot/autobuild/instance-1/output-1/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib/libreadline.a(display.o): in function `cr':

See discussion in #591 for details. Basically an incorrect size was
being allocated for the CoreAudio buffer list for a device. It was being
allocated by a VLA (which already did not quite fit the semantics of the
list) and the length calculated could be 0 (instead of the size of the
struct with no buffers elements) causing undefined behaviour.
This corrects it to allocate the amount of memory required by the
CoreAudio framework function and adds a check for the size retrieval and
for the dynamic allocation. This change passed UBSan in my test where
before the change it did not.
Fixes#591
