ALSA added nanosecond timestamps in library version 0.9.1. Use these
instead of microsecond timestamps for reporting audio timestamps as well
as underrun/overrun times.
alsa-lib version 0.9.1 was released on Mar 11 2003. I had fallback code
to use non-hires timestamps, but after 18 years it didn't seem
necessary, and I removed it from this commit.
Avoid compiler warning suggesting the buffer is too small:

This patch fixes a problem caused by special regex characters
appearing in the device names when using the Jack interface to PipeWire.
It is uncommon for JACK ports to have any characters that need to
be escaped in a regex. jackd simply calls the audio interface
"system". However PipeWire uses the device name from ALSA for the
JACK port names. If this contains any special regex characters,
BuildDeviceList would find the device but determine it has 0
input channels and 0 output channels. In my case, I have an RME
Babyface Pro which puts its serial number in parentheses:
$ aplay -l
card 0: Pro70785713 [Babyface Pro (70785713)], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
* Clean up whitespace in src/hostapi/coreaudio in preparation for .editorconfig. Convert tabs to 4 spaces. Indent by 4 spaces. Strip trailing whitespace. Ensure only one EOL at EOF.
Previously, only portaudio.h was installed when building under mingw using
make. This behavior differs from CMakeLists.txt PA_PUBLIC_INCLUDES where
pa_win_*.h header files are installed.
To cross-compile using MXE (https://mxe.cc/) we need pa_win_*.h headers.
Add them to configure.in so that they are installed.
