jack.pc.in:
Add the custom `jack_implementation=jack1` pkgconfig variable to the
generated jack.pc file to be able to distinguish jack implementations.
As jack implementations exist with jack1, jack2 and pipewire-jack, it is
not (easily) possible to distinguish them by looking at the version
alone (particularly the case with jack2 vs. pipewire-jack, as they share
the same headers).

{example-clients,tools}:
Remove directories for obsolete submodules (only partially removed in
https://github.com/jackaudio/jack1/pull/112).

.gitmodules:
Remove the submodules for example-clients and tools, as they are now
tracked in the separate project jack-example-tools
(https://github.com/jackaudio/jack-example-tools).

{Makefile.am,configure.ac}:
Remove all use of example-clients and tools and their respective
dependencies from the build system.

config/os/macosx/README:
Remove mentions of example-clients dependencies from OSX README.

doc/{Makefile.am,reference.doxygen.in}:
Remove all use of example-clients from the documentation generation.

man/*.0:
Remove all man pages now owned by jack-example-tools.

doc/Makefile.am:
Alphabetically sort the list of headers, that are considered for
documentation generation.
Add all current headers.

doc/reference.doxygen.in:
Alphabetically sort the list of headers, that doxygen considers.
Add any missing headers.

Makefile.am:
Sort the list of headers alphabetically and add all missing ones
(systemdeps.h).

jack:
Update the jack headers submodule to the current latest commit.

Fix configure.ac checking for USE_MD5SUM

it is not allowed to test integer like this

configure: update -mmacosx-version-min= to 10.6

This could be done other ways if it turns out there's a flood of
people out there desperate for 10.4 or 10.5 compatibility, but I
expect this is safe enough to solve in the simplest possible way,
which is by just bumping the number here to 10.6.

Fixes https://github.com/jackaudio/jack1/issues/81.

read/write wrappers to handle the case of interruption by system signals

Atomics cleanup

Use atomic_fetch_add from C11's stdatomic if available or fallback to
GCC's __atomic functions.

Remove atomic_add because is can trivially be implemented by calling
exchange_and_add instead.

Using the process realtime priority instead of the thread realtime priority when sufficient.

config/cpu cleanup

Use LC_ALL=C to generate manpage date

ifdef is useless, since the value is always defined (either to 1 or 0) in config.h.

Fix inspired by

  https://svnweb.freebsd.org/ports/head/audio/jack/files/patch-drivers_dummy_dummy__driver.c?view=markup

Also simplified #if condition in libjack/time.c - it's easier to read a positive than a negated
condition.

ifdef is useless, since the value is always defined (either to 1 or 0) in config.h.

Fix taken from

glibc above 2.17 has these functions builtin, so no need to link against librt.

When the macro succeeds, it needs to set the define to 1, not 0.

Also clarify the text message if librt is linked in.

Without this, the user's locale may influence the content of the
manpages (eg juin instead of June for a french locale).

Closes #54, thanks Rui!

Fixes negative values in xrun reports on Linux kernels 4.0 and above.
