With this patch it is possibly to start the JACK daemon with a systemd
service file of type notify. The following provides an example service
file:

[Service]
Type=notify
ExecStart=/usr/bin/jackd -d alsa

[Install]
WantedBy=multi-user.target

for all devices.

This is required for example for some adaptive sample rate converters
which are executed on top of JACK. These SRCs are using the time stamp to
calculate the buffer fill level between playback application and sound
card.

This prevents jack control threads from inheriting RT priorities from
other applications that may be using this in another RT thread

Adjusts the permissions of posix semaphores when promiscuous mode is enabled.

Note that changing permissions of semaphores is only supported on linux by
using the /dev/shm filesystem. As of now, linux does not use posix semaphores
anymore so this code is currently unsed.

Adjusts the permissions of linux futexes when promiscuous mode is enabled.

Adjusts the permissions of unix sockets when promiscuous mode is enabled.

Adjusts the permissions of shared memory segments when promiscuous mode is
enabled.

The jack_group2gid() function does a thread-safe lookup of a unix gid from a
unix group name.

The jack_promiscuous_perms() function adjusts the permissions of a shared
resource (socket, semaphore, shm segment, ...) referenced by a fd and/or a
path so it can be used by any member of the provided unix group.

By using those functions it will be possible to enable a secure promiscuous
mode. 'Secure' meaning here that one is not forced to launch every clients
with a (way) too permissive 0000 umask.
