This reverts commit dde9f29a8e.

The commit introduced the following compiler error:

[100/255] Compiling posix/JackNetUnixSocket.cpp
../posix/JackNetUnixSocket.cpp: In member function 'int Jack::JackNetUnixSocket::NewSocket()':
../posix/JackNetUnixSocket.cpp:126:32: error: 'tos' was not declared in this scope
         socklen_t len = sizeof(tos);

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 unix sockets when promiscuous mode is enabled.

This doesn't seem necessary since it is implmented below

Crash was observed in this function when fSemaphore was NULL, this patch
copies the NULL pointer check from the commented function above into
Wait()

Space required before macro. No functional changes.

allow autostart of jackd on OSX where device-names can
contain spaces.

Original patch by

 Luciano Montanaro <luciano.montanaro@magnetimarelli.com>

A few internal source files were redeclaring types and macros also
declared in the external jack/types.h and jack/systemdeps.h headers.
Since the external header needs them, delete them from the internal
headers.
