This moves the celt parts of JackNetTool into JackNetCelt so celt
headers are not undeliberately included from JackNetDriver (which is
compiled without celt).

This moves the opus parts of JackNetTool into JackNetOpus so opus
headers are not undeliberately included from JackNetDriver (which is
compiled without opus).
All opus includes has got the opus/ prefix removed since it is added by
the pkg-config opus file.
Also the netone driver has to be compiled with opus.
Lastly JackNetTool.h needed a header guard.

This assures that the header can be found in a non-standard prefix,
since the leading opus/ is added to the include path by the opus
pkg-config file.

This makes sure header checks work when the third party package is
installed in a non-standard location, as long as a pkg-config file is
found.

Use _WIN32 instead of WIN32 in header files since WIN32 might not alw…

Implement new jack_port_rename API

JACK2 added this function first, but the int return has been always wrong.
When JACK1 added JackPortRenameCallback it used the proper return.

Now that JACK1 supports port renames, devs will start to use it.
(previously it didn't work properly because of the missing jack_client_t* arg)

Some code might be broken because of this, but it's a very simple change,
and existing code would have been broken when changing JACK1 to JACK2.

Finally, JACK2 code never uses the int return value of this callback.
So there's no real reason to NOT change this.

For instance, if compiling with gcc and the option --stc=c++11, WIN32 is not defined.

Correct netmanager latency reporting

Fix buf nullptr dereferencing in jack_midi_event_write()

[jack_bufsize] Fix off by 10 error

Since help and error messages suggest, that 8192 samples is a valid
buffer size, this fixes the value in the check to 8192 instead of 8182.

Fix return value of SetTimebaseCallback()

return value of JackGenericClientChannel->SetTimebaseCallback() instead
of -1 where there is a conditional request

Fix svnversion.h generation
