Patch by Thomas Brand <tom@trellis.ch> and in accordance with jackd1
code base.

ffado_streaming_set_period_size() is exposed starting r2078 of FFADO.
To avoid a build dependency on ffado-svn in jack, we copy the prototype
declaration.

Since the symbol is defined as weak, no problems arise at runtime.

Cleanup of obsolete code, the functionality is now provided
by UpdateLatencies().

This is a port of Jonathan Woithe's patch from jackd1.
With sufficiently recent versions of FFADO, it allows to change
the buffersize at runtime.

In preparation for the upcoming FFADO buffersize functionality,
add code that updates the latency afterwards.

fixes compilation on linux

The main goal is to reduce risk of mismatch between allocated
and initialized parameter numbers.

Update server control API with jackctl_server_open and jackctl_server_close (see http://trac.jackaudio.org/ticket/219 for rationale).  Update drivers to support Start/Stop of slave drivers.  Update dbus to use new jackctl_server_* functions.  Freewheel driver is no longer an implicit slave of the master audio driver.  Haven't tested freewheeling, and didn't update Solaris OSS driver.  Tested slave addition by adding loopback driver, but don't have a slave driver in this branch on Linux platform to test with.

Added MIDI queues, FFADO objects, etc. - see 'http://trac.jackaudio.org/ticket/187' for more details

Improve backend error handling: fatal error returned by Read/Write now cause a Process failure (so a thread exit for blocking backends). Recoverable ones (XRuns..) are now treated internally in ALSA, FreeBob and FFADO backends.
