Jay Fenlason ce82d255ef Fix reporting of isochronous transmit cycles on firewire-core 
While firewire-core's iso reception ABI was fixed in its version 2 to
report the cycle of each received packet to userspace like rawiso does,
this same enhancement was forgotten to add to the iso transmission ABI,
causing FFADO to fail to set up and maintain streaming.

Since kernel commit 31769cef2e973544164aa7d0db2e2024660d5e21, we also
get iso xmit cycles in fw_cdev_event_iso_interrupt.header.  Pass these
to the iso receive handler.  In case of older kernels, calculate cycles
based on the cycle of the iso interrupt event.  These are inaccurate but
better than nothing.

				   libraw1394
				   ==========

1. About libraw1394

	libraw1394 is the only supported interface to the kernel side raw1394 of
the Linux IEEE-1394 subsystem, which provides direct access to the connected
1394 buses to user space.  Through libraw1394/raw1394, applications can directly
send to and receive from other nodes without requiring a kernel driver for the
protocol in question.

	The reason for making a library the interface to the kernel is to avoid
a program dependancy on the kernel version, which would hinder development and
optimization of raw1394.  If development changed the protocol and made it
incompatible with previous versions only the libraw1394 has to be upgraded to
match the kernel version (instead of all applications).


2. Copyleft

	libraw1394 itself is licensed under the Lesser General Public License
(short LGPL, see file COPYING.LIB in the source distribution).  Other files in
the source archives not belonging to but being part of the build procedure of
libraw1394 are under their own licenses, as stated at the top of the individual
files.


3. API documentation

	Finally there is something, in the doc subdirectory.  The file is
libraw1394.sgml (it's Docbook format), and there are preformatted PostScript and
HTML available.  This documentation is not complete yet.


4. Multithreading

	This library should be multithreadable with the restriction that one
raw1394handle_t may be used only within a single thread.  Multiple threads
operating on the same handle would royally mess up the kernel-user protocol.
Simply use separate handles for each thread in which you need to use libraw1394.


5. Pkg-config

	The library comes with a pkg-config .pc file, so you can check for
libraw1394 and its version in your configure script.  For example, here is how 
to use the autoconf macro:

PKG_CHECK_MODULES(LIBRAW1394, libraw1394 >= 1.1.0)

	This macro sets the variables LIBRAW1394_CFLAGS and LIBRAW1394_LIBS.  You 
have to include those into your build variables so that the build process 
correctly links with libraw1394.


6. Maintainer

	Maintainer of libraw1394 is currently Dan Dennedy.  Send 
suggestions, bug reports and fixes to linux1394-devel@lists.sourceforge.net.
