in the driver. This would result in -EBUSY returns from the
DAHDI_TC_ALLOCATE ioctl.
- Increase the length of the receive descriptor ring from 8 to 32 to reduce
the probability of running out of receive descriptors.

checking tool. some of these fixes are non-optimal (casting 'unsigned long' to '__user void *'), but are unavoidable in many cases. started from tzafrir's patch, did most of the work myself.

- When a command is to be retried, turn off the TX_COMPLETE flag before
resubmitting it to the hardware. This should elimate some of the warnings
printed to the kernel log in the wctc4xxp_transmit_cmd function.

memory, but the end results is that operation is more reliable on more
systems.

- In dahdi_transcode.c, Embed the identifiation number, assigned sequentially
when the transcoders are registered, in the transcoder structure. This allows
DAHDI_TC_GETINFO to work as expected even though the transcoders are rotated
on the list in order to spread the load.
- In wctc4xxp, fix bug where all transcoders are named tc400b0.

driver which breaks backwards compatibility.
Basically, I've replaced the memory mapped interface with a read/write
interface that allows codec_dahdi to communicate with the hardware transcoder
the exact size of the packet to be transcoded. This eliminates issues with
remote devices that send G729.B CNG packets even though asterisk does not
support them.
From a user standpoint:
- The transcoder drivers are much more robust in light of system / external
conditions.
From a developer standpoint:
- DAHDI_TRANSCODE_OP is no longer supported, instead use DAHDI_TC_ALLOCATE,
DAHDI_TC_GETINFO, and write/read.
- Memory and stack usage is reduced (stack usage could still be reduced some
more by continuing the process of getting rid of the users of
wctc4xxp_send_cmd and wctc4xxp_create_cmd).
- If more than one card is in the system channels will be allocated in a
round-robin fashion from all available cards, reducing contention for the
supervisor channel.
- There is no longer a tc400b workqueue created that will not show up in the
process list.
- Commands and their responses are now explicitly matched up which elimated
certain errors caused by unsolicited messages from the transcoder confusing
the driver.
- There is now an option to export a network interface for capturing traffic
to/from the hardware transcoder.
- codec_test has been removed from the dadhi/linux package.

also includes a bunch of minor Makefile improvements, and relocating the firmware directory to the directory where the modules live, since that is the only place it is needed
still left to do: handle version.h creation when in native-kernel-tree mode, fix up lots of problems left with firmware file handling
