If someone was still using this...feel free to add it back in with a
comment about why it needs to be in the mainline. It looked better to
remove it than edit it to make sure it worked.

This ioctl is called either via the "/dev/dahdi/channel" file or via a
/dev/dahdi/channo file. In either case, either the minor number of the
device file will match up with a channel, or the "private_data" member
on the channel will be set, so the unit is redundant.

I believe this makes it a little more clear what is happening. Also could
provide a potential speedup if the span doesn't need to be constantly
dereferenced (although an optimizer might make this moot). Regardless, this
change doesn't hurt.

In __dahdi_process_getaudio_chunk and __dahdi_process_putaudio_chunk we
can streamline the operation slightly by saving a constant pointer to
the conference channel instead of constantly dereferencing the master
channel and indexing into the chan array.

It is still used at span registration / unregistration to assign the span
number, and when iterating through all spans. Otherwise, moves the code base a
step closer to removal of the 'spans' array.

Enable DAHDI to detect if an operation on a file handle refers to a
channel that may have been unregistered. This can occur, for example,
when a board driver is hot-swapped out in a live system.
This patch ensures that file->private_data is always properly set for
any open channel, and it's set back to NULL when a channel is
unregistered. This way file->private_data can be used to check whether
it's valid to perform an operation on the channel. (NOTE: There is
still a race condition here if the driver was unbound on one processor
during the window of time between when file->private_data was checked
and the system call finishes).
Also, since DAHDI should only return -ENODEV on read or write when there
was a surprise device removal on a running system this sleep can prevent
the system from becoming unresponsive if the userspace application does
not check for the -ENODEV error and constantly tries to call read with
elevated privileges.

I have yet to personally come across a system where this actually
changes the observable behavior, but it certainly seems like the sane
thing to do and I would rather not let this float around as a patch when
I can just merge it in.

These functions were only defined if BUF_MUNGE was defined, but even if
that symbol is defined there is not anyplace in the driver where these
functions were then called. This has been in the code since rev 87 so
this is most likely stale debugging code.
Feel free to revert if this is actually used somewhere that is not
apparent.
Here is where the functions were originally added to the drivers:

Upon shutdown, both drivers would attempt to power down external
interfaces, but never attempted to bring them back up when the span was
restarted. Removing that code allows the driver to work properly until
a better solution can be found.

dahdi_tool was incorrectly reporting all spans to be in local timing
mode. This is because the driver tracks which span it's timing syncs to,
within the card local struct "wc". We have to manually go through and
copy timing updates to the span local structs because this is what
dahdi_tool actually reads.

This needs some more testing before it's on by default. If the card is
otherwise functioning, these messages may be confusing to the user. If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
