Kernel version 3.16+, since upstream commit (7f7f25e82d54870d "replace checking
for ->read/->aio_read presence with check in ->f_mode" )[1], does not like it
when dahdi changes the set of allowed file operations on a file descriptor
outside of the context of an open() system call.
DAHDI changes the available file operations when a channel is opened by first
opening /dev/dahdi/channel and then calling the DAHDI_SPECIFY ioctl to bind it
to a particular DAHDI channel. Until DAHDI_SPECIFY is called there weren't any
read()/write() callbacks implemented and therefore after the initial open, the
kernel was setting not setting FMODE_CAN_{WRITE,READ} on the file descriptor
indicating that those operations were not allowed.
Now define empty shell functions on the general dahdi_fops so the vfs layer will
not mark a file descriptor as unwritteable or unreadable on open.

This is because the driver only updates the alarm state when the framer reports
that the span alarm has changed. Therefore, unless the framer goes through an
alarm transition, the fact that channels are opened was never noticed by alarm
handling routine.

This closes a reference and memory leak when multiple CPUs are enabling echocan
on a single channel in parallel.
The essential problem is that the call to try_module_get() is not serialized.
Two separate threads can come into ioctl_echocan() on the same channel, they
coordinate via the dahdi_chan.lock to release any current echocan, but then both
create a new echocan state, bump the reference on the module, and the last one
through will actually attach the new state to the channel. The earlier reference
/ memory is leaked.
I tried to conceive of a way to fix this leak without adding a new lock, but the
choices where calling throught the function pointers with dahdi_chan.lock.
Otherwise I needed to change the semantics of echocan_create /free which would
ripple through the hardware echocan modules.

The driver will now automatically reload the firmware when there are no open
channels if the firmware reports a fatal error. If the firmware reports an
error, but it was not fatal, it will leave things running and try to reload when
all channels are shut down. The driver will also halt channel processing and
reload the firmware if a channel ever failed to be created.
The thought is that if the DTE reports a non-fatal error, I cannot be certain
what the state is, and it should be reset when possible without impacting
otherwise functioning card. If there are problems, presumably all users would
hang up and the driver will then reload the firmware.
If the error is fatal, then all processing is halted to encourage everyone to
hang up. The card is probably not working at this point anyway, so there is no
point in trying to communicate with it.
Also included in this change is a compile-time selectable debug sysfs attribute
that will allow forcing an alert condition for testing the recovery.

Now the driver will silently drop any "burst" traffic that was sent to the
