Loss of crc4-multiframe alignment on an E1 link is not a condition which
brings the span down. The span will continue to run as long as it can
maintain double frame alignment. Because of this, we cannot place the
LMFA alarm in the usual spaninfo.alarms member, due to userspace
programs using this as a catch-all for a span being up or down.
We can detect the alarm by watching the frame error counter (fecount).
If it continuously increments, the span is configured for crc4, and the
span remains OK (alarms = 0), then we are in loss of crc4-multiframe
state.
In order to test this alarm, you'll need to synthesize a loss of crc4
alignment on the span. You can usually do this by configuring the local
span to use crc4 and the remote end to not use crc4. I used the Fireberd
6000 in my lab to do this.

astribank_is_starting should use a timeout for the semaphore, but if the
GNU-specific semtimedop() is not available, we'll just fall back to using
semop with no time out. Not as good, but better than nothing.

While slightly less efficient, this is only used when configuring the
channels initially (not the hot path) and allows dahdi-base.c to assume
that the open "file" pointer always refers to the channel on which to
perform the operation.

Module 'dahdi_dummy.ko' is no longer needed for DAHDI to provide timing,
therefore we can remove the explicit load of dahdi_dummy, which by
default is aliased to dahdi.ko anyway. If you've edited the DAHDI
Kbuild file in order to build dahdi_dummy explicitly, then you should
add dahdi_dummy to /etc/dahdi/modules in order to load it, but this is
not needed for normal operation.

Menuselect was originally included in the DAHDI-Tools repository with an svn
external. Since git does not handle externals so well, menuselect is being
brought into the tree directly. This allows menuselect to be present for all the
commits on the 2.4, 2.5, and 2.6 releases.
The command is:
$ svn export http://svn.asterisk.org/svn/menuselect/trunk menuselect
