bf4919e46b Update Digium copyright on files changed since beginning of the year.
In addition to updating the year, this also adds some boilerplate to
dahdi-sysfs.c and dahdi-sysfs-chan.c that wasn't there previously.

fc1824fd3c Remove support for kernels < 2.6.18
This patch removes support for kernel versions < 2.6.18, as those are
not actively supported in any major Linux distribution (except RHEL4,
which is in the "extended" support level of the product life cycle).

This removes much of the more #ifdef-rich parts of the code.

5475f33f3d wct4xxp: VPM module creates noise on alternate channels on E1 spans.
The VPMOCT128 module was using the VPMOCT256 timeslots assigments which would
mean that channels that should be marked alaw were being set in ulaw. This
only affected E1 spans since by default all spans are configured for ulaw by
default.

This fixes a regression introduced in r10290 [1] "wct4xxp: Add support for
TE820 and VPMOCT256", first released in 2.6.0, that only affects E1 spans on a
quad and dual-span card when used with the hardware echocanceler.

11d8140b23 wct4xxp: Add support for TE820 and VPMOCT256.
TE820 is an 8-span PCI-express digital interface card. VPMOCT256 is a hardware
echo canceler that is able to provide echo cancelation on all 8-spans.

86519d1211 Remove unused variables.
gcc-4.6 now warns about variables that are set but never used. Clean up
unused variables everywhere except the oct612x subdirectory.

The oct612x should go in a separate patch in case that needs to be
pulled out into a separate project again.

b0a9e6f31d wct4xxp: Do not lock interrupts while loading the VPM firmware.
Since the oct6100 API consumes less stack there is no longer a danger of
overflowing our stack during load.

c9e258b9b0 wct4xxp: Reduce the memory footprint of the hardware echocanceler.
This saves ~300K of kernel memory for each quad or dual span VPM.  Due
to the fact that this change disables caching of the NLP words (among
other things), the time to disable the echocans appears to have
increased by ~1ms.

bf3fe05dfb wct4xxp: Moving the transmit short detection behind debug module param.
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.
