Increase the number of TX DMA segments from 32 to 35.  It turned
out 32 is not enough to support a full sized TSO packet.
While I'm here fix a long standing bug introduced in r169632 in
bce(4) where it didn't include L2 header length of TSO packet in
the maximum DMA segment size calculation.

Hide CTL messages about SCSI error responses.  Too many users take
them for actual target errors.  They can be enabled back by setting
kern.cam.ctl.verbose=1, or booting with bootverbose.

- In the libiconv module for ISO 2022 restore the original order of the
  fields of a private struct such that variables of this type are
  initialised correctly.  Fixes conversion from ISO 2022.
  Also do this in the BIG5 module to prevent similar errors in the future.
- In the libiconv module for EUC-TW replace 2^cs with 1<<cs.  Fixes
  conversion from EUC-TW.
- Synchronise iconv code with NetBSD.  In most cases this only updates
  the RCS id because the changes are already there or are NetBSD specific.

Add atf m4 files from the vendor branch.

These were originally deleted as "not important" but, actually we need them
in place if we want to be able to use autoconf on software that provides
atf-based tests.  (That includes being able to rebuild autotest from scratch
on the Kyua cluster machines, as the automated setup does.)
Add gpiobus(4) as a link to gpio(4).
