Bump shlib for dialog because ABI has changed when version 1.2 was imported

Add a new "-o" option to the gssd which forces gss_init_sec_context()
to use DES and the associated old style GSS initialization token.
This appears to be required for some non-FreeBSD servers to
get a kerberized NFS mount to work. Also, ignore some signals when daemonized,
which might fix the gssd from "disappearing" without leaving a core dump.
Given the tight timeframe for the FreeBSD9.2 release, I have
committed this while waiting for code review. I will commit
changes recommended by the review in a separate commit.

When RX checksum offloading is active, AX88772B will prepend a
checksum header.  The header contains a received frame length but
the defined length for AX88772B is different with other ASIX
controllers.  When the RX checksum is off, AX88772B controller does
not prepend a checksum header so driver has to use normal header
length mask.
This change should fix RX errors when RX checksum offloading is
off.

Typo in comment.
Disable hw.pci.realloc_bars by default.  It wasn't needed for the original
tester of this fix, and realloc_bars breaks some other cases as a small
BAR that is reallocated can end up grabbing space needed by a much larger
BAR in the existing window of a PCI-PCI bridge.

gcc: add some configuration and references.

-Add configure support for FreeBSD 10 and 11.
-Adapt a threading fix to gnu POSIX95 (which we don't use).
-Refer to a bug fix for the disabled vrptree support.

This is all useless in our current build but it is included
for convenience in case someone may want to re-package our
older gcc.

This avoid pollution on the busy mechanism and offers a more

Due to the routing related networking kernel redesign work
in FBSD 8.0, interface routes have been returened to the
applications without the RTF_GATEWAY bit. This incompatibility
has caused some issues with Zebra, Qugga and the like.
This patch provides the RTF_GATEWAY flag bit in returned interface
routes so to behave similarly to pre 8.0 systems.
