- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Fix -Wundef from compiling the amd64 LINT.

Add an include for netinet/ip_compat.h directly so that we don't need to
add another special file in the creation of ioctls.c for kdump.

Merge the changes from 3.4.35 to 4.1.8 into the kernel source tree

Darnit, through a maze of twisty passages, ipfilter needs to have PFIL_HOOKS
defined. Revert part of the previous commit to fix this.

Sprinkle in some __FreeBSD_version checks so that this compiles again. Don't
define PFIL_HOOKS anymore.

Submitted by: keramida

From __FreeBSD_version 600001 on PFIL_HOOKS is permanently in the kernel and
doesn't require to include opt_pfil_hooks.h.

Update ipfilter from 3.4.31 -> 3.4.35. Some important changes:
* block packets that fail to create state table entries
* only allow non-fragmented packets to influence whether or not a logged
packet is the same as the one logged before.
* correct the ICMP packet checksum fixing up when processing ICMP errors for NAT
* implement a maximum for the number of entries in the NAT table (NAT_TABLE_MAX
and ipf_nattable_max)
* frsynclist() wasn't paying attention to all the places where interface
names are, like it should.
* fix comparing ICMP packets with established TCP state where only 8 bytes
of header are returned in the ICMP error.

KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)
