GCC: Add a new option "-fstack-protector-strong"
This includes additional functions to be protected: those that
have local array definitions, or have references to local frame
addresses. This is a new option in GCC-4.9 that was relicensed
by Han Shen from Google under GPLv2.

Correct naming of sysctl pmtud_blackhole_activated_min_mss.
Clarify some statements around PMTUD blackhole detection to make
the behavior more clear in the man page.
When compiling on -current from r284356 to r285986, the host's
crunchgen can't be used because builds of rescue break when STRIP= was
used to prevent stripping of binaries. Direct commit because -current
code is different. Building 10 on current is common enough to warrnat
a safety belt since this has been broken for two months. The offending
change was never in stable/10.
Since the case where secflavor < 0 indicates the security flavor is
to be negotiated, it could be a Kerberized mount. As such, filling
in the "principal" argument using the canonized host name makes sense.
If it is negotiated as AUTH_SYS, the "principal" argument is meaningless
but harmless.
libusb: Fix minor warning.
Fix a warning triggered by the gcc + FORTIFY_SOURCE patches:
In function 'libusb20_parse_config_desc': lib/libusb/libusb20_desc.c:141:
warning: passing argument 1 of 'memcpy' discards qualifiers from pointer
target type

This is a direct commit to 10-STABLE - 11-CURRENT is not affected,
because tunables are automatically fetched there.

Build debug version of rmlock's methods only when LOCK_DEBUG > 0.
Currently LOCK_DEBUG is always defined in sys/lock.h (0 or 1).
This means that debugging code always built. In addition the kernel
modules have always defined LOCK_DEBUG as 1. So, debugging rmlock code
is always used by kernel modules.
MFC r284918:
Add helper fill_based_sd(9).
MFC r284919:
Add x86 PT_GETFSBASE, PT_GETGSBASE machine-depended ptrace requests to
obtain the thread %fs and %gs bases. Add x86 PT_SETFSBASE and
PT_SETGSBASE requests to set the bases from debuggers. The set
requests, similarly to the sysarch({I386,AMD64}_SET_FSBASE), override
the corresponding segment registers.
MFC r284965:
Document x86 machine-specific ptrace(2) requests.
MFC r285011:
Disallow a debugger on 64bit system to set fs/gs bases of the 32bit
process beyond the end of the process address space.
MFC r285104:
Grammar and language fixes.
- Avoid lock contention in the if_transmit callback by using trylock and
enqueueing the frames when it fails. This way there is some latency
removed from the transmitting path.
- If IFF_DRV_OACTIVE is set (and also if IFF_DRV_RUNNING is not) just
enqueue the desired frames and return successful transmit. This way we
avoid to return errors on transmit side and resulting in
possible out-of-order frames. Please note that IFF_DRV_OACTIVE is set
everytime we get the threshold ring hit, so this can be happening quite
often.

r273544 (MFC in r273921) changed the -f option allow no arguments in vt
mode (used to reset the font back to the default), but broke the
optionality of the size argument for syscons. Drop the required argument
from syscons' optstring for -f so the optional argument handler works
the same way for both syscons and vt.

r284988:
cxgbe(4): request an automatic tx update when a netmap tx queue idles.
The NIC tx queues already do this.
r285220:
cxgbe(4): Do not override the the global defaults for congestion drops.
The hw.cxgbe.cong_drop knob is not affected by this change because the
driver sets up congestion drop on a per-queue basis.
r285221:
cxgbe(4): Add a new knob that controls the congestion response of netmap
rx queues. The default is to drop rather than backpressure.
This decouples the congestion settings of NIC and netmap rx queues.
r284445:
cxgbe(4): Add the ability to dump mailbox commands and replies. It is
enabled/disabled via bit 0 of adapter->debug_flags (which is available
at dev.t5nex.<n>.debug_flags).
r286107:
cxgbe(4): initialize debug_flags from the kernel environment.
