Fortunately the consequences of this bug weren't severe; for duplicated
entries in the typedef names file it would unnecessarily duplicate strings

Fix translation of the PrintScreen/SysRq and Pause/Break keys. Almost
everything was broken. The cases that I noticed were Ctrl-PrintScreen
not being mapped to the virtual scancode 0x5c (debug) and Pause not being
mapped to the physical/virtual scancode 0x46 (slock).
These keys are the most complicated ones due to kludges to give some
compatibility back to before AT keyboards.
Alt-PrintScreen must pretend to be a separate key from PrintScreen
even at the "raw" level. The (unique) usb code for it is 0x8a and we
just have to map this to our unique virtual scancode 0x54, but we
mapped it first to the internal code 0x7e and then to 0x79 which is a
key on the Japanese 106/109 keyboard. This fix is under the
UKBD_EMULATE_ATASCANCODE option which shouldn't be used for non-AT
keyboards. If it is, then the syscons Japanese keymaps have nothing
of importance for code 0x79 and can easily be changed. 0x54 is also
unimportant in Japanese and US keymaps.
NonAlt-PrintScreen and NonCtl-Pause/Break had many much larger bugs with
smaller compatibility problems from fixing them. The details are too
ugly to give here. Summary of the changed (hex) codes:
K_RAW PrintScreen (Ctl, Shift, Ctl-Shift): E0-2A-E0-37 -> E0-37
K_RAW Alt-PrintScreen (all shift states): 79 -> 54
K_RAW Pause/Break (unshifted, Shift, Alt, Alt-Shift)): E0-46 -> E1-1D-45
K_CODE ALT-PrintScreen (all shift states): 79 -> 54
That is 15 of 32 shift combinations for 2 keys fixed, with 8 easy cases
from the 79 -> 54 remapping.
The difference is only large and with no workaround using a keymap for
for K_RAW, but this affects other modes when ukbd is layered under kbmux
because kbmux keeps all subdevices in K_RAW mode and translates. Oops.

Rewrite the vDSOs for CloudABI in assembly.
The reason why the old vDSOs were written in C using inline assembly was
purely because they were embedded in the C library directly as static
inline functions. This was practical during development, because it
meant you could invoke system calls without any library dependencies.
The vDSO was simply a copy of these functions.
Now that we require the use of the vDSO, there is no longer any need for
embedding them in C code directly. Rewriting them in assembly has the
advantage that they are closer to ideal (less useless branching, less
assumptions about registers remaining unclobbered by the kernel, etc).
They are also easier to build, as they no longer depend on the C type
information for CloudABI.

[mips] add support for the "creative" GNU extensions and IRIX hilarity around MIPS LO16/HI16 relocations.
This was .. an interesting headache.
There are two halves:
* The earlier IRIX stuff (yes, early) occasionally would do dead
code removal and generate multiple consecutive LO16 entries.
If this is done for REL entries then it's fine - there's no
state kept between them. But gcc 5.x seems to do this for
RELA entries.
eg:
HI1 LO1 HI2 LO2 LO3 HI4 LO4
.. in this instance, LO2 should affect HI2, but LO3 doesn't at all
affect anything. The matching HI3 was in code that was deleted
as "dead code".
Then, the next one:
* A "GCC extension" allows for multiple HI entries before a LO entry;
and all of those HI entries use the first LO entry as their basis
for RELA offset calculations.
It does this so GCC can also do dead code deletion without necessarily
having to geneate fake relocation entries for balanced HI/LO RELA
entries.
eg:
HI1 LO1 HI2 HI3 HI4 LO4 LO5 HI6 LO6 LO7
in this instance, HI{2,3,4} are the same relocation as LO4 (eg .bss)
and need to be buffered until LO4 - then the RELA offset is applied
from LO4 to HI{2,3,4} calculations.
/And/, the AHL from HI4 is used during the LO4 relocation calculation,
just like in the normal (ie, before this commit) implementation.
Then, LO5 doesn't trigger anything - the HI "buffer" is empty,
so there are no HI relocations to flush out.
HI6/LO6 are normal, and LO7 doesn't trigger any HI updates.
Tested:
* AR9344 SoC, kernel modules, using gcc-5.3 (mips-gcc-5.3.0 package)
Notes:
* Yes, I do feel dirty having written this code.

Permit disabling net.inet.udp.require_l2_bcast in VIMAGE kernels.
The default value of the tunable introduced in r304436 couldn't be

via the VNET_NAME() macro, which resolves to the (should-be) read-only

Fix for pr24346: arm asm label calculation error in sub
Some ARM instructions encode 32-bit immediates as a 8-bit integer
(0-255) and a 4-bit rotation (0-30, even) in its least significant 12
bits. The original fixup, FK_Data_4, patches the instruction by the
value bit-to-bit, regardless of the encoding. For example, assuming
the label L1 and L2 are 0x0 and 0x104 respectively, the following
instruction:
add r0, r0, #(L2 - L1) ; expects 0x104, i.e., 260
would be assembled to the following, which adds 1 to r0, instead of
260:
e2800104 add r0, r0, #4, 2 ; equivalently 1
The new fixup kind fixup_arm_mod_imm takes care of the encoding:
e2800f41 add r0, r0, #260

This fixes label calculation for ARM assembly, and is needed to enable
