vmd: Implement simulated baudrate support in the ns8250 module. The
previous version was allowing an output rate that is "too fast", and linux
guests would give up after 512 characters TXed ("too much work for irq4").
This diff calculates the approximate rate we can sustain at the current
programmed baud rate and limits the output to that rate by inserting a
HZ delay after a specified number of characters have been transmitted.
This fixes the linux guest console issue.
Note that the console now outputs at more or less the selected baud rate,
instead of nearly instantaneously as before - if you selected 9600 in
your guest VMs before, you might want to change that to 115200 now for a
better console experience.

Although several codepaths in the kernel such as coredump

Catch up with changes made on amd64 (kettenis@):
Generating mixed 16-bit/32-bit/64-bit code with clang's integrated
assembler is a bit tricky. It supports the .code16, .code32 and
.code64 directives. But it doesn't know about the data16/data32 and
addr16/addr32 instruction prefixes. Instead it tries to determine
those from the instruction opcode. It mostly succeeds, but there are
a couple of corner cases where clang will generate the "addr32" form
where gas generates the "addr16" form in .code16 segments. That
should be no problem (and just waste a couple of bytes), but it makes
comparing the generated code a bit difficult.
Allow the trampoline code to be compiled with both. For clang #define
away the addr32 prefix and avoid using the data32 prefix by using a
mnemonic that explicitly encodes the size of the operand. Add a few
addr32 prefixes in .code16 blocks to reduce the differences between

Be more strict about escape sequences that rename windows or set titles:
ignore any that not valid UTF-8 outright, and for good measure pass the
result through our UTF-8-aware vis(3).

Support SIGUSR2 to stop and start logging for an existing server. Also
we currently only have two log levels so just use -v and -vv rather than
-v and -vvvv, and clarify the man page entry for -v.

Re-arrange struct bus_dmamap members
This reduces holes/padding and makes the struct smaller by 8 bytes.

use htolem32 and lemtoh32 instead of htole32 and letoh32.
saves about half a k on sparc64.

Pure preprocessor implementation of the roff(7) .ec and .eo requests
(escape character control), touching nothing after the preprocessing
stage and keeping even the state variable local to the preprocessor.
Since the escape character is also used for line continuation, this
requires pulling the implementation of line continuation from the
input reader to the preprocessor, which also considerably shortens
the code required for that.
When the escape character is changed, simply let the preprocessor
replace bare by escaped backslashes and instances of the non-standard
escape character with bare backslashes - that's all we need.
Oh, and if anybody dares to use these requests in OpenBSD manuals,
sending a medium-sized pack of axe-murderes after them might be a
worthwhile part of the punishment, but probably insuffient on its own.
