e502abe001 games/gb: various HDMA fixes
H-blank DMA should only transfer 16 bytes per h-blank, rather than
waiting for the first h-blank and then transferring the whole size.

HDMAC should read 0xff when the transfer is finished, and 0 in the
high bit when the transfer is ongoing. Also, if 0 is written in the
high bit, the current transfer should be aborted.

Introduce two flags, DMAREADY and DMAHBLANK rather than special
constants 1 and -1. If dma is non-zero, there is an ongoing DMA. If
DMAREADY is set, the next chunk is ready to transfer.

Reference: https://gbdev.io/pandocs/#ff55-hdma5-cgb-mode-only-new-dma-length-mode-start

Tested with pokemon crystal.

What was happening is that when the game was loading N background tiles
into vram (each 16 bytes, so one per h-blank), it did something like
this:
- start an hdma transfer for N+1 tiles
- after the Nth tile is transferred, it would read HDMA5, clear the
high bit, then write it back to abort the transfer.

games/gb would instead transfer all N+1 tiles at once, overwriting one
extra tile with whatever was 1 past the end of the source array, and
then would interpret the cancel request as the start of a new transfer
of 16 bytes, which would copy an additional tile past the end. The end
result is that every transfer would end up copying N+2 tiles instead
of just N, overwriting certain tiles with whatever was after the end
of the source data.

655170c873 games/gb: fix timer divider for input clock 0
According to [0], input clock 0 should divide by 1024=2¹⁰, not 2¹².
This caused audio to run at quarter-speed in one game I tried.

827bf1b7da [9front] upas/vf: install %τ format specifier
upas/vf was converted to use tmdate, but the formatter was never
installed.  This caused it to send attachments to validateattachment
with header `From virusfilter %τ%`, which always failed since upas/fs
would just skip over the message.

efcfdd23d7 bcm64: get inbound and outbound pci window base address from device tree
On the pi400, the xhci reset firmware mailbox request
assumes that the pci windows match the ones specified
in the device tree. The inbound window (pcidmawin)
also varies now depending on the amount of memory
installed.

It is all pretty ridiculous, as the firmware could as
well just read the pci controllers hardware register
to determine the window configuration and the os could
keep a nice simple 1:1 mapping (with pci dma addresses
== physical addresses).

b562b269ce test: fix expression parser
The old parser code was rubbish and only worked for trivial
expressions.  The new code properly handles complex expressions,
including short circuit evaluation.

As such, the BUGS section has been removed from the test(1) man page.
The description of an unimplemented feature has also been removed.

49d7ca8d92 runq: clean up code, fix error handling.
Runq spawns a number of processes, and wait()s for them
in 2 different places. Because of the way that the exit
handling is done, the wait can get the wrong message.

It turns out that only one place in the code needs to
wait for the child, and in all other cases, it's just
muddling the problem.

This change adds the RFNOWAIT call to all the processes
we don't need to wait for, so that the places that do
need wait will always get the correct child.

319e625be0 screenlock: use initdisplay(2), top the window (thanks stuart morrow)
Screenlock should use libdraw(2) to init the display
and create the window, instead of looking at the screen
file directly. Also, to prevent new windows from popping
up over screenlock, bring it to the top periodically.

5b8b5884f4 5l: fix shifts by zero
on arm32, we can do one of 4 shifts
by a constant:

	reg<<(0..31)
	reg>>(1..32)
	((u32int)reg)>>(1..32)
	reg ROT (0..31)

There's no way to encode a 0 bit right
shift,  so when encoding reg>>0, flip
it to the equivalent nop reg<<0, which
can be encoded.

f321298c55 upas/runq: support parallel queue processing, drop -a
When running a mail queue, it's useful to run it with limited
parallelism. This helps mailing lists process messages in a
reasonable time.

At the same time, we can remove the load balancing from runq,
since the kinds of systems that this matters on no longer
exist, and running multiple queues at once can be better
done through xargs.

6a78bb2e4f stats: don't query battery and temp as often when using acpi
Querying battery (or temperature) using ACPI takes quite some
resources, which makes the battery discharge faster.  It doesn't make
much sense to have it queried as often either.  So, when using ACPI:

1) set battery query period to 10s minimum
2) set temperature query period to 5s minimum

1047b53efc ape/libap: fix _startbuf, check rfork return (thanks pixelherodev)
When _startbuf is invoked, it would crash on the second invocation
if creating a mux segment failed. This is because the first attempt
would assign the return value -1 to the global mux variable, and
the second attempt would notice that the global mux was not nil,
and would attempt to use it.

This change only assigns to the global variable if the allocation
of the segment was a success.

While we're here, we should also check the return of the rfork call.

cb7ba0e640 dd: error with invalid size suffixes, add 'm'
When invoking with dd with an invalid size suffix, we
silently accept the suffix. This can lead to confusion,
because lines like:

	dd -bs 1K
	dd -bs 1m

will silently copy in 1-byte increments. This has caught
people by surprise. While we're at it, megabytes are
convenient, so let's have them too.
