8918bd5981 acme: implement 'scratch' ctl command (thanks Drew DeVault)
The new command marks the target window as a scratch window -- a window
whose state cannot be "dirtied" by changes made to its body, therefore
avoiding warnings about unsaved changes when deleting the window or
exiting acme.

Existing examples of scratch windows are error, directory, and guide
windows, whose scratchness is set internally.

With the new command users and programs alike can create their own
scratch windows.  This is put to use in acme's own win(1).

a48b462e44 rc: avoid forking for final command that has variable assignments (to get $apid right)
basically, we want the following commands to print
the same pid twice:

rc -c 'cat /dev/pid &;echo $apid'

vs:

rc -c 'a=1 cat /dev/pid &;echo $apid'

basically, Xsimple() calls exitnext() to determine if
a simple command should be promoted to exec, by peeking
ahead into the code and searching for Xexit instruction.

Xexit might not follow immediately after the Xsimple
instruction because of redirections, which exitnext()
would skip.

but it would not skip the Xunlocal instructions that
where added by the variable assignment.

9960a125a3 awk: fix race condition with sub-mk in mkfile
the maketab helper program was generated in parallel, which
had a dependency to y.tab.h which lead to yacc running
twice in parallel.

this removes the dependency to y.tab.h in the virtual
maketab.$objtype target to prevent this race condition.

the dependency to y.tab.h is resolved in the main mk at the
$cputype.maketab target which serializes with the other
targets.

b86bb35c7d pc, pc64: do page attribute table (PAT) init early in cpuidentify()
the page attribute table was initialized in mmuinit(), which is
too late for bootscreen(). So now we check for PAT support and
insert the write-combine entry early in cpuidentify().

this might have been the cause of some slow EFI framebuffers on
machines with overlapping or insufficient MTRR entries.

0002fd0cf7 libc/arm64: work arround linker bug for cas()
at the _cas0 label, the linker would generate spurious stack
adjustment before the return:

atexitdont+0x84 0x000000000003614c	CLREX	$0xf
atexitdont+0x88 0x0000000000036150	MOVW	R31,R0
atexitdont+0x8c 0x0000000000036154	MOV	(SP)16!,R30 <- ????????????
atexitdont+0x90 0x0000000000036158	RETURN

the work arround is to move the code into its own cas0
text symbol.

this fixes impossible cwfs crashes in srvi().

78aec6d5c6 Fix scans of more than one character in %[]

first mismatch; we want to return 0 only when we consumed no
characters.

ed4645979c stop fiddling with path construction.
There's fd2path, which gives back the full path directly.

d332f8a9b5 fix yacc crash with absolute paths
When passing an absolute file path to yacc, we would skip
initializing inpath, leaving it null. This would cause Bopen
to die. We would similarly fail to report an error if we tried
to get the current working directory, and then die when
constructing inpath.

This fixes both cases.

ecdf3f921e ?l: remove direct hunk manipulation from linkers, just call malloc()
as with recent changes, cc's malloc() could make the hunk pointer
misaligned. in the the compilers, the hunk pointer is used directly
by the lexer with no effort to to keep the hunk pointer aligned.

alloc/malloc still return aligned pointers, but hunk itself can
be on a odd address after allocation of a odd sized amount of bytes.

however, in the linkers, this assumption appears to be differnet. as
most allocations mostly allocate padded structures. however, symbol
lookup allocates strings on byte-size ganularity and the cc's malloc
would misalign the hunk pointer after the malloc() call. while the
rest of the code assumed hunk pointer was always aligned.

this change removes all the hunk pointer fiddling from the linker,
and we just call malloc() (which will use the fast implmenentation
of cc, and should not really make much of a performance difference).

73f38fc546 [ape] add missing conversion flags for scanf
We're missing type flags for:

	hh: char
	ll: vlong
	z:  size_t
	t:  ptrdiff_t
	j:  intmax_t

The lack of '%lld' was causing us to fail when parsing
timezone files. This brings us in line with the specifiers
in the C99 standard, section 7.19.6.2p11

27fc79b04b devip: fix ifc recursive rlock() deadlock
ipiput4() and ipiput6() are called with the incoming interface rlocked
while ipoput4() and ipoput6() also rlock() the outgoing interface once
a route has been found. it is common that the incoming and outgoing
interfaces are the same recusive rlocking().

the deadlock happens when a reader holds the rlock for the incoming interface,
then ip/ipconfig tries to add a new address, trying to wlock the interface.
as there are still active readers on the ifc, ip/ipconfig process gets queued
on the inteface RWlock.

now the reader finds the outgoing route which has the same interface as the
incoming packet and tries to rlock the ifc again. but now theres a writer
queued, so we also go to sleep waiting four outselfs to release the lock.

the solution is to never wait for the outgoing interface rlock, but instead
use non-queueing canrlock() and if it cannot be acquired, discard the packet.

c474179f9a usbxhci: fix wrong control endpoint 0 output device context address
the calculation for the control endpoint0 output device context
missed the context size scaling shift, resulting in botched
stall handling as we would not read the correct endpoint status
value.

note, this calculation only affected control endpoint 0, which
was handled separately from all other endpoints.

bfc8cdfff5 fix '%[]' specifiers and '%n' (thanks phil9)
When a match() fails, we need to unget the character we
tried to match against, rather than leaving it consumed.

Also, we can't break out of a conversion before we reach
the end of a format string, because things like the '%n'
conversion do not consume anything, and should still be
handled.

758edf2b14 nusb/kb: add quirks for Elecom HUGE trackball
As said in the code comment:

	Elecom trackball report descriptor lies by
	omission, failing to mention all its buttons.
	We patch the descriptor with a correct count
	which lets us parse full reports. Tested with:
		Elecom HUGE (M-HT1DRBK, M-HT1URBK)

The descriptor fixup is adapted from Linux kernel:
	drivers/hid/hid-elecom.c
in which a more detailed account of why and how this
works may be found.

A followup change to nusb/kb will be needed to expose
these additional events for potential remapping.
