git/{diff,import}: make it easier to handle manually-asembled patch emails
Often, people (including myself) will write emails that
can almost be applied with git/import. This changes
git/diff and git/import so that things will generally
work even when assembling diffs by hand:
1. git/import becomes slightly more lax:
^diff ...
^--- ...
will both be detected as the start of a patch.
2. git/diff produces the same format of diff
as git/export, starting with paths:
--- a/path/to/file
+++ b/path/to/file
which means that the 'ape/patch -p1' used
within git/import will just work.
So with this, if you send an email to the mailing list,
write up a committable description, and append the
output of git/diff to the end of the email, git/import
should just work.
[this patch was send through the mailing list using the
above procedure, and will be committed with git/import
to verify that it works as advertised]

mk for only supported archs
http://fqa.9front.org/fqa1.html#1.2 states the supported archs.
However, clean and nuke also remove build files for 0 (spim) and q

build all the kernels, even those which are not supported. For
example, I tried to build the power arch (qc, qa, ql) and without
surprise it failed (when building dtracy): ...

The patch below skips over non-supported architectures. Is that
something we want? This way, 'mk kernels' should work without a
problem (tested on amd64). Then if someone works on getting those
architectures supported again in the future, they can be added back
in.

snoopy: fix dns nil pointer crashes when formating dns packets (thanks sl)
snoopy shares ndb/dns's dns parser code, but has its own
copy of rralloc() function, which is responsible to allocating
auxiolary data structures on an RR depending on the type.
ndb/dns gained some support for some new types, but snoopy's
copy of rralloc() was not updated, resulting the auxiolary
structures to be nil, and the shared parsing routines crashes
when trying to dereference them.
this just syncs the copies, we might consider moving rralloc()
into its own file so it can be completely shared.

git: better handling of absolute paths, regex metachars
Git currently gets a bit confused if you try to
manipulate files by absolute path. There were also a
number of places where user-controlled file paths ended
up getting passed to regex interpretation, which could
confuse things.
This change mainly does 2 things:
- Adds a 'drop' function which drops
a non-regex prefix from a string, and uses
that to manipulate paths, simplifies 'subst',
and removes 'subst -g', which was only used
with fixed regexes; sed does this job fine.
- When getting a path from a user, we
make it absolute and then strip out the head
Along the way it cleans up a couple of stupids:
- 'for(f in $list) if(! ~ $#f 0) use $f:
$f can't be a nil list because of
list flattening.
- removes a useless substitution here:

git/export: use 'date -f' instead of 'date -m'
The '-m' flag was added to date largely

it's a recent enough addition that nothing
I'm aware of uses it, other than git.

x509: encode empty sequence as constructed

git/fetch: be more robust
currently, git/fetch prints the refs

the packfile has been successfully

arm64: use generic timer virtual counter for cycles()
We used to use performance cycle counter for cycles(),
but it is kind of useless in userspace as each core
has its own counter and hence not comparable between
cores. Also, the cycle counter stops counting when
the cores are idle.
Most callers expect cycles() to return a high resolution
timestamp instead, so do the best we can do here
and enable the userspace generic timer virtual counter.
sbrk(0) returns the current end address of the BSS segment,
not the base. This might have been confused with the behaviour
of segbrk(), which when given a zero address returns the base.

libaml: fix gc bug, need to amltake()/amldrop() temporary buffer
we have to protect the temporary buffer allocated by rwfield()
as rwreg() calls amlmapio() which might cause further aml code
execution causing gc() which frees it under us (as it is not
referenced from the interpreter state).
this fixes a panic on boot of a
Lenovo Thinkpad P17 Gen1 Professional Mobile Workstation
when a virtio device gets reset, we have to also reset the device
shadow indices: availableidx and usedidx. for extra safetly,
we also reset the buffer descriptor table addresses.
this is accomplished by adding a vioqreset(VIOQueue*) function
that brings the queue to its initial reset state.
this fixes non functional ethernet after reboot(8).
virtio: add non-legacy virtio 1.0 drivers for disk and ethernet
The new interface uses pci capability structures to locate the
registers in a rather fine granular way making it more complicated
as they can be located anywhere in any pci bar at any offset.
As far as i can see, qemu (6.0.50) never uses i/o bars in
non-legacy mode, so only mmio is implemented for now.
The previous virtio drivers implemented the legacy interface only
which uses i/o ports for all register accesses. This is still
the preferred method (and also qemu default) as it is easier to
emulate and most likely faster.
However, some vps providers like vultr force the legacy interface
to disabled with qemu -device option "disable-legacy=on" resulting
on a system without a disk and ethernet.
kernel: export pcienumcaps() for custom capability enumeration in drivers (virtio)
This used to be a internal function, but virtio
uses multiple structures with the same cap type
to indicate the location of various register
blocks in the pci bars so export it.

reason, a comma separated list is returned as the certificate subject,
making it symmetric to X509rsareq() handling.

a certificate (or a certificate request when -r flag is provided) and
outputs the RSA public key in plan 9 format appended with the subject
