this fixes real-time applications.
-n previously specified a rate divisor rather than the rate itself,
which was used for specific applications outside of 9front. instead,
just set the rate directly, more useful and straightforward.

Remove unused fields and factor common fields into a
new PMach struct in port/portdat.h.
The fields machno, splpc and proc are not moved to
PMach as they are part of the known offsets from
assembly (l.s).

Resample is well known for taking a long time to resize an image. This
patch brings an important performance boost (in my test image, time
was reduced from ~2850ms to ~500ms). It does that by extracting FP
multiplication and division out of the innermost loop of
resamplex/resampley.
The results differ slightly from the current implementation: in my
test: ~0.3% of the bytes had a ±2 difference in their value, which I
attribute to rounding errors. I'm personally not concerned with that
deviation, given the performance gains. However, I recommend testing
it just to be sure I didn't overlook anything.

Unmatched substrings are nil, so we can't rely on nil terminating the
array of substrings.

The patch does the following:
1. Adds recognition of executable script (shebang) files.
2. Returns correct MIME type for mbox files (RFC 4155).
3. Returns XML instead of HTML type in some cases.

devloopback was changed from using #X to #λ awhile ago; one bit was missed.

When an imap fetch fails, it's helpful at times to know the underlying
cause. This provides more details by providing the underlying error
message.

Setting headers from Mail can cause conflicts
with the headers that upas/marshal adds when
sending attachments.
So, let's not set them.

We forgot to update the message count when deleting
messages in mail, meaning we could access trailing
messages that had been freed.

unlike other tools like iconv(1), a crop(1) without arguments or with
ones resulting in a no-op, like `-t 0 0', errors out. other options
like `-i 0' do not error. this breaks assumptions and results in
tedious intermediary steps or hacks like:
foo | {crop -t $1 $2 >[2]/null || cat} > baz.bit
instead, just ignore the check. subsequent code doesn't make
assumptions on that.

The raspberry pi 4 PXE firmware insists on finding the tftp
server address by parsing dhcp option 66 as an ip address
string.

/sys/src/cmd/mksyslib uses `{basename $stem .$objtype}^.c to get the
source file name for *.acid files. /sys/lib/acid/thread expects
sched.$objtype.acid. This lets /sys/src/libthread/mkfile generate
that file.

This patch adds dirmodefmt from fcall.h to pretty-print file
permissions, similarly to ls -l. I didn't notice any performance
degradation.
I hope no-one relied on the old behaviour.

this patch adds a small check to the "iff" function, so this
way file can detect webp files. tested with a webp file i
found randomly.

i have found one bug. when i put glenda in a position like this
i somehow win, but the glenda can escape from there.
in addition, i have changed the games manpage to include more info about glendy.

We can take advantage of the fact that xinit() allocates
kernel memory from conf.mem[] banks always at the beginning
of a bank, so the separate palloc.mem[] array can be eleminated
as we can calculate the amount of non-kernel memory like:
upages = cm->npage - (PGROUND(cm->klimit - cm->kbase)/BY2PG)
for the number of reserved kernel pages,
we provide the new function: ulong nkpages(Confmem*)
This eleminates the error case of running out of slots in
the array and avoids wasting memory in ports that have simple
memory configurations (compared to pc/pc64).
