For whatever reason all three of these programs
contain switches like:
switch(x) {
case 1:
if(cond)
case 2:
f();
}
Like Duff's device, this is legal C but more obscure
than it really needs to be.
This commit assumes those are intended as written
and simply writes them more clearly. I did consider
that maybe they are mistakes, but in the case of sam/regexp.c,
my rewrite in this commit matches the acme/regx.c that
has been in plan9port since I added acme in 2003.
(I didn't bother to dig up the old Plan 9 releases.)
Assuming acme/regx.c has been correct for the past
two decades, this commit should be correct too.

Having two locks in the proc was causing deadlocks.

Now that we assume pthreads, the only assembly
left is in libmp and libsec.
We only ever added assembly for 386.
The portable C code is fine for plan9port.

Now that everything uses pthreads and pthreadperthread,
can delete various conditionals, all the custom context code,
and so on. Also update documents.
Fixes #355.

Programs that want to background themselves now need
to define threadmaybackground returning 1.
This avoids a confusing (to people and debuggers)
extra parent process for all the threaded programs
that will never want to background themselves.

I added a direct call from thread.c to pthread.c's _threadpthreadstart
in May, and no one has complained about NetBSD being broken.
So probably no one is using this on NetBSD at all.
Make pthread the only option.

This was causing sporadic but frequent crashes at startup
in 9pserve on the new M1 Macs, correctly diagnosing a
use-after-free.

This should make the AIX build finally work.

Drawing as white on black to produce a mask only works if
the white on black is the inversion of black on white.
Emoji that force use of specific colors don't respect that.
Draw black on white and invert to mask separately.

This fixes https://github.com/9fans/plan9port/issues/436
This doesn't necessarily address the underlying issue: calling p9create with
mode = OREAD should probably be allowed, but currently doesn't work on
OpenBSD.

Unclear why it is here (wkj added it long ago).
It has never been installed into $PLAN9/bin,
so it's doubtful that anyone has ever used it.
Arnold Robbins has an alternate version at
https://github.com/arnoldrobbins/dformat.
Fixes #421.

List mode was constrained to the BMP. This change introduces
the following new list mode convention, using Go string literal syntax:
Non-printing ASCII characters display as \xhh.
Non-ASCII characters in the BMP display as \uhhhh.
Characters beyond the BMP display as \Uhhhhhhhh.

Runes in Plan 9 were limited to the 16-bit BMP when I drew up
the RPC protocol between graphical programs and devdraw
a long time ago. Now that they can be 32-bit, use a 32-bit wire
encoding too. A new message number to avoid problems with
other clients (like 9fans.net/go).
Add keyboard shortcut alt : , for U+1F602, face with tears of joy,
to test that it all works.

ASAN can't deal with the coroutine stacks.
In theory we can call into ASAN runtime to let it know about them,
but ASAN still has problems with fork or exit happening from a
non-system stack. Bypass all possible problems by just having
a full OS thread for each libthread thread. The threads are still
cooperatively scheduled within a proc (in thos mode, a group of OS threads).
Setting the environment variable LIBTHREAD=pthreadperthread
will enable the pthreadperthread mode, as will building with
CC9FLAGS='-fsanitize=address' in $PLAN9/config.
This solution is much more general than ASAN - for example if
you are trying to find all the thread stacks in a reproducible crash
you can use pthreadperthread mode with any debugger that
knows only about OS threads.

Found by ASAN.

getdirentries(2) has been deprecated on macOS since 10.5 (ten releases ago).
Using it requires disabling 64-bit inodes, but that in turn makes binaries
incompatible with some dynamic libraries, most notably ASAN.
At some point getdirentries(2) will actually be removed.
For both these reasons, switch to opendir/readdir.
A little clunky since we have to keep the DIR* hidden away
to preserve the int fd interfaces, but it lets us remove a bunch
of OS-specific code too.
