It may be that pthreads on NetBSD is now good enough,
but the build as written (introduced in 23a2368 at my suggestion)
is certainly broken, since both NetBSD.c and pthread.c define
the same functions.
If NetBSD does support pthreads now, then a few things
should happen together:
- libthread/sysofiles.sh should drop its top NetBSD case entirely
- libthread/NetBSD.c should be deleted
- libthread/NetBSD-*-asm.s should be deleted
- include/u.h's NetBSD case should define PLAN9PORT_USING_PTHREADS
and #include <pthread.h>
For now, restore to less clearly broken build.
Linux.c was for Linux 2.4 and is no longer used directly,
only indirectly because NetBSD.c was a 1-line file #including Linux.c.
So mv Linux.c NetBSD.c.
Also rm Linux-*-asm.s which was for Linux 2.4 as well.
They were just a duplicate of my(get|set)mcontext from the other
assembly file, and unused from threadimpl.h.

The issue manifests in fork: POSIX fork mandates that a
fork'd process is created with a single thread. If a
multithreaded program forks, and some thread was in
malloc() when the fork() happened, then in the child
the lock will be held but there will be no thread to
release it.
We assume the system malloc() must already know how to
deal with this and is thread-safe, but it won't know about
our custom spinlock. Judging that this is no longer
necessary (the lock code was added 15 years ago) we remove
it.

The dump substitutes each \n in a multiline tag with a 0xff byte.
Since it is not valid UTF it cannot occur in an ordinary dump file.
Old acmes will just read it in as an error rune.

This hides the menu on dock on all screens which is more than we want.
The code was added to fix a problem with Catalina that I can no longer
reproduce, so I guess it works now.
Fixes#336.
There are many things we could do to make this work.
an environment variable to control the character.
Another option would be to use U+00A0 (non-breaking space),
which renders the same as space.
This change avoids changing the separator character and instead
assumes that if the left side of the tag already ends in " Del Snarf |"
then what comes before that is the file name.
Acme already aggressively preserves the "Del Snarf |",
so this should work decently well as a stop-gap.
We can always try something else later.

Real disk devices should be block devices anyway.
One user reported the disksize check causing a
system reboot during vac of a tree with an "interesting"
device.
Fixes#103.
This brings mk's behavior when using rc in line with Plan 9's.
The existing code is for Unix environment data structures but
also was assuming Unix shell semantics where empty and missing
variables are mostly equivalent.
The Plan 9 code (/sys/src/cmd/mk/plan9.c in the distribution)
explicitly removes /env/name (creating an empty list) when the
value is missing or an empty string.
Fixes#255.
Improved error message in case of unexpected open flags. The message
unexpected open flags requested=0100040 unhandled=040
prompted me to clear the FMODE_EXEC flag, although I wonder if I
shouldn't have set OEXEC (0x3) instead.
Now that we only have Metal, we can drop the -metal.
Also now that Carbon is gone we can drop the macargv.c,
and then the -objc from object file names.
We didn't start using Metal until macOS 10.14,
but it was available on 10.13, which is currently
the oldest Apple-supported version of macOS.
Simplify by deleting the old code.
The functions from <ctype.h> require that their argument be
representable as an unsigned char, anything else is an error.

Some truetype fonts have good manual hinting.
Ignoring hinting makes the font render badly on low resolution screens.
This commit only disables the freetype autohinter, and allows hinting.
This splits a certain vtmallocz call in mkihash into two vtmallocz
calls. The first issue this fixes is that the C aliasing rules were not
respected in the code before this commit. The other thing is that this
enables better memory alignment guarantees.

For pthread systems that are fussy about which stack is used,
this makes sure that threadmain runs on a system stack.
If you only use proccreate (never threadcreate), all threads run
on system stacks.
Under certain conditions it looks like frexp gets #defined
to something else on macOS during system headers,
which then breaks the declaration in libc.h.

Remove blank lines from the ends of files.

In general, no space after `if` etc, and no
braces for a single statement inside of a loop
or conditional.

A loop is added for each structure field instead of accessing the other
fields through the first one in one loop.

These make no sense and are not really needed at all.
Add a best-effort attempt to get at the gcc/clang macro
in lib9.h, but if it fails, no big deal.

This should prevent the issues of dist/buildmk and src/mkhdr getting out
of synchronization yet again.
I also add a rule for arm64 to the OBJTYPE sed command.
