123ae3045d build: remove LIBPTHREAD/LIBTHR build options
WITHOUT_LIBTHR has been broken for a little over five years now, since the
xz 5.2.0 update introduced a hard liblzma dependency on libthr, and building
a useful system without threading support is becoming increasingly more
difficult.

Additionally, in the five plus years that it's been broken more reverse
dependencies have cropped up in libzstd, libsqlite3, and libcrypto (among
others) that make it more and more difficult to reconcile the effort needed
to fix these options.

Remove the broken options.

1a05d9519d libcasper/cap_grp tests: Reset the group database handle
Some tests verify that the capgrp capability does not permit calls to
setgrent(3), but all tests need to ensure that they reset the
capability's group database handle, otherwise the local process and
casper process will be out of sync.

The cap_pwd tests already handle this.

5619d49e07 libc/nss: Restore iterator state when doing passwd/group lookups
The getpwent(3) and getgrent(3) implementations maintain some internal
iterator state.  Interleaved calls to functions which do passwd/group
lookups using a key, such as getpwnam(3), would in some cases clobber
this state, causing a subsequent getpwent() or getgrent() call to
restart iteration from the beginning of the database or to terminate
early.  This is particularly troublesome in programming environments
where execution of green threads is interleaved within a single OS
thread.

Take care to restore any iterator state following a keyed lookup.  The
"files" provider for the passwd database was already handling this
correctly, but "compat" was not, and both providers had this problem
when accessing the group database.

85d028223b libthr malloc: support recursion on thr_malloc_umtx.
One possible way the recursion can happen is during fork: suppose
that fork is called from early code that did not triggered
jemalloc(3) initialization yet. Then we lock thr_malloc lock, and
call malloc_prefork() that might require initialization of jemalloc
pthread_mutexes, calling into libthr malloc. It is safe to allow
recursion for this occurence.

5844bd058a jobc: rework detection of orphaned groups.
Instead of trying to maintain pg_jobc counter on each process group
update (and sometimes before), just calculate the counter when needed.
Still, for the benefit of the signal delivery code, explicitly mark
orphaned groups as such with the new process group flag.

This way we prevent bugs in the corner cases where updates to the counter
were missed due to complicated configuration of p_pptr/p_opptr/real_parent
(debugger).

Since we need to iterate over all children of the process on exit, this
change mostly affects the process group entry and leave, where we need
to iterate all process group members to detect orpaned status.

(For MFC, keep pg_jobc around but unused).

d36b5dbe28 libc: regex: rework unsafe pointer arithmetic
regcomp.c uses the "start + count < end" idiom to check that there are
"count" bytes available in an array of char "start" and "end" both point to.

This is fine, unless "start + count" goes beyond the last element of the
array. In this case, pedantic interpretation of the C standard makes the
comparison of such a pointer against "end" undefined, and optimizers from
hell will happily remove as much code as possible because of this.

An example of this occurs in regcomp.c's bothcases(), which defines
bracket[3], sets "next" to "bracket" and "end" to "bracket + 2". Then it
invokes p_bracket(), which starts with "if (p->next + 5 < p->end)"...

Because bothcases() and p_bracket() are static functions in regcomp.c, there
is a real risk of miscompilation if aggressive inlining happens.

The following diff rewrites the "start + count < end" constructs into "end -
start > count". Assuming "end" and "start" are always pointing in the array
(such as "bracket[3]" above), "end - start" is well-defined and can be
compared without trouble.

As a bonus, MORE2() implies MORE() therefore SEETWO() can be simplified a
bit.

VOP_WRITE() functions that understand the new IO_DATASYNC flag can act

behaviour.
