if RTLD_NODELETE isn't POSIX, it is widely deployed: at least linux,
freebsd, dragonfly, netbsd, solaris, illumos, apple, and fuchsia have
it.

about shared resources which no program should see. only a few pieces of
software use it, generally poorly thought out. they are being fixed, so
mincore() can be deleted.

libs have it, it is a function that is considered harmful, so:
Delete malloc_usable_size(). It is a function that blurs the line
between malloc managed memory and application managed memory and
exposes some of the internal workings of malloc. If an application
relies on that, it is likely to break using another implementation
of malloc. If you want usable size x, just allocate x bytes. ok

While it is not clear (to me) why that ports ends up with corrupted
shared libs, reverting those changes fixes the issue and should allow us
to close p2k17 more smoothly.

on the stack instead of mallocing the list and move the APIs from libpthread
to libc so that they can be used inside libc.
Note: the standard was explicitly written to permit/support this
"macro with unmatched brace" style and it's what basically everyone
else already does. We xor the info with random cookies with a
random magic to detect/trip-up overwrites.
Major bump to both libc and libpthread due to the API move.

src/lib/libc/gen/tree.c is a copy of src/sys/kern/subr_tree.c, but with
annotations for symbol visibility. changes to one should be reflected
in the other.
the malloc debug code that uses RB code is ported to RBT.
because libc provides the RBT code, procmap doesn't have to reach into
the kernel and build subr_tree.c itself now.

This stores errno, the cancelation flags, and related bits for each thread
and is allocated by ld.so or libc.a. This is an ABI break from 5.9-stable!
Make libpthread dlopen'able by moving the cancelation wrappers into libc
and doing locking and fork/errno handling via callbacks that libpthread
registers when it first initializes. 'errno' *must* be declared via
<errno.h> now!
Clean up libpthread's symbol exports like libc.
On powerpc, offset the TIB/TCB/TLS data from the register per the ELF spec.

move their definitions and initialization in static links to libc.a
Make crt0 always invoke a new func _csu_finish() in libc to process the auxv
and to either register the ld.so cleanup function (in dynamic links) or
initialize environ and __progname and do MC_DISABLE_KBIND (in static links).
In libc, get pagesize from auxv; cache that between getpagesize() and
sysconf(_SC_PAGESIZE)

thrkill(2), rolling the kill(2) syscall number with the ABI change to
avoid breaking binaries during during the transition. thrkill(2) includes
a 'tcb' argument that eliminates the need for locking in pthread_kill()
and simplifies pthread_cancel(). Switch __stack_smash_handler() to use
thrkill(2) and explicitly unblock SIGABRT.
Minor bump to both libc and libpthread: make sure you install a new kernel!
