On slow platforms, it helps to spread the hashing load
over time so that tftp does not timeout.
Also, some .4th files are too big to fit in cache of pkgfs,
so increase cache size and ensure fully populated.

We must wrap C declarations in __BEGIN / __END_DECLS to avoid C++ name-mangling
of the declaration when including the C header; name-mangling causes the linker

For head/, this will remain eternally default-on to maintain the status quo.
For stable/ branches, it should be flipped to default-off to maintain the
status quo.
There's value in being able to flip it one way or the other easily on head
or stable branches, whether you want to gain some performance back on head/
(for machines there's little chance you'll actually hit an assertion) or
potentially diagnose a problem with the version of llvm on an older branch.
Currently, stable branches get the CFLAGS+= -ndebug line uncommented; going
forward, they will instead have the default of LLVM_ASSERTIONS flipped.

These functions first appeared in the First Edition of Unix (or earlier in the
pdp-7 version). Just claim 1st Edition for all this. The pdp-7 code is too
fragmented at this point to extend history that far back.
Modern debuggers and process tracers use ptrace() rather than procfs
for debugging. ptrace() has a supserset of functionality available
via procfs and new debugging features are only added to ptrace().
While the two debugging services share some fields in struct proc,
they each use dedicated fields and separate code. This results in
extra complexity to support a feature that hasn't been enabled in the
default install for several years.

For this, things are complicated. The first mention in the manual was in the 4th
edition manual (as an add on to exec(II)). The 2nd and 3rd editions didn't have
these in the manual (either as a separate page, or as an add-on to exec(II)). We
don't have good 1st, 2nd or 3rd edition distributions to look in. However,
there's a tape labeled 'last1120c' that we do have. This tape contains the last
version of the V2 edition of the C compiler on it (just after C got struct). On
this tape there was a libc.sa archive that contains source for execl and
execp. This source is sufficiently different from the V5 sources (which are the
next ones we have sources for) and have a slightly different calling convention
than later sources, suggesting that the early date for the last1120c tape is
correct (in that era, the epoch changed every year, leading to a one or two year
ambiguity on when the files could have been modified) and it should be though of
as V2. Since this was also a time of compiler development, and the calling
convetions are known to be under evolution, and since the rest of the sources in
libc.sa are consistent, that's further evidence that V2 is likely. Finally, 2nd
edition was the last version to fully support the 11/20 because it lacked many
basic features and bell labs moved off it to the 11/45 as soon as they could
afford to buy one, around this time era. The unix manuals make it sound like V3
might have supported the 11/20, but the same intro could also be read to mean it
didn't, at all, and that V3 was the first rewrite for the 11/45 ahead of the
rewrite in C that came with V4.
Taken together, the evidence leans most heavily to V2 (90% IMHO), and slightly
to V3 (8%) or possibly V4 (2%). I've not put all this in the man page, but have
left it here in case someone notices in the future that V4 is the first manual
page for it.
In a single-threaded program pthread_getspecific() always returns NULL,

This similarly matches what we do in libc; compiling libssp with
-fstack-protector* is actively harmful. For instance, if the canary ctor
ends up with a stack protector then it will trivially trigger a false
positive as the canary's being initialized.
This was noted by the reporter as irc/ircd-hybrid started crashing at start
after our libssp was MFC'd to stable/11, as its build will explicitly link
in libssp. On FreeBSD, this isn't necessary as SSP bits are included in
libc, but it should absolutely not trigger runtime breakage -- it does mean
that the canary will get initialized twice, but as this is happening early
on in application startup it should just be redundant work.
