'hypotl_near_underflow' would fail to compile on platforms where long
doubles weren't 80 bit, like on x86. Disable this particular test on

o unit-tests: use private TMPDIR to avoid errors from other users
o avoid strdup in mkTempFile
o always use vfork
o job.c: do not create empty shell files in jobs mode
reduce unnecessary calls to waitpid
o cond.c: fix debug output for comparison operators in conditionals
This adjusts the factor used to scale the subnormal numbers, so it
becomes the right value after adjusting its exponent. Thanks to Steve
Kargl for finding the most elegant fix.
Also enable the hypot tests, and add a test case for this bug.

The basic issue here is that grep, when given -m 1, would stop all
line processing once it hit the match count and exit immediately. The
problem with exiting immediately is that -A processing only happens when
subsequent lines are processed and do not match.
The fix here is relatively easy; when bsdgrep matches a line, it resets
the 'tail' of the matching context to the value supplied to -A and
dumps anything that's been queued up for -B. After the current line has
been printed and tail is reset, we check our mcount and do what's
needed. Therefore, at the time that we decide we're doing nothing, we
know that 'tail' of the context is correct and we can simply continue
on if there's still more to pick up.
With this change, we still bail out immediately if there's been no -A
flag. If -A was supplied, we signal that we should continue on. However,
subsequent lines will not even bothere to try and process the line. We
have reached the match count, so even if the next line would match then
we must process it if it hadn't. Thus, the loop in procfile() can
short-circuit and just process the line as a non-match until
procmatches() indicates that it's safe to stop.
A test has been added to reflect both that we should be picking up the
next line and that the next line should be considered a non-match even
if it should have been.

The null pattern semantics were terrible because I tried to match gnugrep,
but I got it wrong. Let's unwind that:
- The null pattern should match every line if neither -w nor -x.
- The null pattern should match empty lines if -x.
- The null pattern should not match any lines if -w.
The first two will stop processing (shortcut) even if additional patterns
are specified. In any other case, we will continue processing other
patterns. If no other patterns are specified beside a null pattern, then
we match if neither -w nor -x or set and do not match if either of those
are specified.
The justification for -w is that it should match on a whole word, but the
null pattern deos not have a whole word to match on.
Empty pattern files should never match anything, and more importantly, -v
should cause everything to be written.

This includes improvements to the atf-sh helper functions that
significantly reduce the number of spawned processes for each test
and therefore speeds up running the testsuite noticeably.
OpenSSL BIO classes provide an abstraction for dealing with I/O.
OpenSSL provides BIO classes for commonly used I/O primitives backed
by file descriptors, sockets, etc. as well as permitting consumers
of OpenSSL to define custom BIO classes.
One of the methods BIO classes implement is a control method invoked
by BIO_ctrl() for various ancilliary tasks somewhat analgous to
fcntl() and ioctl() on file descriptors. According to the BIO_ctrl(3)
manual page, control methods should return 0 for unknown control
requests.
KTLS support in OpenSSL adds new control requests. Two of those new
requests are queries to determine if KTLS is enabled for either
reading or writing. These control reuquest return 1 if KTLS is
enabled and 0 if it is not.
serf includes two custom BIO classes for wrapping I/O requests from
files and from a buffer in memory. These BIO classes both use a
custom control method. However, this custom control method was
returning 1 for unknown or unsupported control requests instead of 0.
As a result, OpenSSL with KTLS believed that these BIOs were using
KTLS and were thus adding headers and doing encryption/decryption in
the BIO. Correcting the return value removes this confusion.

Merge commit 740a164de from llvm git (by Richard Smith):
PR46377: Fix dependence calculation for function types and typedef
types.
We previously did not treat a function type as dependent if it had a
parameter pack with a non-dependent type -- such a function type depends
on the arity of the pack so is dependent even though none of the
parameter types is dependent. In order to properly handle this, we now
treat pack expansion types as always being dependent types (depending on
at least the pack arity), and always canonically being pack expansion
types, even in the unusual case when the pattern is not a dependent
type. This does mean that we can have canonical types that are pack
expansions that contain no unexpanded packs, which is unfortunate but
not inaccurate.
We also previously did not treat a typedef type as
instantiation-dependent if its canonical type was not
instantiation-dependent. That's wrong because instantiation-dependence
is a property of the type sugar, not of the type; an
instantiation-dependent type can have a non-instantiation-dependent
canonical type.

PR46637: Fix handling of placeholder types in trailing-return-types.
Only permit a placeholder type in a trailing-return-type if it would
also have been permitted in the decl-specifier sequence of a
corresponding declaration with no trailing-return-type. The standard
doesn't actually say this, but this is the only thing that makes sense.
Also fix handling of an 'auto' in a trailing-return-type in a parameter
of a generic lambda. We used to crash if we saw such a thing.

determine the length of the routing table buffer. As of 81728a538d
wpa_supplicant is started before the routing table has been populated
resulting in the length of zero to be returned. This causes
wpa_supplicant to loop endlessly. (The workaround is to kill and restart
wpa_supplicant as by the time it is restarted the routing table is
populated.)
(Personally, I was not able to reproduce this unless wlan0 was a member of

[PowerPC] Do not emit HW loop when TLS var accessed in PHI of loop
exit
If any PHI nodes in loop exit blocks have incoming values from the
loop that are accesses of TLS variables with local dynamic or general
dynamic TLS model, the address will be computed inside the loop.
Since this includes a call to __tls_get_addr, this will in turn cause
the CTR loops verifier to complain. Disable CTR loops in such cases.

This reverts commit 89e3d5671b.
As pointed out, there are several problems with that commit:
1. The new semantics, while useful for clients where multiple
threads use separate contexts, breaks clients which correctly
share a single one
2. Change in semantics would require a library version bump
3. It doesn't build with GCC
