Support for warnings about missing prototypes in C++ was added by Apple
GCC (Radar 6261539). Most of the code crept into r260311 so it felt
natural to make use of it.

The VMCS field EOI_bitmap[] is an array of 256 bits - one for each vector.
If a bit is set to '1' in the EOI_bitmap[] then the processor will trigger
an EOI-induced VM-exit when it is doing EOI virtualization.
The EOI-induced VM-exit results in the EOI being forwarded to the vioapic
so that level triggered interrupts can be properly handled.

Don't use nopl in cpus that don't support it.
Patch by Mikulas Patocka. I added the test. I checked that for cpu names that
gas knows about, it also doesn't generate nopl.
The modified cpus:
i686 - there are i686-class CPUs that don't have nopl: Via c3, Transmeta
Crusoe, Microsoft VirtualBox - see
https://bbs.archlinux.org/viewtopic.php?pid=775414
k6, k6-2, k6-3, winchip-c6, winchip2 - these are 586-class CPUs
via c3 c3-2 - see https://bugs.archlinux.org/task/19733 as a proof that
Via c3 and c3-Nehemiah don't have nopl

which cause EINVAL returned from nanosleep() which cause loop in
cron_sleep() and making all cron jobs to start about 30 seconds earlier
(which cause f.e. logfiles rotation by newsyslog delayed by 1 hour).
Use simple and proved calculations from kernel's timespecsub() instead.

require tests in order to build or install. Crucially, don't try to
install tests during the lib32 install phase. This commit supersedes
r261081, which fixed the lib32 install phase problem, but didn't fix
other phases.

Add the space to avoid alias recursion when the alias is expanded, not when
it is added.
As a result, displaying an alias via command -v, command -V or type no
longer erroneously appends a space. Adjust the tests so they now require
this bug to be absent.
The limitation was introduced in r178556 without any note or comment.
It seems pretty artificial and now it leads to problems like the following:
$ dtrace -x bufsize=17m -n ...
dtrace: processing aborted: Memory allocation failure
OpenSolaris and illumos never had this limitation.

The IN_* flags should be set in i_flag instead of corrupting
i_flags [1].
Re-enable HTree dirindex as the last series of bug fixes
seems to have fixed the issues.

macro was changed. Since copying 64-bit srr1 into 32-bit srr1 drops the upper
32 bits, any bits set in the context were dropped, meaning the context check
fails. Since 32-bit set_context can't change those bits anyway, copy the ones
from the current context (td->td_frame) before calling set_context().
