Upgrade our copies of clang, llvm, lldb and compiler-rt to 3.8.0
release.
Please note that from 3.5.0 onwards, clang, llvm and lldb require C++11
support to build; see UPDATING for more information.
Release notes for llvm and clang will soon be available here:

Signal handling within tcsh vfork code path will conflict with some system
libraries (such as libthr) which maintain their own signal state. This
change adds the tcsh SAVESIGVEC option to save and restore the sigvecs for
the signals the child modifies before it execs.

Add support to enable/disable both the EHCI and OHCI Allwinner clocks. This
adds a lock to ensure only a single device is accessing the hardware. A
reference count is added to only enable when we start to use the clock,
and to disable after we have finished needing the clock.
This was extracted from a larger review to add OHCI support to the
Allwinner SoCs.

Revert r296395.
This mistakenly removed the SUBDIR_PARALLEL but even worse is that the install
(and build) order is not correct due to the lack of SUBDIR_DEPEND on the
most critical libraries. The only reason they build correctly now is because
buildworld's 'make libraries' orders them properly.

Conditionalize building makewhatis(1) for upgrades that need it.
Remove building of the legacy makewhatis(1) since it was only needed for
6.0 upgrades.
On my 2.2 GHz system libsqlite3 takes 60-100 seconds to build, which due to
its serialized nature can hold up the build waiting on it to finish in
bootstrap-tools.
makewhatis(1) was only required to be a build tool to support upgrades
from 6.0 which was properly removed in r208324 but later reverted due to
installworld using it. The installworld issue was fixed in r275622
when it was added to ITOOLS. A BOOTSTRAPPING check was missed when
makewhatis(1) was replaced with mandoc in r283777.

Update libsdp to the latest 1.1.108-0.17.ga6958ef.
The only relevant change here is the support for IPv6 in the config

config. The change for that ended up removing __sdp_sockaddr_to_sdp

NO_ROOT: Create the METALOG directory on installworld/distributeworld.

xdr: Fix xdr_rpc* defines.
The defines for xdr_rpc* in xdr.h are wrong. It could be
very well that Solaris did strip the '_t' from xdr_u_int32_t,
but Solaris has a xdr_u_int32 function, we don't have this.
So all of this defines will lead to an unresolved symbol.
This explains why we do not use these functions in FreeBSD
while they are used in Illumos/Solaris.

elfcopy: fail if debug link target is empty
An empty debug link target previously returned a confusing and incorrect
error like "objcopy: fread failed: No error: 0". Now, return an explicit

GNU objcopy allows an empty file as the debug link target. However,
that case is nonsensical so diverging from GNU behaviour is fine.

Pass MNTK_NO_IOPF and MNTK_UNMAPPED_BUFS flags from the lower
filesystem to the nullfs mount.
MNTK_NO_IOPF must be present on the nullfs struct mount so that struct
file fo_read and fo_write fops operate in the mode requested by the
lower mount.
MNTK_UNMAPPED_BUFS allows VOP_GETPAGES() to use unmapped buffers. It
does not matter for VOP_GETPAGES() calls from vm_fault() since handle
of the vm_object always points to the lower vnode. But it may be

DEBUG_FILES: Create the DEBUGFILEDIR if it doesn't exist on install.
Currently the base.txz distribution does not get the BSD.debug.dist mtree

Replace all resource occurrences of '0UL/~0UL' with '0/~0'.
Summary:
The idea behind this is '~0ul' is well-defined, and casting to uintmax_t, on a
32-bit platform, will leave the upper 32 bits as 0. The maximum range of a
resource is 0xFFF.... (all bits of the full type set). By dropping the 'ul'
suffix, C type promotion rules apply, and the sign extension of ~0 on 32 bit
platforms gets it to a type-independent 'unsigned max'.

If callout_stop_safe() noted that the callout is currently executing,

sleepq_check_timeout() needs to be informed that the callout is

e.g. decrement references from the callout callbacks.
