Further to r240152 (i386) and r240178 (amd64), hide the .cerror symbol
so that it is not exported if symbol versioning is not in use. Without
this change WITHOUT_SYMVER libc contains .text relocations for .cerror,
as described in LLVM PR 26813 (http://llvm.org/pr26813).
This is a no-op for the regular build as the symbol version script
already controls .cerror visibility.

Code may still be executing from the wrappers at unload time and thus is
not generally safe to unload. Converting the wrappers to use
EVENTHANDLER(9) will allow this to safely drain on active threads in
hooks. More work on EVENTHANDLER(9) is needed first.

- Get the list of registers to read during a regdump from the shared
code instead of the OS specific code. This follows a similar move
internally. The shared code includes the list for T6.
- Update cxgbetool to be able to decode T5 VF, T6, and T6 VF register

strlcpy(3) null terminates but does not zero-fill the buffer, so would
leave beind any portion of the previous volume label longer than the
new one.
Note that tunefs only allows -L args up to a length of MAXVOLLEN-1, so
the stored label will be null-terminated (whether or not required by
UFS).

stack is not compliant with RFC 7323, which requires that TCP stacks send
a timestamp option on all packets (except, optionally, RSTs) after the
session is established.
This patch adds that support. It also adds a TCP signature option to the
packet, if appropriate.

Undo update of libedit 2016-02-27
Something in libedit appears to be causing breakage in lldb38.

the boot loader should not skip over these anymore while loading images.
Otherwise the kernel can still panic when it doesn't find the .eh_frame
section belonging to the .rela.eh_frame section.
Unfortunately this will require installing boot loaders from sys/boot
before attempting to boot with a new kernel.

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.

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.

The only relevant change here is the support for IPv6 in the config
file. The previous version of this supported IPv6 but not in the
config. The change for that ended up removing __sdp_sockaddr_to_sdp
which the IPV4 config code required; the IPv6 fix resolved the lack of
that symbol.
Note that the ChangeLog was lacking entries for which we already had the
changes for, which itself was an upstream bug.

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.

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

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
