It does not make sense to show a "thread count" column when displaying
threads separately. In fact we don't, but do show the header for this
column. Fix this.
The precision with behavior is "unspecified" by POSIX (as of 2018), but
most implementations seem to have taken it to be treated the same as for
"s"; applied after the unescaping.
Adopt the same treatment on our printf.

We don't generally support the weird case of regular expresions delimited
by an opening square bracket ('[') but POSIX says that inside
bracket expressions, escaping is not possible and both '[' and '\'
represent themselves.

The abidump routine output an ABI tag when -A was specified for records
that were not displayed due to type or pid filtering. To fix, split
the code to lookup the ABI from the code to display the ABI, move the
code to display the ABI into dumpheader(), and move dumpheader() later
in the main loop as a simplification. Previously dumpheader() was
called under a condition that repeated conditions made later in the
main loop.

I inadvertently broke 'wc -L' in r326736. We must skip the fast path if -L
was specified, in addition to the existing check for the -l option.
Document long-standing -L behavior (count varies depending on whether wc(1)
is run with the -m option or not) in wc.1. That behavior dates back to the
introduction of the -L option, but was not documented.

The timespecadd(3) family of macros were imported from NetBSD back in
r35029. However, they were initially guarded by #ifdef _KERNEL. In the
meantime, we have grown at least 28 syscalls that use timespecs in some
way, leading many programs both inside and outside of the base system to
redefine those macros. It's better just to make the definitions public.
Our kernel currently defines two-argument versions of timespecadd and
timespecsub. NetBSD, OpenBSD, and FreeDesktop.org's libbsd, however, define
three-argument versions. Solaris also defines a three-argument version, but
only in its kernel. This revision changes our definition to match the
common three-argument version.
Bump _FreeBSD_version due to the breaking KPI change.

Remove procedural code that did the scanning, which was faulty and didn't
support complex constants such as 0x1p-61. Replace it with a finite state
machine expressed as a transition table. The table was rewritten by hand
from lx's output, given parts of grammar expressed as regular expressions.
lx is Katherine Flavel's lexer generator, currently available at
https://github.com/katef/libfsm and the parts of grammar were taken from
http://quut.com/c/ANSI-C-grammar-l-2011.html and extended to support binary
integer constants which are a popular GCC extension.

Refactor the following code into something that is more clear
and fix signed integer shift, by casting all buf[] elements to
(unsigned int):
unsigned char buf[8];
uint32_t usize;
[...]
else {
usize = buf[4] | buf[5] << 8 |
buf[6] << 16 | buf[7] << 24;
[...]
New version:
usize = buf[4];
usize |= (unsigned int)buf[5] << 8;
usize |= (unsigned int)buf[6] << 16;
usize |= (unsigned int)buf[7] << 24;
Only the "<< 24" part needs explicit cast, but for consistency make the
integer promotion explicit and clear to a code reader.

quatactl(2) mechanism. (Read-only at this point, however.)
In particular, this is to allow rpc.rquotad query quotas
for NFS mounts, allowing users to see their quotas on the
hosts using the datasets.
The changes specifically:
* Add new RPC entry points for querying quotas.
* Changes the library routines to allow non-UFS quotas.
* Changes rquotad to check for quotas on mounted filesystems,
rather than being limited to entries in /etc/fstab
* Lastly, adds a VFS entry-point for ZFS to query quotas.
Note that this makes one unavoidable behavioural change: if quotas
are enabled, then they can be queried, as opposed to the current
method of checking for quotas being specified in fstab. (With
ZFS, if there are user or group quotas, they're used, always.)

Replace size_t members with ksize_t (uint64_t) and pointer members
(never used as pointers in userspace, but instead as unique
idenitifiers) with kvaddr_t (uint64_t). This makes the structs
identical between 32-bit and 64-bit ABIs.
On 64-bit bit systems, the ABI is maintained. On 32-bit systems,
this is an ABI breaking change. The ABI of most of these structs
was previously broken in r315662. This also imposes a small API
change on userspace consumers who must handle kernel pointers
becoming virtual addresses.
