Encoding-specific processing introduced in r335836 is not recommended.
And doing getenv("LANG") and assuming an encoding based on it is a
very bad practice to internationalize software.

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.

Fix possible strict aliasing issue (if time_t is the same size as int but
not int but for example long) which also resulted in a false positive
warning on systems with 64-bit time_t. Pointer casts are bad; we can just
copy the time_t.
Elsewhere, avoid casting char * to int * by using memcpy().

mode to 'io' mode, an artifact remains because the buffer is not
"finished" with a NULL terminator using sbuf_finish().
An example of this is, when the "m" command is entered, the title line
will contain COMMANDND instead of COMMAND. This commit fixes this.
There isn't any need to limit the size of the screen. Utilities like
'less -S' don't have a (meaningful) limit anyways. This also makes the
way to dynamically changing the column widths based on the screen width.
This code isn't designed to be particularly portable outside of FreeBSD.
To be more specific it doesn't make much sense to support compiling
find(1) on VMS.
This also fixes -mio with 'T' set (thread-id instead of process-id).
This can go further by removing the existing sprintf, and using sbuf
directly. This will be done in a followup commit.
There is no documented reason for this not to be shown on the first run.
I can't find any good reason, and it breaks batch mode.

When the load is "high" (an arbitrary value) top(1) previously moved the
cursor to the top-left of the screen as an acknowledgment. In practice,
on modern machines, even relatively slow ones, it looked more like a
glitch. Remove the logic.
The current header formatting is a giant format string that changes
global state during the format process.
Make the following changes:
- use sbuf to build up the header rather than use the above
pseudo-dynamic one
- Change name length to 10
- Reduce size of RES and SIZE by making humanize more aggressive
- Restore a version number line to the copyright. This may be required
by the copyright (and may not be; its unclear)
This is also a pre-req to implementing TOPCOLOR from newer versions of
top(1)
