to be included into this one. This works the same way as #include
does in C; as far as the user is concerned, the included file is
inlined into the current one.
Since config(8) is no longer limited to working on one user-supplied
file, printing just a line number in an error message is not
sufficient. The new global variable yyfile represents the file
currently being parsed, and must be printed as well.

to use 0xffffffff (INADDR_NONE) as a netmask value. The fix
is to use inet_addr(3) which doesn't suffer from this problem.
PR: bin/28873
Also, while here, fixed the bug when netmask value was ignored
(RTF_HOST flag was set) if the "destination gateway netmask"
syntax is used, e.g. ``route add 1.2.3.4 127.1 255.255.255.255''.
'dwatch'. The new commands install hardware watchpoints if supported
by the architecture and if there are enough registers to cover the
desired memory area.

We originally had it such that if the connection topology was FL-loop
(public loop), we never looked at any local loop addresses. The reason
for not doing that was fear or concern that we'd see the same local
loop disks reflected from the name server and we'd attach them twice.
However, when I recently hooked up a JBOD and a system to an ANCOR SA-8
switch, the disks did *not* show up on the fabric. So at least the
ANCOR is screening those disks from appearing on the fabric. Now, it's
possible this is a 'feature' of the ANCOR. When I get a chance, I'll
check the Brocade (it's hard to do this on a low budget).
In any case, if they *do* also show up on the fabric, we should
simply elect to not log into them because we already have an
entry for the local loop. There is relatively unexercised code
just for this case.

1) Bite the bullet, and allow unaligned accesses without buffer copies
on the i386 platform. According to some tests run by Andrew Gallatin,
the buffer copy performance hit is greater than the unaligned access
performance hit (especially with jumbo frames). We still need to copy
everywhere else.
2) Enable interrupt moderation with a 100us timeout.

directories. When enabled via "options UFS_DIRHASH", in-core hash
arrays are maintained for large directories. These allow all
directory operations to take place quickly instead of requiring
long linear searches. For now anyway, dirhash is not enabled by
default.
The in-core hash arrays have a memory requirement that is approximately
half the size of the size of the on-disk directory file. A number
of new sysctl variables allow control over which directories get
hashed and over the maximum amount of memory that dirhash will use:
vfs.ufs.dirhash_minsize
The minimum on-disk directory size for which hashing should be
used. The default is 2560 (2.5k).
vfs.ufs.dirhash_maxmem
The system-wide maximum total memory to be used by dirhash data
structures. The default is 2097152 (2MB).
The current amount of memory being used by dirhash is visible
through the read-only sysctl variable vfs.ufs.dirhash_maxmem.
Finally, some extra sanity checks that are enabled by default, but
which may have an impact on performance, can be disabled by setting
vfs.ufs.dirhash_docheck to 0.

- When both SC_PIXEL_MODE and SC_NO_FONT_LOADING are defined,
quietly drop SC_NO_FONT_LOADING, because the pixel(raster)
console requires font.
- When SC_NO_FONT_LOADING is defined, force SC_ALT_MOUSE_IMAGE.
Without font, the arrow-shaped mouse cursor cannot be drawn.
- Fiddle and simplify some internal macros.
