Initialize and destroy the struct proc mutex in the proc zone's init and
fini routines instead of in fork() and wait(). This has the nice side
benefit that the proc lock of any process on the allproc list is always
valid and sched_lock doesn't have to be used to test against PRS_NEW
anymore.

Instead of recording the Unix time in a process when it starts, record the
uptime. Where necessary, convert it back to Unix time by adding boottime
to it. This fixes a potential problem in the accounting code, which would
compute the elapsed time incorrectly if the Unix time was stepped during
the lifetime of the process.

Add a mechanism to allow Makefiles to specify the particular C dialect
in which the source code is written. This is controlled by the CSTD
variable, which can have one of the following values:
- "k&r" => -traditional
- "c89" or "c90" => -std=iso9899:1990
- "c94" or "c95" => -std=iso9899:199409
- "c99" => -std=iso9899:1999
The corresponding option is added to CFLAGS regardless of WARNS level.
This also removes -ansi from WARNS level 6, but adds -Wno-long-long to
work around a weird gcc bug (-ansi, which is supposedly equivalent to
-std=iso9899:1990, seems to turn long long warnings off instead of on)
If CSTD is undefined, CFLAGS are unchanged except for the -ansi /
-Wno-long-long change mentioned above for WARNS level 6.

The -t flag in the retired apmconf.8 is the same as "-h false" in the
apm.8. Since the -t flag in the apm.8 is something different entirely,
the reference to -t was quite confusing. Fix that.

Do not attempt to free NULL dinodes (i_din1 or i_din2) in ffs_ifree().
These fields can be left as NULL if ffs_vget() allocates an inode but
fails before the dinode memory has been allocated. There are two cases
when this can occur: when we lose a race and another process has added
the inode to the hash, and when reading the inode off disk fails.
The bug was observed by Kris on one of the package-building machines.
See http://marc.theaimsgroup.com/?l=freebsd-current&m=105172731013411&w=2
In Kris's case, it was the bread() that failed because of a disk error.
The alternative to this patch is to ensure that ffs_vget() does not call
vput() when the inode that hasn't been properly initialised.

I'm pleased to announce that Promise is now supporting the FreeBSD
project by providing documentation (under NDA) and hardware for
testing. This commit is the first result of the cooperation, and
adds support for several of their new controllers that we didn't
support before (and probably newer would have without this arrangement).
Add support for the Promise SATA150 TX2/TX4 and the Promise TX4000
controllers. This also adds support for various motherboard fitted
Promise SATA/ATA chips.
Note that this code uses memory mapped registers to minimize overhead.
I belive FreeBSD has made another first in the Open Source world
by being able to release support for this :)

Fix compile errors on ia64 in dagetcapacity. Set block_len and maxsector
to 0 initially. It seems that the ia64 backend isn't as "smart" as the
i386 backend, which realized that those variables were only set or used
when error == 0, and thus were not used uninitialized.

I changed the numbering of the MODINFOMD_SMAP during the commit, so

Enable the i386 loader to load and run an amd64 kernel. If this puts
things over floppy size limits, I can exclude it for release builds or
something like that. Most of the changes are to get the load_elf.c file
into a seperate elf32_ or elf64_ namespace so that you can have two
ELF loaders present at once. Note that for 64 bit kernels, it actually
starts up the kernel already in 64 bit mode with paging enabled. This
is really easy because we have a known minimum feature set.
Of note is that for amd64, we have to pass in the bios int 15 0xe821
memory map because once in long mode, you absolutely cannot make VM86
calls. amd64 does not use 'struct bootinfo' at all. It is a pure loader
metadata startup, just like sparc64 and powerpc. Much of the
infrastructure to support this was adapted from sparc64.

Slight reorg and added AMD64 support. A couple of the MODINFOMD_* values
that were added to sparc64 and later powerpc, really should have been in
the MI area. But changing that now with insufficient preperation will
just cause too much pain.
Move MD_FETCH() to the MI sys/linker.h file to avoid another two copies
of it.
