Implement IO_NOWDRAIN and B_NOWDRAIN - prevents the buffer cache from blocking
in wdrain during a write. This flag needs to be used in devices whos
strategy routines turn-around and issue another high level I/O, such as
when MD turns around and issues a VOP_WRITE to vnode backing store, in order
to avoid deadlocking the dirty buffer draining code.
Remove a vprintf() warning from MD when the backing vnode is found to be
in-use. The syncer of buf_daemon could be flushing the backing vnode at
the time of an MD operation so the warning is not correct.

- There is no such thing as a socket structure. sockets are integers.
I'm assuming that the comment was regarding socket address structures, so
correct the comment about pre-zero'ing socket structures to recommend
pre-zero'ing socket address structures.

- now that key_debug_level is always defined, there's no need for
#ifdef IPSEC_DEBUG around sysctl MIB code (net.key.debug).
- switch all debug printf() to ipseclog().

Don't pass os_boot_rendez directly to SAL_SET_VECTORS, because it's
actually the address of the function descriptor. The fdesc has both
the address of the function and it's corresponding gp value. Now
that we have a gp value, use it instead of passing 0.
Refer people looking to figure out what major to use for a device to
MAKEDEV and sys/conf/majors, not sys/conf/device.<arch>, which has
never existed in the history of FreeBSD (well, at least it isn't in
the repository).

Add mnt_reservedvnlist so we can MFC to 4.x, in order to make all mount
structure changes now rather then piecemeal later on. mnt_nvnodelist
currently holds all the vnodes under the mount point. This will eventually
be split into a 'dirty' and 'clean' list. This way we only break kld's once
rather then twice. nvnodelist will eventually turn into the dirty list
and should remain compatible with the klds.

Forced commit:
Fix breakage in previous time_t related commit:
quad_t is not a 'long long' - don't use that for casting for printf %lld
(it is plain "long" on our 64 bit platforms).
Also, These timestamps are relative to boot time, not 1970. We dont need
to slow things down here with synthetic types on i386 since we have
other wraparounds that occur *long* before 68 years of uptime.

Fix a bug in CD9660 when vmiodirenable is turned on. CD9660 was assuming
that a buffer's b_blkno would be valid. This is true when vmiodirenable
is turned off because the B_MALLOC'd buffer's data is invalidated when
the buffer is destroyed. But when vmiodirenable is turned on a buffer
can be reconstituted from its VMIO backing store. The reconstituted buffer
will have no knowledge of the physical block translation and the result is
serious directory corruption of the CDROM.
The solution is to fix cd9660_blkatoff() to always BMAP the buffer if
b_lblkno == b_blkno.

Trim all the extra debugging output including hexdumps, debug messages,

the screen and COM1. Also, the twiddle is still disabled since it seems
to do weird things to the serial dump. cdboot now has 880 bytes to spare.

This is a new CD bootstrap utility designed to replace cdldr. According
to the El Torito standard for CD booting, a CD may boot in "No emulation"
mode without using a floppy image. In this mode, the BIOS loads a program
off of the CD into memory and creates a BIOS device using 2048 byte sectors
for the CD. According to the standard, this program can be up to 0xFFFF
virtual (512-byte) sectors long. The old cdldr depended on this by having
the BIOS load the entire loader and the small cdldr stub as one binary
similar to pxeboot so that cdldr didn't have to read the CD to find the
loader. However, the NT no emulation loader just uses 1 disk sector
(4 virtual sectors), so it seems that at least some BIOS writers just did
enough to get NT to boot by only loading 1 sector and ignoring the sector
count. Thus, while cdldr should have worked in theory, it doesn't in
practice. This replacment fits entirely in 1 sector and includes simple
ISO 9660 support. It looks for /boot/loader on the CD and loads it up
using the BIOS. This allows us to not have to depend on the limited size
of floppy images but use a full GENERIC kernel for CD-ROM installs in the
future, among other things.
This version of cdboot is a bit bloated as it includes some useful
debugging routines that people can pull to use in other x86 assembly
modules. Even with all the debugging cruft, we still have 272 bytes to
spare.
