Merging to the current and testing with other existing multicast routers

subr_diskmbr.c:
Don't "helpfully" enlarge our idea of the disk size to cover all the
primary slices. Instead, truncate or discard slices that don't seem
to be on the disk. The enlargement was a hack for disks that don't
report their size (e.g., MFM disks). It is just wrong in general.
wd.c:
In CHS mode, limit the disk size so that cylinder numbers >= 65536
cannot occur. This normally only affects disks larger than 33.8GB.
CHS mode accesses to addresses above the limit are now properly broken
(an error is returned instead of garbage for reads and disk corruption
for writes).

o Drop all broadcast and multicast source addresses in tcp_input.
o Enable ICMP_BANDLIM in GENERIC.
o Change default to 200/s from 100/s. This will still stop the attack, but
is conservative enough to do this close to code freeze.
This is not the optimal patch for the problem, but is likely the least
intrusive patch that can be made for this.

malloc region (kmem_map) to be wrong and semi-random on systems with more
than 1GB of RAM. This is not a complete fix, but is sufficient for
machines with 4GB or less of memory. A complete fix will require some
changes to the getenv stuff so that 64bit values can be passed around.
NOT FIXED: machines with more than 4GB of RAM (e.g. some large Alphas)
since we're still using ints to hold some of the values.

uhci_check_intr() routine needs to be more careful about deciding when
the end of a transfer has been detected.
This allows me to remove the nasty workaround code from if_aue and if_cue.
Receive performance is now much better for these adapters (500KB/sec
vs. 350KB/sec).
Also removed unused KUE_CUTOFF define from if_kuereg.h.

- Fix btxldr to preserve a NULL bootinfo pointer when it copies the kernel
arguments.
- Add the cdldr bootstrap program. This program is tacked onto the
beginning of the standard 3rd stage boot loader (/boot/loader) to form
the CD boot loader (/boot/cdboot). When a CD is booted, the cdboot file
is copied into memory instead and executed. The cdldr stub emulates the
environment normally provided by boot2 and then starts the loader. This
booting method does not emulate a floppy drive, but boots directly off of
the CD. This should fix the problems some BIOS's have with emulating a
2.88 MB floppy image.
- Add support to the loader to recognize that it has been booted by cdldr
instead of boot2 and use a simpler method of extracting the BIOS boot
device.
of %cr0 wasn't reloaded into %eax before being modified to turn protected
mode off if PAGING was not defined. The result was that the processor did
not exit protected mode, so when it tried to jump to segment 0x0 in the
next instruction to clear the prefetch cache like one should when leaving
protected mode, it actually tried to jump to a null selector, causing a
GPF.
(prefix related ioctl should only be called on router,
because host use dynamic address and prefix configuration mechanism,
and those prefix are managed separately with ones whih are assined

Using recursion to traverse the recursive data structure for extended
partitions was never good, but when slice support was implemented in
1995, the recursion worked for the default maximum number of slices
(32), and standard fdisk utilities didn't support creating more than
the default number. Even then, corrupt extended partitions could
cause endless recursion, because we attempt to check all slices, even
ones which we don't turn into devices.
The recursion has succumbed to creeping features. The stack requirements
for each level had grown to 204 bytes on i386's. Most of the growth was
caused by adding a 64-byte copy of the DOSpartition table to each frame.
The kernel stack size has shrunk to about 5K on i386's. Most of the
shrinkage was caused by the growth of `struct sigacts' by 2388 bytes
to support 128 signals.
Linux fdisk (a 1997 version at least) can now create 60 slices (4 standard
ones, 56 for logical drives within extended partitions, and it seems to
be leaving room to map the 4 BSD partitions on my test drive), and Linux
(2.2.29 and 2.3.35 at least) now reports all these slices at boot time.
The fix limits the recursion to 16 levels (4 + 16 slices) and recovers
32 bytes per level caused by gcc pessimizing for space. Switching to
a static buffer doesn't cause any problems due to recursion, since the
buffer is not passed down. Using a static buffer is wrong in general
because it requires the giant lock to protect it. However, this problem
is small compared with using a static buffer for dsname(). We sometimes
neglect to copy the result of dsname() before sleeping.
Also fixed slice names when we find more than MAX_SLICES (32) slices.
The number of the last slice found was not passed passed recursively.
The limit on the recursion now prevents finding more than 32 slices
with a standard extended partition data structure anyway.
