6c96352a06 Remove support for autoloading ACPI from the loader. Leave in the code to 
detect ACPI and export info such as the location of the RSDP via hints as
that is still useful.

4832a19173 Add a "comconsole_speed" loader variable that can be used to change 
the serial console speed (i386 and amd64 only). If the previous
stage boot loader requested a serial console (RB_SERIAL or RB_MULTIPLE)
then the default speed is determined from the current serial port
speed. Otherwise it is set to 9600 or the value of BOOT_COMCONSOLE_SPEED
at compile time.

This makes it possible to set the serial port speed once in
/boot.config and the setting will propagate to boot2, loader and
the kernel serial console.

8b7c03a7a4 - Add support to the loader for multiple consoles. 
- Teach the i386 and pc98 loaders to honor multiple console requests from
  their respective boot2 binaries so that the same console(s) are used in
  both boot2 and the loader.
- Since the kernel doesn't support multiple consoles, whichever console is
  listed first is treated as the "primary" console and is passed to the
  kernel in the boot_howto flags.

4d87b291ad Extend `autoboot_delay' handling - is this variable is set to -1 don't allow 
user to interrupt autoboot process at all. Currently, even when
`autoboot_delay' is set to 0, loader(8) still allows autoboot process to be
interrupted by pressing any key on the console when the loader reads kernel
and modules from the disk. In some cases (i.e. untrusted environment) such
behaviour is highly indesirable and user should not be allowed to interfere
with the autoboot process at all.

bootp -> BOOTP
    bootp.nfsroot -> BOOTP_NFSROOT
    bootp.nfsv3 -> BOOTP_NFSV3
    bootp.compat -> BOOTP_COMPAT
    bootp.wired_to -> BOOTP_WIRED_TO

- i.e. back out the previous commit.  It's already possible to
pxeboot(8) with a GENERIC kernel.

59e1ebc9b5 Change the following kernel options to environment variables: 
BOOTP -> bootp
    BOOTP_NFSROOT -> bootp.nfsroot
    BOOTP_NFSV3 -> bootp.nfsv3
    BOOTP_COMPAT -> bootp.compat
    BOOTP_WIRED_TO -> bootp.wired_to

This lets you PXE boot with a GENERIC kernel by putting this sort of thing
in loader.conf:

    bootp="YES"
    bootp.nfsroot="YES"
    bootp.nfsv3="YES"
    bootp.wired_to="bge1"

or even setting the variables manually from the OK prompt.

84344f9fbf Rename the kern.vm.kmem.size tunable to the more logical vm.kmem_size. To 
assure backward compatibility (conditional on !BURN_BRIDGES), look it up
by its old name first, and log a warning (but accept the setting) if it
was found.  If both the old and new name are defined, the new name takes
precedence.

Also export vm.kmem_size as a read-only sysctl variable; I find it hard to
tune a parameter when I don't know its default value, especially when that
default value is computed at boot time.
