Probe for BIOS supported disks.
Use BIOS to get geometry for supported disks.
All in preparation to passing the whole thing
to the kernel.

- switch baud rates using i/o instead of bios, since bios commands
have only a limited bitwidth for baudrate, and max out at 9600
- when switching console devices, print msg to both old device and new
- fix timeout bug in com_getc() (dev | 0x80 was reading gobbledygook)
- document 'stty' command in boot(8)
- wording and cleanup in man pages

Adapt to new console probing and setting API. Do not try to probe pc0 via
the NVRAM. Fix some other buglets.
|
|
move time_print() into libsa.h
|
|
|
|
do inline BIOS calls
|

strncmp prototype in stand.h
|
|
com prototypes changes
some indentation
|
|
Parse and convert to seconds since epoch. Please
test, there is a new command "time", which should
print the current time (according to the BIOS) on
the console.

problem with marginal disks. This code does not
like them at all. I'm too frazzled right now to
figure this out. This should give better error
messages...

including:
- disklabel support;
- better boot cmd line
- smaller size (using some compilation switches ;)
- no more relocations in /boot, it's loaded in the place;
- better disk performance (maybe were already in there)
- installboot -n does not require write perms for device
- more debugs
- missing parts in libsa (such as cd9660 and so)
- i don't like 2 files for exec_i386 (sorry, toby, let's discuss maybe?)
tricks and tails:
- joined .text and .data (saves you a page)
- prot mode switching still in biosboot (it's freezed for awhile)
- biosdisk internals changed
- biosdev is not passed propery to the kernel (i'll fix it soon)
- sure i missed smth here to note (use the source, Luke!)
