a131085a5b cd boot workaround for bioses that didn't want to boot >4 image sectors.
boot is a normal binary with a.out again. use 'cdbootblock,' a CDBOOT
variant of bootblock, both from bootblock.s, as the first boot image
that then loads boot, exactly like the bootblock loads boot when booting
from harddisk. the sector numbers (2048 byte iso sectors) are patched in
by writeisofs, like installboot does for bootblock. bootblock unchanged.

477b616fe8 Fixed a number of complaints about missing return statements.
Some cases were fixed by declaring the function void, others were fixed
by adding a return <value> statement, thereby avoiding potentially
incorrect behavior (usually in error handling).
Some enum correctness in boot.c.

daca9de450 Fix to make making a bootable cd possible again.
ow that the image has grown beyond the 1.44M that fits on a floppy.
(previously, the floppy emulation mode was used for cd's.)

the boot cd now uses 'no emulation mode,' where an image is provided on
the cd that is loaded and executed directly. this is the boot monitor.

in order to make this work (the entry point is the same as where the
image is loaded, and the boot monitor needs its a.out header too) and
keep compatability with the same code being used for regular booting, i
prepended 16 bytes that jumps over its header so execution can start
there.

to be able to read the CD (mostly in order to read the boot image),
boot has to use the already present 'extended read' call, but address
the CD using 2k sectors.

ba91b3b7d2 - remove unused bootdelay feauture
- only print a line for every boot process if 'verbose' variable set to
   nonzero; reason: with serial output, the long output
   significantly slows down frequent reboots, and causes 'scroll damage'
   that in some cases is pretty bad. also the verbose output doesn't tell
   you the one thing you might want to know about a process: how much memory
   is it using? or how much memory is everything using?
 - short format does print out total memory allocated for processes
