Rework the tests to run on pc86; lots of test fixes for the brk() test, which

was nearly useless; lots of fixes to qemuppc and pc86 sbrk(), which was broken;
change the pc86 console to echo output to the serial port (needed for running
tests on qemu).

Change sbrk() to take an int rather than an intptr_t (following the OpenBSD way

rather than the Linux way; various non-C bits of the ACK assume it takes an
int, so it's cleaner).

ego now builds and is used.
...
This needed lots of refactoring to ego --- not all platforms have ego descr
files, and ego will just crash if you invoke it without one. I think originally
it was never intended that these platforms would be used at -O2 or above.
Plats now only specify the ego descr file if they have one.

Allow pc86 bootloader to boot from more floppy drives.
...
When the bootloader probes the drive geometry, the BIOS can clobber the
es register. If this happens, the bootloader loads the program to the
wrong address, and jumps off the code. This happens with an emulated
floppy drive in Bochs or QEMU, but not with an emulated hard disk.
