Some byte shaving; lseek returns the offset.

First at-least-slightly working version of the CP/M read/write stuff. Not as

bad as I expected, but far too big.

Partially working port of stdio to CP/M. I'm not sure this will work; it's
...
getting way too complicated (stdio is horribly subtle). I think I need to
rethink things.

Miscellaneous byte shaving; you can now choose whether or not you want the CCP

overwritten or not, and cpm_exit() does the right thing.

Extend the CP/M libsys with a full set of (hopefully correct) 2.2 BDOS calls.

Create a basic and probably wrong common unistd.h, which replaces the plat one.

Made this work with cpm (but nothing else yet).

Enable the line editor in read() for CP/M.
...
This changes the BDOS call from CPM_BDOS_CONSOLE_INPUT to
CPN_BDOS_READ_CONSOLE_BUFFER. This allows commands like ^H to delete
characters and ^C to exit to CCP. This is more like how Unix read(2)
uses canonical mode of termios to read a line.
This change has a disadvantage: the user buffer to read(2) must now be
large enough for an entire line. This is because CP/M, unlike Unix,
lacks a kernel buffer to hold the rest of the line. If you use a
buffered input library like stdio to call read(2), then it works; but
if you try to read part of a line or a single character, then it
doesn't work.

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).
