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.

First stage in modularising FILE*. Refactor so that printf/scanf don't rely on

Include more headers to declare functions.
...
This causes clang to give fewer warnings of implicit declarations of
functions.
In mach/pdp/cv/cv.c, rename wr_int2() to cv_int2() because it
conflicts with wr_int2() in <object.h>.
In util/ack, rename F_OK to F_TRANSFORM because it conflicts with F_OK
for access() in <unistd.h>.

Raise _XOPEN_SOURCE from 500 to 700
...
In OpenBSD, _XOPEN_SOURCE 500 forces _POSIX_C_SOURCE down to 199506,
which hides the declarations of openat() and fdopendir() and causes
compiler warnings.
Don't set _POSIX_C_SOURCE, because _XOPEN_SOURCE may set
_POSIX_C_SOURCE to a different value.
