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

Change stdio to use atexit() rather than the internal __clean variable; this

breaks the dependency between exit/atexit and stdio. Buffers are no longer

Realise that the libc core can safely call other libc core functions, even if

they're not defined in the core: so putw() can call stdio stuff, for example.

Don't check ferror(fp) when reading fp.
...
If feof(fp) or ferror(fp) was set, then our libc returned EOF for all
later reads without trying to read. Our libc now behaves like BSD
(and probably Illumos and musl) by checking only feof(fp). For
difference, glibc doesn't check feof(fp).
I described the difference between our libc and BSD libc in
https://sourceforge.net/p/tack/mailman/message/35430300/

Delete unused misc/getpw.c from libc.
...
@hexcoder- reported in https://github.com/davidgiven/ack/issues/57
that our getpw() has bugs.
I don't fix these bugs, because Illumos and Linux manual pages say
that getpw() is obsolete. The function can overflow its buffer, so it
is never safe to use. Our libc did not build getpw().

Delete malloc.h and tgmath.h from libc.
...
This malloc.h might get confused with the private malloc.h in our
libc. C programs should #include <stdlib.h> for malloc().
This tgmath.h has no useful content, and never worked because
complex.h is missing.
Touch build.lua (by deleting some whitespace) so the *.h globs see
the deletions.

Build fdopen(), hypot(), putenv() in libc.
...
These functions are in POSIX; hypot() is in C99. Also build cabs()
because it rides with hypot(), but don't declare cabs() in any header
file, because our compiler can't parse C99 "double complex" type.
Touch build.lua so it sees that .c files moved.

This restores the correct values of DBL_MAX, DBL_MIN_EXP, and related
