Fix bugs in termios library and cleanup code
This change fixes an issue with the tcflow() magic numbers that was
causing bash to freeze up on Linux. While auditing termios polyfills,
several other issues were identified with XNU/BSD compatibility.

Out of an abundance of caution this change undefines as much surface
area from libc/calls/struct/termios.h as possible, so that autoconf
scripts are less likely to detect non-POSIX teletypewriter APIs that
haven't been polyfilled by Cosmopolitan.

This is a *breaking change* for your static archives in /opt/cosmos if
you use the cosmocc toolchain. That's because this change disables the
ioctl() undiamonding trick for code outside the monorepo, specifically
because it'll lead to brittle ABI breakages like this. If you're using
the cosmocc toolchain, you'll need to rebuild libraries like ncurses,
readline, etc. Yes diamonds cause bloat. To work around that, consider
using tcgetwinsize() instead of ioctl(TIOCGWINSZ) since it'll help you
avoid pulling every single ioctl-related polyfill into the linkage.

The cosmocc script was specifying -DNDEBUG for some reason. It's fixed.

# SYNOPSIS
#
# Freestanding Hermetically-Sealed Monolithic Repository
#
# REQUIREMENTS
#
# You can run your programs on any operating system, but you have
# to build them on Linux 2.6+ (or WSL) using GNU Make. A modern C
# compiler that's statically-linked comes included as a courtesy.
#
# EXAMPLES
#
# # build and run everything
# make -j8 -O
# make -j8 -O MODE=dbg
# make -j8 -O MODE=opt
# make -j8 -O MODE=rel
# make -j8 -O MODE=tiny
#
# # build individual target
# make -j8 -O o//examples/hello.com
# o//examples/hello.com
#
# # view source
# less examples/hello.c

# # view binary
# o//tool/viz/bing.com o//examples/hello.com |
# o//tool/viz/fold.com
#
# # view transitive closure of legalese
# o//tool/viz/bing.com -n o//examples/hello.com |
# o//tool/viz/fold.com
#
# # basic debugging
# make -j8 -O MODE=dbg o/dbg/examples/crashreport.com
# o/examples/crashreport.com
# less examples/crashreport.c

# UNSPECIFIED PREREQUISITES TUTORIAL
#
# A build rule must exist for all files that make needs to consider in
# order to build the requested goal. That includes input source files,
# even if the rule is empty and does nothing. Otherwise, the .DEFAULT
# rule gets triggered.
#
# This is a normal and neecssary behavior when source files get deleted.
# The build reacts automatically to this happening, by simply deleting
# and regenerating the dependency graph; so we can safely use wildcard.
#
# This is abnormal if it needs to keep doing that repeatedly. That can
# only mean the build config is broken.
#
# Also note that a suboptimal in-between state may exist, where running
# `make -pn` reveals rules being generated with the .DEFAULT target, but
# never get executed since they're not members of the transitive closure
# of `make all`. In that case the build config could be improved.
