Redesign cosmocc toolchain
The `cosmocc` compiler is now being distributed as a self-contained
toolchain that's path-agnostic and it no longer requires you clone the
Cosmop repo to use it. The bin/ folder has been deleted from the mono
repo. The `fatcosmocc` command has been renamed to `cosmocc`. MacOS
support now works very well.

Improve mkdeps
Our makefile generator now accepts badly formatted include lines. It's
now more hermetic with better error checking in the cosmo repo, and it
can be configured to not be hermetic at all.

Fix apelink shell script corruption bug
We were using a shell heredoc value '@' to terminate the dos stub, but
that's not sufficiently safe. We found out sh doesn't consider control
characters as contributing to the start of a line, and had the unlucky
chance of the linker choosing the number 2624 for e_lfanew, and that's
"@\n" in ASCII, which compromised the APE shell script.

We now use the heredoc 'justineXXXXXX' with 31 bits of entropy, that's
determistically generated by hashing apelink inputs w/ crc32 / blake2b

Make fatcosmocc good enough to build Lua 5.4.6
make all test CC=fatcosmocc AR='fatcosmoar rcu'

This change introduces a program named mktemper.com which provides more
reliable and secure temporary file name generation for scripts. It also
makes our ar.com program more permissive in what commands it'll accept.
The cosmocc command is improved by this change too.

Introduce new fatcosmocc command
This new script is an alternative to the `cosmocc` command. It's still a
work in progress. It abstracts all the gory details of building separate
copies of your executable and then running the apelink.com program.
