Decrease TurfWar background query intervals
The database is much larger than it was when we started, so these
background reporting queries have become much more expensive than
before. We also had someone make 750k claims in one day, and even
hundreds of thousands per hour, which broke our assumptions about
hourly / daily reports being cheap.

blackholed: allow changing iptables chain (#670)
* Make blackholed use its own chain

This makes blackholed interfere less with any existing iptables raw table configurations.

* Allow specifying iptables chain at runtime

blackholed will now insert blocks to the PREROUTING chain by default,
with a runtime switch to change it to another chain

Greatly expand system() shell code features
The cosmopolitan command interpreter now has 13 builtin commands,
variable support, support for ; / && / || syntax, asynchronous support,
and plenty of unit tests with bug fixes.

This change fixes a bug in posix_spawn() with null envp arg. strace
logging now uses atomic writes for scatter functions. Breaking change
renaming GetCpuCount() to _getcpucount(). TurfWar is now updated to use
the new token bucket algorithm. WIN32 affinity masks now inherit across
fork() and execve().

Improve cosmo's conformance to libc-test
This change addresses various open source compatibility issues, so that
we pass 313/411 of the tests in https://github.com/jart/libc-test where
earlier today we were passing about 30/411 of them, due to header toil.
Please note that Glibc only passes 341/411 so 313 today is pretty good!

- Make the conformance of libc/isystem/ headers nearly perfect
- Import more of the remaining math library routines from Musl
- Fix inconsistencies with type signatures of calls like umask
- Write tests for getpriority/setpriority which work great now
- conform to `struct sockaddr *` on remaining socket functions
- Import a bunch of uninteresting stdlib functions e.g. rand48
- Introduce readdir_r, scandir, pthread_kill, sigsetjmp, etc..

Follow the instructions in our `tool/scripts/cosmocc` toolchain to run
these tests yourself. You use `make CC=cosmocc` on the test repository

Rewrite IPv4 Turf War backend
It can now handle 240k SQLite write QPS at 3ms 99 percentile latency.
We're still working out the kinks since it's brand new. But we've got
this running in production already!
