Further optimize the math library The sincosf() function is now twice as fast, thanks to ARM Limited. The same might also be true of logf() and expm1f() which have been updated.

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
