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
