Fix XNU / FreeBSD / OpenBSD / RHEL5 / NT bugs
For the first time ever, all tests in this codebase now pass, when run automatically on macos, freebsd, openbsd, rhel5, rhel7, alpine and windows via the network using the runit and runitd build tools - Fix vfork exec path etc. - Add XNU opendir() support - Add OpenBSD opendir() support - Add Linux history to syscalls.sh - Use copy_file_range on FreeBSD 13+ - Fix system calls with 7+ arguments - Fix Windows with greater than 16 FDs - Fix RUNIT.COM and RUNITD.COM flakiness - Fix OpenBSD munmap() when files are mapped - Fix long double so it's actually long on Windows - Fix OpenBSD truncate() and ftruncate() thunk typo - Let Windows fcntl() be used on socket files descriptors - Fix Windows fstat() which had an accidental printf statement - Fix RHEL5 CLOCK_MONOTONIC by not aliasing to CLOCK_MONOTONIC_RAW This is wonderful. I never could have dreamed it would be possible to get it working so well on so many platforms with tiny binaries. Fixes #31 Fixes #25 Fixes #14
