Fix bugs and make improvements
- Get clone() working on FreeBSD - Increase some Python build quotas - Add more atomic builtins to chibicc - Fix ASAN poisoning of alloca() memory - Make MODE= mandatory link path tinier - Improve the examples folder a little bit - Start working on some more resource limits - Make the linenoise auto-complete UI as good as GNU readline - Update compile.com, avoiding AVX codegen on non-AVX systems - Make sure empty path to syscalls like opendir raises ENOENT - Correctly polyfill ENOENT vs. ENOTDIR on the New Technology - Port bestline's paredit features to //third_party/linenoise - Remove workarounds for RHEL 5.0 bugs that were fixed in 5.1
