Summary: Some linkers (lld being one) use fallocate() or posix_fallocate() on the output file before writing its contents. EdenFS would return ENOSYS or ENOTSUP so glibc would fall back and write a single byte to every 512 byte block, which is terribly slow and generates a bunch of fake traffic in the Watchman journal. This diff implements basic support for FUSE_FALLOCATE, avoiding this slow emulation.
