Taru Karttunen f5f480e1df os: reduce allocations in Readdir on unix 
Include syscall.Stat_t on unix to the
unexported fileStat structure rather than
accessing it though an interface.

Additionally add a benchmark for Readdir
(and Readdirnames).

Tested on linux, freebsd, netbsd, openbsd
darwin, solaris, does not touch windows
stuff. Does not change the API, as
discussed on golang-dev.

E.g. on linux/amd64 with a directory of 65 files:

benchmark              old ns/op     new ns/op     delta
BenchmarkReaddir-4     67774         66225         -2.29%

benchmark              old allocs     new allocs     delta
BenchmarkReaddir-4     334            269            -19.46%

benchmark              old bytes     new bytes     delta
BenchmarkReaddir-4     25208         24168         -4.13%

The Go Programming Language

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.

Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.

Go is the work of hundreds of contributors. We appreciate your help!

To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html

Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
