This patch copies the channel implementation from the master Go library to the gccgo library. This is a followon patch to the earlier change to multiplex goroutines onto threads. With this patch channels now use the goroutine scheduler directly, rather than taking up a thread by using a condition variable. This required changing the runtime calls that the compiler generates for select statements. Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu. Committed to mainline.
