Merge branch 'master' into experimental
Adding special C code that allows redis's async client to use goroutines
and poll (on Linux) to check the status of file descriptors. These
goroutines replace the functionality of other C libraries like libevent.

These changes fixes some problems of client disconnection within a
SUBSCRIBE or PSUBSCRIBE context.

Commited changes are still experimental.
Stealing more great stuff from src/pkg/net/fd_* to watch file descriptors.
