net: let OS-specific AddFD routine wake up polling thread.

2011-03-28T19:39:09Z

With gccgo some operating systems require using select rather than epoll or kevent. Using select means that we have to wake up the polling thread each time we add a new file descriptor. This implements that in the generic code rather than adding another wakeup channel, even though nothing in the current net package uses the capability.

go/ast: implemented NewPackage

2011-03-28T17:46:26Z

NewPackage creates an ast.Package node from a set of package files and resolves unresolved identifiers. Also: - Changed semantics of Scope.Insert: If an object is inserted w/o errors, the result is nil (before it was obj). - Fixed an identifier resolution bug in the parser: map keys must not be resolved. gotype runs through several go/* packages and successfully resolves all (non-field/method) identifiers.

runtime: fix gdb support for goroutines.

2011-03-28T15:34:22Z

in gdb, 'info goroutines' and 'goroutine were crashing because the 'g' and 'm' structures had changed a bit. R=rsc CC=golang-dev https://golang.org/cl/4289077
