platform: implement readpipe() Reading all available data from a pipe has a platform-dependent implementation. This patch establishes platform.readpipe() by copying the inline implementation in sshpeer.readerr(). The implementations for POSIX and Windows are currently identical. The POSIX implementation will be changed in a subsequent patch.
