wireproto: allow wire protocol commands to declare transport support Currently, wire protocol commands are exposed on all transports. Some wire protocol commands are only supported or sensical on some transports. In the future, new wire protocol commands may only be available on new transports and legacy wire protocol commands may not be available to newer transports. This commit introduces a mechanism to allow @wireprotocommand to declare transports for which they should not be available. The mechanism for determining if a wire protocol command is available for a given transport instance has been taught to take this knowledge into account. To help implement this feature, we add a dict to wireprototypes declaring all wire transports and their metadata. There's probably room to refactor the constants used to identify the wire protocols. But that can be in another commit. Differential Revision: https://phab.mercurial-scm.org/D2483

sshpeer: don't read from stderr when that behavior is disabled We previously prevented the creation of doublepipe instances when we're not supposed to automatically read from stderr. However, there were other automatic calls to read from stderr that were undermining this effort. This commit prevents all automatic reads from stderr from occurring when they are supposed to be disabled. Because stderr is no longer being read, we need to call "readavailable" from tests so stderr is read from. Test output changes because stderr is now always (manually) read after stdout. And, since sshpeer no longer automatically tends to stderr, no "remote: " messages are printed. This should fix non-deterministic test output. FWIW, doublepipe automatically reads from stderr when reading from stdout, so I'm not sure some of these calls to self._readerr() are even needed.
