Use a lexer and grammar for parsing walsender commands Makes it easier to parse mainly the BASE_BACKUP command with it's options, and avoids having to manually deal with quoted identifiers in the label (previously broken), and makes it easier to add new commands and options in the future. In passing, refactor the case statement in the walsender to put each command in it's own function.

Add pg_basebackup tool for streaming base backups This tool makes it possible to do the pg_start_backup/ copy files/pg_stop_backup step in a single command. There are still some steps to be done before this is a complete backup solution, such as the ability to stream the required WAL logs, but it's still usable, and could do with some buildfarm coverage. In passing, make the checkpoint request optionally fast instead of hardcoding it. Magnus Hagander, reviewed by Fujii Masao and Dimitri Fontaine
