Report progress of streaming base backup.

Browse Source 
This commit adds pg_stat_progress_basebackup view that reports
the progress while an application like pg_basebackup is taking
a base backup. This uses the progress reporting infrastructure
added by c16dc1aca5e0, adding support for streaming base backup.

Bump catversion.
