Bug Fixes:
* Fixed missing variable replacements.
* Removed hard-coded host names from configuration file paths.
Documentation Features:
* Allow command-line length to be configured using cmd-line-len param.
* Added compact param to allow CSS to be embedded in HTML file.
* Added pretty param to produce HTML with proper indenting.
* Only generate HTML menu when required and don't require index page.
* Assign numbers to sections by default.
* VM mount points are now optional.
This meant that the queue would never be cleared without manual intervention (such as calling archive-push directly). PostgreSQL now receives errors when there is not enough space to store new WAL segments but the async process will still be started so that space is eventually freed.
Reported by Jens Wilke.
Controls whether console log messages are sent to stderr or stdout. By default this is set to warn which represents a change in behavior from previous versions, even though it may be more intuitive. Setting log-level-stderr=off will preserve the old behavior.
Suggested by Sascha Biberhofer.
* Fixed error message to properly display the archive command when an invalid archive command is detected.
* Check that archive_mode is enabled when archive-check option enabled.
* pgBackRest version number included in command start INFO log output.
* Process ID logged for local process start/stop INFO log output.
* Fixed missing expect output for help module.
* Fixed an issue where local processes were not disconnecting when complete and could later timeout. (Reported by Todd Vernick.)
* Fixed an issue where the protocol layer could timeout while waiting for WAL segments to arrive in the archive. (Reported by Todd Vernick.)
* Fixed an issue where retention-archive was not automatically being set when retention-archive-type=diff, resulting in a less aggressive than intended expiration of archive.
* Additional warnings when archive retention settings may not have the intended effect or would allow indefinite retention.
* Closed#235: "Retention policy question" by adding documentation for archive retention.

A connection to the primary cluster is still required to start/stop the backup and copy files that are not replicated, but the vast majority of files are copied from the standby in order to reduce load on the master.
Master and standby can both be configured on the backup server and pgBackRest will automatically determine which is the master. This means no configuration changes for backup are required after failing over from a master to standby when a separate backup server is used.
These include (depending on the version where they were introduced): pgsql_tmp, pg_dynshmem, pg_notify, pg_replslot, pg_serial, pg_snapshots, pg_stat_tmp, pg_subtrans. The postgresql.auto.conf.tmp file is now excluded in addition to files that were already excluded: backup_label.old, postmaster.opts, postmaster.pid, recovery.conf, recovery.done.
* Tablespace paths that had $PGDATA as a substring would be identified as a subdirectories of $PGDATA even when they were not.
* Also hardened relative path checking a bit.
This is a better approach than 93320b8 (reverted in this commit) because it ensures that the remote type will be none so any functions that utilize optionRemoteTypeTest will work correctly.
This bug was only an issue when backup-host was not properly configured on the database host.
