The archive_status directory is now recreated on restore to support PostgreSQL 8.3 which does not recreate it automatically like more recent versions do.
Also fixed log checking after PostgreSQL shuts down to include FATAL messages and disallow immediate shutdowns which can throw FATAL errors in the log.
Reported by Stephen Frost.
Modified the info command (both text and JSON output) to display the archive ID and minimum/maximum WAL currently present in the archive for the current and prior, if any, database cluster version.

The integration tests that were supposed to prevent this regression did not work as intended. They verified the contents of a table in the (supposedly) restored tablespace, deleted the table, and then deleted the tablespace. All of this was deemed sufficient to prove that the tablespace had been restored correctly and was valid.
However, PostgreSQL will happily recreate a tablespace on the basis of a single full-page write, at least in the affected versions. Since writes to the test table were replayed from WAL with each recovery, all the tests passed even though the tablespace was missing after the restore.
The tests have been updated to include direct comparisons against the file system and a new table that is not replayed after a restore because it is created before the backup and never modified again.
Versions ≥ 9.0 were not affected due to numerous synthetic integration tests that verify backups and restores file by file.
* More optimized container suite that greatly improves build time.
* Added static Debian packages for Devel::Cover to reduce build time.
* Add deprecated state for containers. Deprecated containers may only be used to build packages.
* Remove Debian 8 from CI because it does not provide additional coverage over Ubuntu 14.04 and Ubuntu 16.04.
The options accommodate systems where CAs are not automatically found by IO::Socket::SSL, i.e. RHEL7, or to load custom CAs.
Suggested by Scott Frazer.
* Combine hardlink and non/compressed in synthetic tests to reduce test time and improve coverage.
* Change log level of hardlink logging to detail.
* Cast size in S3 manifest to integer.
