7248795b91 Work on issue #48: Abandon threads and go to processes
Replaced IPC::System::Simple and Net::OpenSSH with IPC::Open3 to eliminate CPAN dependency for multiple distros.  Using open3 will also be used for local processes so it make sense to switch now.

Also stopped replacing FORMAT number which explains the large number of test log changes.  FORMAT should change very rarely and cause test log failures when it does.

148836fe44 Implemented issue #26: Info command.
* Includes updating the manifest to format 4.  It turns out the manifest and .info files were not very good for providing information.  A format update was required anyway so worked through the backlog of changes that would require a format change.

* Multiple database versions are now supported in the archive.  Does't actually work yet but the structure should be good.

* Tests use more constants now that test logs can catch name regressions.

328c2ca5c0 Much better resume:
1) Re-checksums files that have checksums in the manifest
2) Recopies files that do not have a checksum
3) Saves the manifest at regular intervals to preserve checksums
4) Unit tests for all cases (that I can think of)

a9b9ec2492 v0.61: bug fix for uncompressed remote destination
* Fixed a buffering error that could occur on large, highly-compressible files when copying to an uncompressed remote destination.  The error was detected in the decompression code and resulted in a failed backup rather than corruption so it should not affect successful backups made with previous versions.

5185d49873 v0.60: better version support and WAL improvements
* Pushing duplicate WAL now generates an error.  This worked before only if checksums were disabled.

* Database System IDs are used to make sure that all WAL in an archive matches up.  This should help prevent misconfigurations that send WAL from multiple clusters to the same archive.

* Regression tests working back to PostgreSQL 8.3.

* Improved threading model by starting threads early and terminating them late.

b37d59832f v0.50: restore and much more
* Added restore functionality.

* All options can now be set on the command-line making pg_backrest.conf optional.

* De/compression is now performed without threads and checksum/size is calculated in stream.  That means file checksums are no longer optional.

* Added option `--no-start-stop` to allow backups when Postgres is shut down.  If `postmaster.pid` is present then `--force` is required to make the backup run (though if Postgres is running an inconsistent backup will likely be created).  This option was added primarily for the purpose of unit testing, but there may be applications in the real world as well.

* Fixed broken checksums and now they work with normal and resumed backups.  Finally realized that checksums and checksum deltas should be functionally separated and this simplied a number of things.  Issue #28 has been created for checksum deltas.

* Fixed an issue where a backup could be resumed from an aborted backup that didn't have the same type and prior backup.

* Removed dependency on Moose.  It wasn't being used extensively and makes for longer startup times.

* Checksum for backup.manifest to detect corrupted/modified manifest.

* Link `latest` always points to the last backup.  This has been added for convenience and to make restores simpler.

* More comprehensive unit tests in all areas.

4bc4d97f2b v0.30: core restructuring and unit tests
* Complete rewrite of BackRest::File module to use a custom protocol for remote operations and Perl native GZIP and SHA operations.  Compression is performed in threads rather than forked processes.

* Fairly comprehensive unit tests for all the basic operations.  More work to be done here for sure, but then there is always more work to be done on unit tests.

* Removed dependency on Storable and replaced with a custom ini file implementation.

* Added much needed documentation (see INSTALL.md).

* Numerous other changes that can only be identified with a diff.

587bd1f8d9 v0.10: Backup and archiving are functional
This version has been put into production at Resonate, so it does work, but there are a number of major caveats.

* No restore functionality, but the backup directories are consistent Postgres data directories.  You'll need to either uncompress the files or turn off compression in the backup.  Uncompressed backups on a ZFS (or similar) filesystem are a good option because backups can be restored locally via a snapshot to create logical backups or do spot data recovery.

* Archiving is single-threaded.  This has not posed an issue on our multi-terabyte databases with heavy write volume.  Recommend a large WAL volume or to use the async option with a large volume nearby.

* Backups are multi-threaded, but the Net::OpenSSH library does not appear to be 100% threadsafe so it will very occasionally lock up on a thread.  There is an overall process timeout that resolves this issue by killing the process.  Yes, very ugly.

* Checksums are lost on any resumed backup. Only the final backup will record checksum on multiple resumes.  Checksums from previous backups are correctly recorded and a full backup will reset everything.

* The backup.manifest is being written as Storable because Config::IniFile does not seem to handle large files well.  Would definitely like to save these as human-readable text.

* Absolutely no documentation (outside the code).  Well, excepting these release notes.

* Lots of other little things and not so little things.  Much refactoring to follow.
