880fbb5e57 Add checksum delta for incremental backups.
Use checksums rather than timestamps to determine if files have changed.  This is useful in cases where the timestamps may not be trustworthy, e.g. when performing an incremental after failing over to a standby.

If checksum delta is enabled then checksums will be used for verification of resumed backups, even if they are full.  Resumes have always used checksums to verify the files in the repository, enabling delta performs checksums on the database files as well.

Note that the user must manually enable this feature in cases were it would be useful or just keep in enabled all the time.  A future commit will address automatically enabling the feature in cases where it seems likely to be useful.

bf0691576a Allow delta option to be specified in the pgBackRest configuration file.
This option was previously allowed on the command-line only for no particular reason that we could determine.

Being able to specify it in the config file seems like a good idea and won't change current usage.

d41570c37a Improve log file names for remote processes started by locals.
The log-subprocess feature added in 22765670 failed to take into account the naming for remote processes spawned by local processes.  Not only was the local command used for the naming of log files but the process id was not pass through.  This meant every remote log was named "[stanza]-local-remote-000" which is confusing and meant multiple processes were writing to the same log.

Instead, pass the real command and process id to the remote.  This required a minor change in locking to ignore locks if process id is greater than 0 since remotes started by locals never lock.

bef58a7974 Allow arbitrary directories and/or files to be excluded from a backup.
Misuse of this feature can lead to inconsistent backups so read the --exclude documentation carefully before using.

3434240097 Remove incompletely implemented online option from the check command.
Offline operation runs counter to the purpose of this command, which is to check if archiving and backups are working correctly.

6a40c916d4 Add repo-s3-token option to allow temporary credentials tokens to be configured.
pgBackRest currently has no way to request new credentials so the entire command (e.g. backup, restore) must complete before the credentials expire.

54dd6f3ed4 Add asynchronous, parallel archive-get.
This feature maintains a queue of WAL segments to help reduce latency when PostgreSQL requests a WAL segment with restore_command.

27aa5f756e Add support for additional pgBackRest configuration files.
Configuration files are loaded from the directory specified by the --config-include-path option.

Add --config-path option for overriding the default base path of the --config and --config-include-path option.

79b7552940 Rename archive-queue-max option to archive-push-queue-max.
This avoids confusion with the archive-get-queue-max option. The old option name will continue to be accepted.

6fd0c3dcaa Improved lock implementation written in C.
Now only two types of locks can be taken: archive and backup. Most commands use one or the other but the stanza-* commands acquire both locks. This provides better protection than the old command-based locking scheme.

2c1687721e Fix issue where specifying log-level-stderr > warn would cause a local/remote process to error on exit due to output found on stderr when none was expected.
The max value for a local/remote process is now error since there's no reason for these processes to emit warnings.

03f1082e86 Improve logging.
Move command begin to C except when it must be called after another command in Perl (e.g. expire after backup). Command begin logs correctly for complex data types like hash and list. Specify which commands will log to file immediately and set the default log level for log messages that are common to all commands. File logging is initiated from C.

72cbb9a9d4 Call Perl with built-in interpreter instead of execvp().
Exec'ing Perl worked fine but generated a very large command line in the process list and potentially exposed secrets.

99a0721631 Allow any non-boolean, non-command-line option to be negated.
This allows specific options in pgbackrest.conf to be ignored (and set to default) which reduces the need to write new configuration files for specific needs.

Note that boolean, non-command-line options are already negatable.

c5fc88d340 Fixed an issue that suppressed locality errors for backup and restore.
When a backup host is present, backups should only be allowed on the backup host and restores should only be allowed on the database host unless an alternate configuration is created that ignores the remote host.
