bb8c315cad Storage object improvements.
* Add storageCopy(), storageMove(), and storagePathSync().

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.

f0250dab4b Move async forking and more error handling to C.
The Perl process was exiting directly when called but that interfered with proper locking for the forked async process. Now Perl returns results to the C process which handles all errors, including signals.

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.

4744eb9387 Add storagePathRemove() and use it in the Perl Posix driver.
This implementation should be faster because it does not stat each file.  It simply assumes that most directory entries are files so attempts an unlink() first.  If the entry is reported by error codes to be a directory then it attempts an rmdir().

348278bb68 Make backup directory sync more efficient.
Scanning the entire backup directory can be very expensive if there are a lot of small tables. The backup manifest contains the backup directory list so use it to perform syncs instead of scanning the backup directory.

0dce8ba2fa Make backup.history sync more efficient.
Only the backup.history/[year] directory was being synced, so check if the backup.history is newly created and sync it as well.

b234f43c9d Refactor usec to msec in common/time.c.
The implementation provides usec resolution but this is not needed in practice and it makes the interface more complicated due to the extra zeros.

2a3d6ecde8 v2.01: Minor Bug Fixes and Improvements
Bug Fixes:

* Fix --target-action and --recovery-option options being reported as invalid when restoring with --type=immediate. (Reported by Brad Nicholson.)
* Immediately error when a secure option (e.g. repo1-s3-key) is passed on the command line. Since pgBackRest would not pass secure options on to sub-processes an obscure error was thrown. The new error is much clearer and provides hints about how to fix the problem. Update command documentation to omit secure options that cannot be specified on the command-line. (Reported by Brad Nicholson.)
* Fix issue passing --no-config to embedded Perl. (Reported by Ibrahim Edib Kokdemir.)
* 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 is no reason for these processes to emit warnings. (Reported by Clinton Adams.)
* Fix manifest test in the check command when tablespaces are present. (Fixed by Cynthia Shang. Reported by Thomas Flatley.)

Improvements:

* Error when multiple arguments are set in the config file for an option that does not accept multiple arguments. (Contributed by Cynthia Shang.)
* Remove extraneous sudo commands from src/Makefile. (Contributed by Adrian Vondendriesch.)

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.

13cdb75ac5 v2.00: Performance Improvements for Archive Push
Features:

* The archive-push command is now partially coded in C which allows the PostgreSQL archive_command to run significantly faster when processing status messages from the asynchronous archive process. (Reviewed by Cynthia Shang.)

Improvements:

* Improve check command to verify that the backup manifest can be built. (Contributed by Cynthia Shang.)
* Improve performance of HTTPS client. Buffering now takes the pending bytes on the socket into account (when present) rather than relying entirely on select(). In some instances the final bytes would not be flushed until the connection was closed.
* Improve S3 delete performance. The constant S3_BATCH_MAX had been replaced with a hard-coded value of 2, probably during testing.
* Allow any non-command-line option to be reset to default on the command-line. This allows options in pgbackrest.conf to be reset to default which reduces the need to write new configuration files for specific needs.
* The C library is now required. This eliminates conditional loading and eases development of new library features.
* The pgbackrest executable is now a C binary instead of Perl. This allows certain time-critical commands (like async archive-push) to run more quickly.
* Rename db-* options to pg-* and backup-* options to repo-* to improve consistency. repo-* options are now indexed although currently only one is allowed.

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.
