At one time there was a lot more in this header but it got merged with the enums and constants in config.auto.c, leaving only the ConfigOptionType enum.
Auto-generating the ConfigOptionType enum is not very useful since new option types require code in parse.c.

HRN_CFG_LOAD() handles the majority of test configuration loads and has various options for special cases.
It was not clear when to use harnessCfgLoadRaw() vs harnessCfgLoad(). Now "raw" functionality is granular and enabled by parameters, e.g. noStd.
Make the macros more consistent in format and make sure that each macro outputs a line number before doing any work so when errors happen it is clear where they happened.
Add noRecurse option to TEST_STORAGE_LIST().
Add comment option to all storage macros.
Instead store the line number in hrnTestLogPrefix() so it doesn't need to be passed to hrnTestResultBegin().
Also add missing linefeed in hrnStorageList().
All instances of storageTest are better represented with storagePg*(), which allows TEST_PATH and TEST_PATH_PG to be omitted.
Also remove some headers which are no longer needed.
The default is to keep all backup history to match the current behavior. In minimal configuration (0 days), unexpired backups are always kept in history.
When a full backup manifest expires, all dependent differential/incremental manifests expire as well.
Run the remote process inside a forked child process instead of exec'ing it. This allows coverage to accumulate in the remote process rather than needing to test the remote protocol functions directly, resulting in better end-to-end testing and less test duplication. Another advantage is that the pgbackrest binary does not need to be built for the test and the test does not need to run in a container.
This allows protocolRemoteExec() to be shimmed, which means the remote can be run as a child of the test process, simplifying coverage testing.
The shim does not need SSH parameters, so also split those out into a separate function and update the tests to match.
Add executable to parameter list to avoid first option being lost. The backup, restore, and verify tests worked OK with their first option being defaulted because it ended up being job-retry which worked fine as the default.
Add hrnProtocolLocalShimUninstall() allow the shim to be uninstalled.
Log shim at debug level to make it obvious in the logs when a shim is in use.
There are no code changes from PostgreSQL 13 so simply add the new version.
Add CATALOG_VERSION_NO_MAX to allow the catalog version to "float" during the PostgreSQL beta/rc period so new pgBackRest versions are not required when the catalog version changes.
Update the integration tests to handle new PostgreSQL startup messages.
manifestLinkCheck() was pretty inefficient so large numbers of links caused it to use a lot of memory and eventually crash. This is a more efficient implementation which runs O(nlogn) and uses far less memory.
Checking for duplicate file links has been added, which represents a change in behavior, but hopefully a good one.
The user guide was split primarily to provide documentation for the stop-auto option in PostgreSQL <= 9.5. Now that 9.5 is EOL there does not seem to be a good reason to generate an extra user guide. The stop-auto function is still documented in the reference.
Leave the stop-auto documentation in the user guide in case we want to manually generate documentation for older versions.
Also rename centos to rhel for most identifiers since that is the core platform we are building for, similar to how we label 'debian' builds even though we generally use Ubuntu. With CentOS set to become an upstream for RHEL later this year, we'll likely need to pick a new test distribution, perhaps Rocky Linux if that gets off the ground.
Test and remove WAL segment 000000010000000100000002 in the test where it is created rather than as a byproduct of a much later test.
Remove incorrect local role from test. It worked, but was not the correct command role to be using when calling cmdArchiveGet().
Move some harness headers down to the correct section.
Comment formatting was not used much but it incurred a heavy cost in each macro to process possible formatting.
Remove formatted comments where they did not contain valuable information and replace with strZ(strNewFmt()) otherwise.
A define was already added for TEST_PATH but it was not widely used. Replace all occurrences of testPath() with TEST_PATH in the tests.
Replace testUser() with TEST_USER, testGroup() with TEST_GROUP, testRepoPath() with HRN_PATH_REPO, testDataPath() with HRN_PATH, testProjectExe() with TEST_PROJECT_EXE, and testScale() with TEST_SCALE.
Replace {[path]}, {[user]}, {[group]}, etc. with defines and remove hrnReplaceKey(). This is better than having two ways to deal with replacements.
In some cases the original test*() getters were kept because they are used by the harness, which does not have access to the new defines. Move them to harnessTest.intern.h to indicate that the tests should no longer use them.
Replace all instances of strNew("") with strNew() and use strNewZ() for non-empty zero-terminated strings. Besides saving a useless parameter, this will allow smarter memory allocation in a future commit by signaling intent, in general, to append or not.
In the tests use STRDEF() or VARSTRDEF() where more appropriate rather than blindly replacing with strNewZ(). Also replace strLstAdd() with strLstAddZ() where appropriate for the same reason.
Run the local process inside a forked child process instead of exec'ing it. This allows coverage to accumulate in the local process rather than needing to test the local protocol functions directly, resulting in better end-to-end testing and less test duplication. Another advantage is that the pgbackrest binary does not need to be built for the test.
The backup, restore, and verify command tests have been updated to use the new shim for coverage.
A shim allows a test harness to access static functions and variables in a C module, and also allows functions to be shimmed (i.e. overridden) for the purposes of testing.
For instance, coverage testing works when a process that is normally exec'd is run as a forked child process instead.
getopt_long() requires an exhaustive list of all possible options that may be found on the command line. Because of the way options are indexed (e.g. repo1-4, pg1-8) optionList[] has 827 entries and we have kept it small by curtailing the maximum indexes very severely. Another issue is that getopt_long() scans the array sequentially so parsing gets slower as the index maximums increase.
Replace getopt_long() with a custom implementation that behaves the same but allows options to be parsed with a function instead of using optionList[]. This commit leaves the list in place in order to focus on the getopt_long() replacement, but cfgParseOption() could be replaced with a more efficient implementation that removes the need for optionList[].
This implementation also fixes an issue where invalid options were misreported in the error message if they only had one dash, e.g. -config. This seems to have been some kind of problem in getopt_long(), but no investigation was done since the new implementation fixes it.
Tests were added at 0825428, 2b8d2da, 34dd663, and 384f247 to check that previously untested getopt_long() behavior doesn't change.
This makes the macro useful when subpaths are present.
Identify types other than files (path, link, etc.) with a single appended character for easier debugging.
