v2.40: OpenSSL 3 Support

NOTE TO PACKAGERS: An experimental meson build has been added but packagers should continue to use the autoconf/make build for the foreseeable future.

Improvements:

* OpenSSL 3 support. (Reviewed by Stephen Frost.)
* Create snapshot when listing contents of a path. (Reviewed by John Morris, Stephen Frost.)
* Force target-timeline=current when restore type=immediate. (Reviewed by Stephen Frost.)
* Truncate files during delta restore when they are larger than expected. (Reviewed by Stephen Frost.)
* Disable incremental manifest save when resume=n. (Contributed by Reid Thompson. Reviewed by David Steele.)
* Set backup percent complete to zero before copy start. (Contributed by Reid Thompson. Reviewed by David Steele.)
* Use S3 IsTruncated flag to determine list continuation. (Reviewed by John Morris, Soulou. Suggested by Christian Montagne.)

Documentation Bug Fixes:

* Skip internal options in the configuration reference. (Reported by Francisco Miguel Biete.)

Documentation Improvements:

* Add link to PostgreSQL configuration in repository host section. (Reviewed by Stefan Fercot. Suggested by Julien Cigar.)

Test Suite Improvements:

* Add experimental Meson build. (Reviewed by Eli Schwartz, Sam Bassaly.)
* Allow any path to be passed to the --test-path option. (Contributed by Andrey Sokolov. Reviewed by David Steele.)
* Fix compile error when DEBUG_EXEC_TIME is defined without DEBUG. (Contributed by Andrey Sokolov. Reviewed by David Steele.)
