This was intended to separate the code changes from documentation and test suite changes but it arguably does not add any clarity.
Since documentation and test suite changes are explicitly marked as such that should be clear enough.
IMPORTANT NOTE: The log-level-stderr option default has been changed from warn to off. This makes it easier to capture errors when only redirecting stdout. To preserve the prior behavior set log-level-stderr=warn.
NOTE TO PACKAGERS: The lz4 library is now required by the meson build.
NOTE TO PACKAGERS: Compiler support for __builtin_clzl() and __builtin_bswap64() is now required by the meson build.

Double spaces have fallen out of favor in recent years because they no longer contribute to readability.
We have been using single spaces and editing related paragraphs for some time, but now it seems best to update the remaining instances to avoid churn in unrelated commits and to make it clearer what spacing contributors should use.
Command-line help is now generated at build time so it does not need to be committed. This reduces churn on commits that add configuration and/or update the help.
Since churn is no longer an issue, help.auto.c is bzip2 compressed to save space in the binary.
The Perl config parser (Data.pm) has been moved to doc/lib since the Perl build path is no longer required.
Likewise doc/xml/reference.xml has been moved to src/build/help/help.xml since it is required at build time.
Linefeeds were originally used in the place of <p> tags to denote a paragraph. While much of the linefeed usage has been replaced over time, there were many places where it was still being used, especially in reference.xml. This made it difficult to get consistent formatting across different output types. In particular there were formatting issues in the command-line help because it is harder to audit than HTML or PDF.
Replace linefeed formatting with proper <p> tags to make formatting more consistent.
Remove double spaces in all text where <p> tags were added since it does not add churn.
Update all <ul>/<ol>/<li> tags to the more general <list>/<list-item> tags.
Add a few missing periods.
The primary source for project info is now src/version.h.
The pgBackRestDoc::ProjectInfo module loads the project info from src/version.h at runtime so there is no need to update it.
This is consistent with the way BackRest and BackRest test were renamed way back in 18fd2523.
More modules will be moving to pgBackRestDoc soon so renaming now reduces churn later.
