The vast majority of Strings are never modified so for most cases allocate memory for the string with the object. This results in one allocation in most cases instead of two. Use strNew() if strCat*() functions are needed.
Update varNewStr() in the same way since String Variants can never be modified. This results in one allocation in all cases instead of three. Also update varNewStrZ() to use STR() instead of strNewZ() to save two more allocations.
Rather than working directly with Buffer types, define a new Pack pseudo-type that represents a Buffer containing a pack. This makes it clearer that a pack is being stored and allows stronger typing.
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.
