PR: 190954
Submitted by: Joe Benden
The stage PR worked, but there were existing problems that weren't fixed,
such as muted install commands, "cp -r" instead of install macros, the use
of "-" prefix on commands that won't fail. A list of additional, "while
we are here changes":
* 16,000+ line, 1.1Mb pkg-plist removed, autogen instead
* Remove now-unnecessary x-generate-plist maintainer target
* Remove PLIST_SUB lines
* Remove unnecessary roll-your-own extract target. Leave one original
deletion as a post-extract target
* Use COPYTREE_SHARE instead of "cp -r"
* move CHOWN operations to pkg-plist generation
