TCPRewriter: add perform_mapping handler
Avoid unused variable warning
click-buildtool internals: Print #include directives in a stable order.

caused problems at Meraki for Jim Roewe and Cliff Frey.
Internal: Use a helper function to parse elementmaps for a package.
Improve click-mkmindriver performance with packages.

* Actually add package elements to the list of requirements.
* Use package() to determine which package an element is in, not
  some jankass crap.
* Also, -V reports which elementmaps were parsed.

Von Cliff complainert.
Click-elem2man: Install element manual pages in section 7.

Apparently section n is discouraged by Linux standards. Error
from lintian, reported by Francesco Berni. Also install man
pages gzipped.
More elementdoc nits.

StrideSwitch.
