fixes: gh-1786 Added creation of PDF docs to CMake.

WIP: automation of Documentation building from cmake.

The first commmit here includes the creation of PDF's only.

Workflow:

1. Generate relative link cleaner xsl.
2. Use xsltproc to clean relative links for cmake based out of source builds.
3. Use xsltproc to process cleaned source with docbook to create FO.
4. Use apache fop to process FO into pdf.

TODO:
- Force all docs to build on a single target of `make docs`. Currently only docs that are not in a subdirectory are on this target.
- Add in cmake steps to build only docs and disable the rest of the tree. MAKE_DOCS_ONLY=ON
- Add in HTML and CHM generation.
- Add in package steps to allow for optional package creation along side the binary package.

WIP: change to handling of documentation global target to all for "make docs"

WIP: fixed version file usage.

WIP: more doc gen changes.

WIP: more changes.

WIP: doc dir moves.

WIP: doc CMake files along with xslt clean up.

WIP: finalized pdf generation from cmake.

todo:

- Doc package generation. (generate CMake files for creating package)

WIP: Fixed overflow issues with HPCCClientTools pdf.

WIP: moved wip docs to a wip directory.

wip: added MAKE_DOCS_ONLY to allow only creation of docs with only
doc deps.

Improve implicit field projection for count/exists

- Previously the output record from an activity was required to have at least one
  field, which meant that exists/count arbitrarily "used" the first field.  With
  this change that no longer happens - often reducing the number of fields used.

A record can have a _nonEmpty_ attribute associated with it to ensure
it has a non-zero size (to differenitate it from a skipped row).  The
transform clears the byte (to make memory consitant and ensure spilt
files compress properly).

Serialize/Deserialize use the default classes so they will still work.
