Remove legacy and cmake compile systems

- Remove legacy and cmake compile systems from makefiles and config
- Clean out various dead code from makefile and lib/petsc/conf/rules
- Update lib/petsc/conf/test to build all examples, not just those beginning with ex, update examples makefiles to remove now unneeded rules
- Deprecated make gnumake, replaced with make libs

Note: retained clean-legacy since it is used by clean in rules

Man pages: remove .keywords: fields

This field is recognized by doctext from Sowing (http://wgropp.cs.illinois.edu/projects/software/sowing/doctext/node20.htm#Node20),
but it doesn't seem to be uniformly used or maintained.

Thus, remove all .keywords: fields, and a following blank line, if present.

This is accomplished with GNU sed (gsed on OS X), with the following commands.
*Warning* that this type of command can corrupt a .git directory,
so be cautious in reusing or modifying these commands. They first look
for and delete matching lines with a following line consisting of only whitespace,
and then delete any remaining matching lines.

find src/ -type f -exec gsed -i '/keywords:/ {N; /\n\s*$/d}' {} +
find src/ -type f -exec gsed -i '/keywords:/d' {} +
find include/ -type f -exec gsed -i '/keywords:/ {N; /\n\s*$/d}' {} +
find include/ -type f -exec gsed -i '/keywords:/d' {} +

Hints on the sed command obtained from: https://unix.stackexchange.com/questions/100754/how-to-delete-a-specific-line-and-the-following-blank-line-using-gnu-sed

Plex: Implemented pullback/pushforward

Approved-by: BarryFSmith <bsmith@mcs.anl.gov>

PetscFE: Removed unused variables

PetscFE: Reduce debugging overhead
- Hopefully this eliminates the performance penalty of the
reorganization

Plex: Complex fixes
- The geometry is never complex
- The fields are always complex

Doc+Dualspace: More seealsos

Dualspace: Support 1D derivative transformation

Plex: Implemented pullback/pushforward - Added k to PetscDualSpace. It indicates what kind of transformation we use. - DualSpace does pullback and FE integration routines do pushforward - All integration now takes a PetscFEGeom argument and pushes forward correctly - Added PetscDualSpaceTransformType - Removed TransformF() because we now transform the basis function instead - Chaged workspace management in DS - Updated L2 diff functions - Updated interpolation functions - Added way to output exact solution in DMSNESCheck()
