wmakeFindEmptyMake:
- Find 'Make/' directories without 'files' or 'options'.
  These typically correspond to (partially) removed applications.

BUG: syntax error in settings.sh

- main mplib rules located in GENERAL_RULES with specializations
  (if any) under RULES. Modest change in a few options files, but
  cleans up the rules directories.

  previously in options:
      include $(RULES)/mplib$(WM_MPLIB)

  now in options:
      sinclude $(GENERAL_RULES)/mplib$(WM_MPLIB)
      sinclude $(RULES)/mplib$(WM_MPLIB)

  For GNU make it would be permissible to write both in a single line.

ATTENTION: cpp now needs '-traditional-cpp' for single-line output

- adds more DWIM (do what I mean) intelligence to wmake

ENH: use ~/.OpenFOAM/.wmake instead of ~/.wmakeScheduler for the lock dir

- keeps more of the OpenFOAM bits together

- otherwise /lib/cpp may need a different library binding than
  currently available and results in this type of error:

  /usr/lib64/gcc/x86_64-suse-linux/4.4/cc1:
  /data/app/OpenFOAM/ThirdParty-1.6.x/platforms/linux64/gcc-4.3.3/lib64/libstdc++.so.6:
  version `GLIBCXX_3.4.11' not found (required by
  /usr/lib64/libppl_c.so.2)

ENH: remove unused flex++ rule for SiCortex that was identical to the
general one anyhow.

ENH: generalize rule for X11

ENH: Avoid move in flex/flex++ rule.

- more consistent script names
- remove '-help' option from internal scripts

COMP: latest coco-cpp can find the frame files relative to the
executable path. This simplifies the make rules.

present.

- specifies headers that should be ignored. Provides a workaround
  for the fact that wmkdep/wmkdepend doesn't handle defines at all.

STYLE: code cleanup of wmkdep.l

old: $WM_THIRD_PARTY_DIR/<packageName>/platforms/$WM_ARCH*
new: $WM_THIRD_PARTY_DIR/platforms/$WM_ARCH*/<packageName>

This streamlines the creation of binary packs, eases distribution and
helps when testing the robustness of relocatable installations.

This signals that we are using the system installed openmpi version.

- This avoids dependency on lex/flex and provides better encapsulation
  for buffer switching. As a result, the maximum number of open files
  only corresponds to the include depth.

- handles basic operations, references to other dictionary entries
  (with '$name' syntax) and assorted mathematical functions:

      pi(), degToRad, radToDeg, asin, acos, atan, sin, cos, tan, log,
      log10, mag, atan2, pow

The basic syntax: #calc{ ... };

NOTE the trailing ';' is required for the primitiveEntry to be
properly defined.

Include character class (wchar_t or char) as a template parameter in
CocoParserErrors.

This reverts commit 5050e9e6.

Adding -lrt to decompositionMethods/decompositionMethods/Make/options
to get rid of get_clocktime error.
