Fix Gitlab issue #1423

- foamExec was removed as part of commit 6c68c34e but
  overlooked the fact that it is partly still needed by foamJob.
  When running in parallel, it is used to source the etc/bashrc env.

  Reinstated a stripped down form, which has been relocated to
  bin/tools directory (it should not be directly called by the user).

  The previous version switching functionality has nonetheless be
  dropped since it only worked only when a rigid naming convention for
  OpenFOAM installations was followed.

ENH: add foamJob log=, -log-app, -no-log options, improved coding quality

edge it sets the globalEdgeOrientation

See #1367

- synchronization, reduction only makes sense on processor-coupled
  patches. Since cyclic baffles are within a single processor domain,
  they are not reduced. So need to skip the sanity test for these.

- the use of 'paraview --version' can be fail if the build host
  doesn't have the necessary graphics. For this case, try to obtain
  the ParaView API number from the associated include directory.

- the read offset missed the tag_ member entirely and thus the entire
  particle information would be corrupt (incorrectly interpreted) as
  well as potential violation of adjacent (trailing) memory locations.

- use git show --ignore-space-change when examining

- need to be more generous when prefiltering the cell selection

- now catch these and emit a warning.
  Still need to investigate the root cause in the caller(s) or regionSplit.

- the behaviour of std::rename with overwriting an existing file is
  implementation dependent:
    - POSIX: it overwrites.
    - Windows: it does not overwrite.

- for Windows need to use the ::MoveFileEx() routine for overwriting.

  More investigation is needed for proper handling of very long names.

- this cannot be left as a configurable value (on windows), since it
  needs to be enabled even prior to reading the etc/controlDict file,
  in case the OpenFOAM installation path itself contains spaces.

- reduced clutter. Mostly only need to scan source tree.

- 00-dummy: use wmake/src/Allmake to get native (not cross-compiled)
  wmake toolchain binaries
