- the various information queries MUST be executed with
  the '--no-print-directory' or risk polluting values
  in the information queries.

  This is mostly seen with the 'canCompile' test for tutorials running
  in parallel.

- backported fix from develop

COMP: incorrect variable names in PtrListOpsTemplates.C

- regression from f721b534

- use long form to avoid dash 0.5.8 error (ubuntu bionic)

- consolidate the prefix handling into modules/Allwmake

- When OpenFOAM is under git control and a 'debian/' directory exists,
  this could mean two things:

  1) Additional debian control has been added to OpenFOAM
  2) OpenFOAM has been imported into a debian project

For the case that OpenFOAM has been imported into a debian project,
using the git information would be highly misleading. There will be no
OpenFOAM SHA1 correspondence.

However, if additional debian control has been added to OpenFOAM the
SHA1 will be valid.

The ad hoc solution is to use an additional "openfoam.debian"
directory to flag the addition of debian controls into openfoam.

When a "debian/" directory exists without a "openfoam.debian", assume
that the OpenFOAM has been imported into debian and do not use the SHA1.

- fix older '> >' template parameters as '>>'

- used fluidThermo::typeName instead of fluidThermo::dictName
  within the Cp() method.

- only checked if it started with '/' and not 'd:/' (for example).

- affects ensightSurfaceReader only.

  If there are no `*` characters, protect against replacement.
  Otherwise it would attempt to replace a zero-length string with
  a single `0`, which results in prepending the name.

STYLE: ensightSurfaceReader constructor explicit
