Building the target `apply-coding-conventions` runs clang-format on any
source file in the project.

minor reorganization of qmt test runner arguments

Reorganized command line arguments of test runner for .qmt files to
simplify finding relevant informations in a call to `ctest -V`,
e.g. to run a test by hand.

If the insteance does not have a MsgStream associated, at the first call to
CommonMessaging::msgLevel(), the MsgStream is created to ensure that m_level
is initialized to the most appropriate value.

If the OutputLevel option is not explicitly set, the msgLevel must be
inherited from that of the created MsgStream (which takes it from the
MessageSvc settings).

* protect PATH from local directories
* restore `outputLevel()` method removed with mr !76 (b0618f78)

Fixes GAUDI-1181

This change was necessary after a recent update in the ATLAS build
setup, that pulled in some externals from local directories. Where
adding /usr/bin to PATH broke the execution of the dictionary
generators.

Comparing standard output to reference files, a regular expression is
used to find histogram summaries, but it was failing when color output
was enabled.

- add `LCG_platform` to `manifest.xml` (fixes LBCORE-1048)
- allow empty environment variable `HEPTOOLS_VERSION`

See merge request !108

Treat empty HEPTOOLS_VERSION (override version specified in
toolchain.cmake) as not set, instead of requiring that it is really not
set.

This test confuses interpolation and extrapolation. These have
historically been the same in GSL, but haven't been for a while now. If
you want to extrapolate, you have to tell GSL to do so explicitly.

The test is modified to solely do interpolation.

Relevant GSL commit from 2010 which makes extrapolation using interpolation routines an error : http://bzr.savannah.gnu.org/lh/gsl/trunk/revision/4704 .

GaudiCommon adds a property GlobalTimeOffset and a corresponding getter
globalTimeOffset to every algorithm/tool which uses GaudiCommon,
regardless on whether this property is used.

As there is no code anymore that actually uses globalTimeOffset, this
patch removes this accessor and the corresponding property.

Fixes GAUDI-1122.

The version of ToolHandle.h before fa29ed33 included some improvements,
as well as the fixes for https://sft.its.cern.ch/jira/browse/CFHEP-177 and GAUDI-1127.

The version introduced with fa29ed33 does not work because of GAUDI-1127.
