Description of changes:

  • remove the silent conversion of the incorrect input parameter dimension=[0,0,0] to [1,1,1] in the core (bypassing sanity checks), now the checks will throw an exception for fixed-volume NpT; the original behavior was counter-intuitive and undocumented until 2 days ago
  • remove the automatic decay of NpT to NVT upon initialization of NpT with incorrect parameters
  • remove unused p_inst_av variable (average instantaneous pressure)
  • cleanup integrator documentation

Allow bool values in the script interface. The default value for
box dimension fluctuations is now [True, True, True] instead of
the counter-intuitive [0, 0, 0] that was implicitly converted to
[1, 1, 1] in the core.
Average instantaneous pressure: instantaenous pressure divided by
the number of steps in the integration (NaN if nsteps=0). Unused in
the core and observables, inaccessible from the Python interface.
When the NpT integrator is initialized with incorrect values, halt
script execution with an exception instead of initializing NVT.

3216: Refactor ghosts.cpp r=KaiSzuttor a=hirschsn

More refactoring that builds upon #3212 

Description of *major* changes:
 - remove GhostCommunication::mpi_comm as it is not used in ghosts.cpp,
 - make GhostCommunication::part_lists a std::vector,
 - remove static variables s_buffer and r_buffer,
 - factor out memory handling,
 - change loops to range based for,
 - use boost::mpi.
 - Replace the manual poststore and prefetch loops by find_ifs

Mainly, ghosts.cpp now defines CommBuf, which is a container for the data to be sent or received as well as two classes (Archiver and BondArchiver), that insert and extract the memory from CommBuf.

Some of these changes, like the removal of static variables, is necessary for my implementation of asynchronous ghost communication.

3253: Refactor NpT public interface r=fweik a=jngrad

Description of changes:

- remove the silent conversion of the incorrect input parameter `dimension=[0,0,0]` to `[1,1,1]` in the core (bypassing sanity checks), now the checks will throw an exception for fixed-volume NpT; the original behavior was counter-intuitive and undocumented until 2 days ago
- remove the automatic decay of NpT to NVT upon initialization of NpT with incorrect parameters

- cleanup integrator documentation


3258: CMake minor fixes r=fweik a=jngrad

Description of changes:
- change next milestone to 4.2
- load `GNUInstallDirs` to make standard GNU paths accessible from CMake variables
- simplify CMake logic and install in `python3.X` folder instead of the deprecated `python3` folder
- add extra check to make sure install paths are correctly configured (all python and shared object files must be inside the package `espressomd`)
