Fix small bug with periodic boundary conditions

This fixes a small bug that can affect simulations with periodic boundary conditions in parallel (the conditions for triggering this bug seem extremely particular).

Force fftw to use the correct compiler

This is a small change to guarantee that we use the correct compiler to build fftw.

Fix missing dependency on openmpi-bin for DEB packages.

This MR fixes the missing openmpi-bin dependency, which is required for packaged executables to run (even in serial without mpirun).

See merge request !630

Small fix to make DriverAdaptive more general

This is a small fix to avoid getting an error in DriverAdaptive when there is no NekManager for GlobalLinSys.

I think it is possible that after this change DriverAdaptive will work with solvers other than IncNavierStokes (if they support variable P, of course).

Do not package tutorials into source package.

The MR just disables the tutorials repository from being included in the Nektar++ source packages if the submodules are cloned in the working directory.

Fix/single mode

This MR fixes the linearised advection operators to work correctly with stability analysis using a full complex single mode.

Fix for Debian shlibdeps not being called.

This MR fixes a regression in the Debian packaging which results in the package dependencies not being calculated with dpkg-shlibdeps.

Extend some meshing modules to 2D

This MR extends the functionality of NekMesh in 2D:
- The cyl module now works in 2D. The cylinder center can now be passed as a parameter, instead of always being at the origin.
- The boundary layer module is extended to Quads.
- A new module was created that generates curved edge information in 2D based on a prescribed function y=f(x).

Removed incorrect constraint requiring base flow to be 2D2C for SM.

Fix 3DH1D copy constructor for boundary extraction

This MR introduces a new constructor for ContField3DHomogeneous1D, providing a proper fix for the FieldConvert extract module in this case (this only worked by avoiding the copy constructor). We still need to forced Field.hpp to use a valid variable name, since using DefaultVar would lead to a field with no boundary expansions.

Fix mpi problem when terminating after finding NaN.

This fixes a bug causing the simulation to hang when only some of the mpi processes encounter a NaN.

See merge request !605

Move executable name override to TestData class.

This MR moves the parsing of a command-line override of the executable to use for a test into the TestData class so we do not expect an tag in the .tst file.

Fix problem in QuadExp with different number of points per direction

This fixes a few bugs in `QuadExp`, which prevent simulations using quads from working when the number of points is not the same in both directions.

See merge request !607

Fix/compressed io seg curved

Provide a fix to issue #24 where extracting a 1D manifold from a 2D mesh did not contain curvature when the file was in compressedIO format. This was due to an incorrect reference to a face map rather than an edge map. 

See merge request !619

fix lapack call

This fixes a small bug in the lapack call for eigensolve of full nektar matrices. Previously it was not assigning enough room in memory for lapack
