Add CUDA options to CMake.
* Add CUDA options to CMake, including adding CUDA_SRCS to each sub-directory's CMake list
* Changes so that HYPRE_config.h from CMake is consistent with configure
* Fix to license commenting style
* Add CUDA + CMake tests for building on lassen
This PR separates the jobs that break with --enable-mixedint (CGC, ParaSail, Euclid) from regular job scripts, so regression tests can selectively run jobs with --enable-mixedint. The new runtests<-option> files contain a list of tests for the runtest.sh
script that can be run by passing <-option> to the 'run.sh' autotest script. This should enable more flexibility for building regression test suites.
We should also revisit the notes pointed out by @rfalgout at some point.

This pull request adds a -save <ext> feature to the runtest.sh script to allow testing against different saved files on different platforms such as GPU machines. See Issue #255. A few additional things were done:
- All of the checks against the saved files were moved out of the individual tests and into runtest.sh.
- The output-file sanity checks that are in many of the tests were modified so they no longer depend on the saved files. Several issues were also uncovered and fixed.
This PR contains the support of UMPIRE pooling allocators for host and GPU memory. Configure hypre with --with-umpire, device and uvm allocations and deallocations are done with umpire, whereas host pool is not enabled by default. This PR also includes some other minor changes:
Adding .gitignore to the repo
Removing all malloc/calloc/realloc/free and regression testing on finding them
No longer compile ij.c with C++ compiler. It goes back to a C code now.
Introducing HYPRE_USING_GPU, which is equivalent to HYPRE_USING_CUDA || HYPRE_USING_DEVICE_OPENMP
Adding a few user-level interfaces: HYPRE_SetMemoryLocation, HYPRE_SetExecutionPolicy, HYPRE_SetGPUMemoryPoolSize and HYPRE_CSRMatrixSetSpGemmUseCusparse

* This commit has CUDA based smoothers for AMG based on the triangular parts of sparse matrices. This includes an Gauss-Seidel (relax_type==3), which uses CUSPARSE triangular solvers to invert L. Symmetric Gauss Seidel is implemented in relax_type==6 also via CUSPARSE. Finally, 2 new smoothers are added. THe first is a 2 stage approximation to Gauss Seidel using a parallel MatVec and L (relax_type==11). The second (relax_type==12) is a less effective version of 11. It uses A_diag instead of L for the smoothing. CPU implementations of these new smoothers are also provided. For the two stage algorithms, L and U are NOT explicitly created. This seems faster and saves memory. In the two stage preconditioner, multiply by invdiag rather than divide by diagonal reduces register pressure and yields full occupancy.

- Fixed improper inclusion of _hypre_utilities.h in user header files
- Added a 'check-headers.sh' regression test that compiles the examples with
options that output header usage, then checks for internal header files
- Moved HYPRE_Init() to 'HYPRE_utilities.h'
