* Updated documentation for clarity and to clean up a few typos.
* Add warning messages to FEI, ParaSails, PILUT, Euclid.
* Improved and updated GPU information
* Added CMake build information
* Add hypre_State type to track initialization state of hypre
* Add HYPRE_Initialized to determine whether hypre has been initialized
* Add HYPRE_Finalized to determine whether hypre has been finalized
* Add private implementations for hypre_initialized/finalized
* Add HYPRE_Initialize
* Update Fortran interface for HYPRE_Initialize
* Use HYPRE_Initialize in test drivers and examples
* Clean-up mentions of HYPRE_Init
* Add HYPRE_DEPRECATED macro to autotools and CMake builds
* Add regression test for library initialization/finalization
This PR adds a new variable in `HYPRE_config.h` for naming the hypre's branch currently in use. Internal drivers have been updated to use this variable
* Add HYPRE_BRANCH_NAME to Makefile and cmake builds
* Run config/update.sh
* Ignore files generated by cmake in the cmbuild folder
* Update drivers
* Update regression tests
Thir PR adds a factorized sparse approximate inverse (FSAI) implementation on hypre, which can be used as a standalone solver, preconditioner to Krylov methods, or complex smoother to BoomerAMG. Particularly, we consider the adaptive algorithm version, where the sparsity pattern of the lower triangular factor G is built dynamically, i.e., during an iterative procedure that tries to find the best nonzero positions for a given row of G. This implementation was performed on top of the IJ interface. It uses the diagonal portion of A for constructing G, i.e., it's a block-Jacobi method in the MPI sense. List of additional changes:
* Add caliper instrumentation to FSAI.
* Add ZeroGuess option to FSAI.
* Performance optimizations.
* Add OpenMP support to FSAI.
* Make internal BLAS/LAPACK functions thread-safe.
* Update CMake build.
* Add new test cases: beam_tet_dof459_np1, beam_hex_dof459_np2, and beam_tet_dof2475_np4.
* Add documentation for FSAI.

This PR extends the (semi)-struct matrix/vector IO functions added on #583 with GPU support. Additionally:
* Fix regression tests on Lassen.
* Read data values into host memory
* Update Umatrix read algorithm when the ParCSRMatrix is expected to live on the device
* Reset deallocated pointers at hypre_IJMatrixDestroyParCSR to NULL
* Clone rownnz info if present on a CSRMatrix
* Reduce memory transfer and remove unused variables
* Fix bug with -print option
* Build rownnz info also when the ParCSRMatrix is in assembled state
* Remove a few instances of "return ierr"
* Refactor (s)struct IO - code works with cuda and without UM
* Add executables to gitignore
This PR changes AMG defaults regarding GPUs at various places, adds regression tests on GPUs, simplifies CUDA boxloop implementations.

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
