This enhances what print_level can achieve in MGR. Particularly, now we can dump linear system info to files according to the print_level code. We also have the ability now of printing a sequence of linear systems to file (useful when hypre is used in time-stepping application).

This solves an out-of-bounds memory error during `hypre_BoomerAMGSetup` when called multiple times without a call to `hypre_BoomerAMGDestroy` interleaved. This pull request makes sure that `smooth_num_levels` is reset to `hypre_ParAMGDataSmoothNumLevels(amg_data)` before the smoothers variable is allocated.

* Change char sizes to HYPRE_MAX_FILE_NAME_LEN
* Add options to IJ driver for reading binary matrices/vectors
* Add regression tests for IJ input/output
Allow the use of MAGMA as local linear solver for FSAI.

Add warnings for Euclid and PILUT redirecting users to hypre-ILU.
Rewrite hypre-ILU overview section.
Add new sections to hypre-ILU documentation: "User-level functions", "ILU as smoother for BoomerAMG", and "GPU support".
Include info about new iterative ILU options.
Update BoomerAMG complex smoothers section.
Change name "hypre-ILU" to "ILU"
Modified from #718, this PR squashes out zero columns of the off-diagonal part of a `hypre_ParCSRMatrix`.
The issue was in offd there exist empty columns (columns with no nonzeros), which correspond to "useless" entries in col_map_offd. This caused issues in at coarser grids in the communications with large number of ranks. We added a routine to compress the zero columns out and shorten col_map_offd. This should reduce communication cost even at higher levels.
Two sources of the empty columns have been located and fixed:
- Truncation after building P
- P^T(AP): only the transpose multiplication part.

This allows users to direct hypre's error messages to a memory buffer instead of stderr. With this, there are now three basic ways to use hypre when configured --with-print-errors:
- Default (mode 0): Errors are printed immediately to stderr (there is no processor information available in this print).
- Store errors in memory (mode 1) and call PrintErrorMessages to print them.
- Store errors in memory (mode 1) and call GetErrorMessages to manage the error messages however you like.
* Use unroll_factor=8 for rocm-5.4.3
* Add SortCSRRocsparse back
* Fix Wunused-variable warnings
* Set _hypre_memory_tracker to NULL after destroy
* Update tioga results after changing default rocm version to 5.2.0
