Commit-type: documentation

Only makefiles in the test and tutorial directories need lib/petsc/conf/test

Commit-type: housekeeping

Switch to clang-format 16

Merge remote-tracking branch 'origin/release'

ISLocate_Block: fix incorrect dimension

Deprecate ISCompressIndicesSorted()

ISCompressIndicesGeneral: special path for ISBLOCK

HDF5: Use correct default

Docs: more cleanup

Fix manual pages based on reports from Jacob's lint tool

Clean up PETSc str ops to use more secure implementations where possible. These include:

- Use PetscStrncpy()/PetscStrlcat()/PetscMemcpy() over PetscStrcpy()/PetscStrcat()
- Use PetscArraycpy() over

Clean up PETSc str ops to use more secure implementations where possible. These include:

- Use PetscStrncpy()/PetscStrlcat()/PetscMemcpy() over PetscStrcpy()/PetscStrcat()
- Use PetscArraycpy() over PetscMemcpy() as appropriate for string buffer copying
- Use built in string from name over hardcoding
- Use sizeof over hardcoded length
- Replace some Strlcat with Strncpy when offset is known
