Merge branch 'framework/recursive_log_write' into hotfix-v6.2 (PR #181)

This merge adds the 'recursive' attribute to the MPAS_log_write routine.

The MPAS_log_write routine can generate indirect recursive calls to itself,
for example, when MPAS_log_write calls log_abort, which calls MPAS_log_finalize,
which then calls MPAS_log_write. Without the recursive attribute, several
compilers will halt execution when MPAS is compiled with DEBUG=true
if a recursive call is detected in a routine not marked as recursive.

* framework/recursive_log_write:
  Add missing 'recursive' attribute to MPAS_log_write(...) routine
