Comment (by eschnett):

 Brief notes from the phone discussion:

 - rename TLS to THREAD_LOCAL (both macro and include file)
 - define CCTK_THREAD_LOCAL via autoconf magic, choose whether to use this
 macro depending on whether AMPI is used
 - add documentation for Enable/DisableThreadLocal
 - simplify logic for redirecting I/O: don't introduce another else branch,
 rather move #ifdef into else branch
 - declare CmiEnableTLS only when AMPI is available
 - why is mpi.h needed for flesh.cc?
 - don't use -DCCTK_TLS in option list
 - don't use -DCCTK_HAVE_AMPI in option list; rather set this in AMPI thorn
