add a bunch of bindings/new definitions of unimplemented MPI-2 functions, to make bigdft happy again
add limiter_link option to cluster tag, to add a pseudo-shared link, to limit bandwidth reachable with a fullduplex link
add a loopback_lat and loopback_bw to cluster tag
update dtd
add a cfg:tracing/smpi/internals option, to trace all pt2pt communications during a collective one
This provide a better view of the pattern, useful for debugging
switch back from two underscores to one in fortran names, to allow linking with external libs
remove states for the new tracing option, as only links are really useful
freebsd compatibility
new attempt to stabilize the use of underscores on f90/f77/f2c
