Xi Luo e65fa4ff5c Bring ADAPT collective to 4.1
This is a meta commit, that encapsulate all the ADAPT commits in the master
into a single PR for 4.1. The master commits included here are:
fe73586, a4be3bb, d712645, c2970a3, e59bde9, ee592f3 and c98e387.

Here is a detailed list of added capabilities:
* coll/adapt: Fix naming conventions and C11 atomic use
* coll/adapt: Remove unused component field in module
* Consistent handling of zero counts in the MPI API.
* Correctly handle non-blocking collectives tags
  * As it is possible to have multiple outstanding non-blocking collectives
    provided by different collective modules, we need a consistent
    mechanism to allow them to select unique tags for each instance of a
    collective.
* Add support for fallback to previous coll module on non-commutative operations (#30)
* Replace mutexes by atomic operations.
* Use the correct nbc request type (for both ibcast and ireduce)
  * coll/base: document type casts in ompi_coll_base_retain_*
* add module-wide topology cache
* use standard instead of synchronous send and add mca parameter to control mode of initial send in ireduce/ibcast
* reduce number of memory allocations
* call the default request completion.
  * Remove the requests from the Fortran lookup conversion tables before completing
    and free it.
* piggybacking Bull functionalities
