* use correct MPI initialization method
rocSHMEM requires that the MPI library is initialized using
THREAD_MULTIPLE support. Lets use that function therefore in our
examples.
* Update examples/rocshmem_init_attr_test.cc

[ROCm/rocshmem commit: 2e01af22ca]
* add code for bootstrapping
the bootstrapping code has been extracted from the MSCCLPP library,
which in parts is based on the code from NVIDIA. The code has been
modified to match the specific requirements of the rocSHMEM library.
* add code to use the new uniqueId bootstrapping
* adjust init_attr example
extend the rocshmem_init_attr example to use two disjoint groups
of processe, in order to trigger the new code path.
* add env variable for bootstrap timeout
* Update examples/rocshmem_init_attr_test.cc

[ROCm/rocshmem commit: b5830a623b]
* Update the naming convention for collective APIs to ensure consistency across the interface.
* Move all collective API declarations to rocshmem_COLL.hpp
* The following APIs were updated as part of this change:
- `barrier`
- `barrier_all`
- `sync`
- `sync_all`
- `all_to_all`
- `broadcast`
- `fcollect`
- `all_reduce`
* Update header file generation code for collective APIs
[ROCm/rocshmem commit: 68421895d6]
add the interfaces required to support rocshmem initialization
through the uniqueID mechanism. At the moment this still maps to
MPI initialization underneath the hood, but adding the functions might
simplify the porting of some applications to rocshmem. In addition, if
we need to transition away from MPI one day, this is also one step into
this direction.
[ROCm/rocshmem commit: e9f6227d75]
* Rearrange CMakefile
* Enable linking to external rocshmem library
* Minor fix for the functional test driver
* ROCSHMEM_HOME detection fixed
[ROCm/rocshmem commit: 96424a59a8]
* Change log_stride calcualtions to stride calculations
* Update all_reduce example code to use team based interface
