* unify handling of env variables
create a class containing all (most?) environment variables used by rocshmem and an object that is instatiated
before library_init, since some of the environment variables need to be
set before we start the bootstraping process.
This allows us to remove two files from the bootstrap directory.
* replace INFO and TRACE macros with DPRINTF
to be more consistent with the rest of the rocSHMEM code
[ROCm/rocshmem commit: db74307195]
* Remove unused forward_list
* Remove unused __read_clock function
* Replace wallClk code with hip function
* Remove unused unit test for ipc
* Remove slab heap
* Remove unused EBO spinlock
[ROCm/rocshmem commit: 0fd628458c]
This PR addresses two issues:
- reduce the number of contexts supported by the host-interface by
default to 1, we are not using those at the moment, and hence
we now create fewer MPI_Win at the startup
- introduces a micro-sleep in RO progress engine in case there are no
pending requests. This leads significant performance improvements
observed for inter-node communication with THor2 NICs.
