- More to come in later commit, below is just tidying some stuff up
- clang-tidy
- mpi_gotcha quiet about not finding funcs
- update to new papi config
- sampling block_samples / unblock_samples
- disable calling component's sample functions within sampler
- release doesn't strip library
- remove HSA and ROCP env variables from modulefile / setup-env
- preliminary support for LD_PRELOAD usage
- default sampling rate is 300 interrupts / second
- fixes various deadlock issues at startup
