Fix deadlocks during initialization (#167)

- 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
