ENH: handle 64-bit memory information (#3060)

Browse Source 
- on large memory systems (eg, 6TB) the process information
  exceeds an 'int' range, so adjust parsing of the /proc/..
  to use int64

ENH: update/modernize OSspecific system information

ENH: minor update of profiling code

- std::string, noexcept, lazier evaluations

STYLE: use direct call of memInfo
