Rework process field print functions 

Make functions formatting data for a process field column less error
prone, unify interfaces and improve some internals.

* Process_printBytes
  - rename from Process_humanNumber
  - take number in bytes, not kilobytes
  - handle petabytes
  - increase buffer to avoid crashes when the passed value is
    ~ ULLONG_MAX

* Process_printKBytes
  - add wrapper for Process_printBytes taking kilobytes keeping -1 as
  special value

* Process_printCount
  - rename from Process_colorNumber

* Process_printTime
  - add coloring parameter as other print functions
  - improve coloring and formatting for larger times

* Process_printRate
  - rename from Process_outputRate
  - use local buffer instead of passed one; this function prints to the
    RichString after all
