Improved logging

New python version.

Implemented current style guide for backends (i.e., config.py and explicit logging)

improve logging, fix for erlexec's required env HOME, use pfexec to run tests as noaccess:noaccess if env var USE_RCTL is set; if env var USE_RCTL is set, let Solaris guard resources (cpu time, mem) instead of the timer with a fixed period in user space

execute /usr/bin/newtask aka invoked copiler/interpreter with uid=noaccess and gid=noaccess

use value-by-ref to access global config vars, fix typo in Spooler

- add env var USE_RCTL to get tests running on Solaris machines, which have not defined the appropriate projects (i.e. uses newtask if set only) - startup/env_iws.tcsh - no need to adjust backends/**/*.sh anymore

use ksh instead of fast sh with reduced features

fix logging system add resource ctrl to scripts

- incompatible changes: - backendctl::_startBackend() now requires backendHost as param as well - new features: - additional command line options to be able to set parameters for each spooler/backend individually - overwrite default settings in config.py - separate logfile per backend - Solaris Service Fault Management (SMF) support - see startup/ - misc fixes: - try to set euid only, if started with UID == 0 aka root - config.py: don't duplicate messages to event.log, i.e. fH disabled
