Revised region management detects region conflicts by using _soft_
mappings per default. Overmapping is activated for population of managed
dataspaces only. For more information see header documentation of
base-linux/src/base/env/rm_session_mmap.cc.
Fixes#883.
To prevent multiple execution of main-bootstrap, I moved the code to a
statically initialized object. The reason for this change is that
_main() is exeuted twice when starting dynamic binaries. Now, the object
is part of the base-common library which is linked with ld.lib.so.
