seem to change much when compiled with optimization (besides the shorter
code), but leads to a 50% run-time reduction when compiled without
optimization.

* use test(i) to get the value of a bit instead of getBit(i), this
  method work for bitset and BitSetVectorConstReference

[[Imported from SVN: r5801]]

* add more tests, some of them fail atm.

[[Imported from SVN: r5800]]

* update Makefiles and configure

* add using statement to fix inaccessbility of "operator[] const"

[[Imported from SVN: r5367]]

* add operator= for Reference

* make iterators only forwarditertors
* remove method getLocalBits
* new methods count and countmasked superseed nSetBits
* nSetBits marked deprecated, but will stay for a possible
  replacement of BitField by BitSetVector<1> (see #456)
* updated test to run the whole iterator test
* fulfill the whole bitset interface
