Permissive dropbits/takebits allow segmentation faults

[GoogleCodeExporter]

Well, it's really the same as:
http://code.google.com/p/bitstring/issues/detail?id=16&can=1

If you pass dropbits/takebits a negative number of bits, then an attempted 
access to your bitstring will result in a segfault.

I don't know whether the stance here is that the user should make the tests and 
the library should be super fast, or that the library should be safe.

If safe is better, I attached a patch. :)
