f4feca27e5 Use ebloom by default 
This commit changes the default bloom filter to
be basho’s bloom, which is significantly more
stable w.r.t. performance.  The code can still
read the old bloom filters; new files are written
with the new filters.

The default is controlled in src/hanoidb.hrl
using the USE_EBLOOM macro.

697683240d Make ebloom / scalable bloom a compile-time option 
bloom (from basho) uses a NIF implementation which
may be faster and use less memory; test before use.

The “old” bloom, a.k.a. “scalable bloom” 
is pure erlang, which also has nice properties. 

Note!  Switching to ebloom changes the file format
so the default is still to use ‘scalable bloom’.

923dbe3852 Fix typing for bit array representation 
For now we keep the bit array representation code
around in case someone has bloom filters
persisted that use this representation. Going
forward we should remove this from the code.

This is a large change set, which adds type specs

need even more type specs as we move forward.
