Promote code common to both ECDSA* cores to separate repository in core/ tree.

Pavel's two ECDSA base point multiplier cores share a fair amount of
code.  Maintenance issues aside, the duplication confused the Xilinx
synthesis tools if one tried to build a single bitstream containing
both cores, so we've separated the common code out into this library.

The selection of files in this library was done by comparing the rtl
trees of the two original core repositories using "diff -rqws" and
selecting the files which diff reported as being identical.

Also dealt with some cosmetic issues (indentation, Windows-isms, etc).
