Remove get_chksum to hush warnings

This popped up because Fedora mandates warning-free builds,
and get_chksum triggers a warning because it returns an
unaligned pointer (it is so analigned, static analysis in
the compiler can detect it).

The easiest fix is to remove it altogether. We think it should
be safe, because:

 - The function is not listed in any headers
 - Its counterpart is called "set_checksum", not "set_chksum"
 - PyECLib does not use it

We also hush some doxygen warnings about wrong comments.
