Enhance bindings for Crypt32 and fix bindings for array attributes #1252

Merged

The implementations of the rgAttribute, rgCTLEntry and rgExtension
attributes are not in line with the observed behaviour of the API. At
least in part they are documented to be pointers to arrays of pointers
to structures. This is not correct, as segfaults were observed and
testing shows, that they are in fact pointers to arrays of structures.

In addition it was observed, that the bindings of CTL_INFO#getRgCTLEntry
and CTL_INFO#getRgExtension method names were inverted.

The bindings for CERT_EXTENSIONS#getRgExtension and
CTL_INFO#getRgExtension are untested as but assumed to be implemented
identically to the tested bindings.

The functions

  • CertEnumCertificatesInStore
  • CertEnumCTLsInStore
  • CertEnumCRLsInStore
  • CryptQueryObject

from c.s.j.p.win32.Crypt32 were bound to be able to excercise the
accessors.

This changeset changes method signatures, but you'd need to be blind to use the methods in the way they were originally bound. They are obviously broken and thus from my POV don't form an api break.

Looks good to me. A few typos and questions more for my education than concern that they are wrong.

Looks good from my point of view. I have not yet had time to actually test it, but I have looked closely at the code!

@dbwiddis thank you for your review. I'll merge this in now, if you recognize a problem later (preferably before the next release) just speak up and I'll revisit.
