Juan Lang 3bf9c165fa Correct a test that incorrectly showed signed certs couldn't be added 
to a mem store.
Support signed certs in mem stores.
Correct use of a freed pointer.

* FIXME:
* - As you can see in the stubs below, support for CRLs and CTLs is missing.
* Mostly this should be copy-paste work, and some code (e.g. extended
* properties) could be shared between them.
* - Opening a cert store provider should be morphed to support loading
* external DLLs.
* - The concept of physical stores and locations isn't implemented. (This
* doesn't mean registry stores et al aren't implemented. See the PSDK for
* registering and enumerating physical stores and locations.)
* - Many flags, options and whatnot are unimplemented.
