When we get a duplicated certificate, treat it as a failure and increment the download count. Do not claim to be downloading certificates that we merely want.

introduction points.
- Fix uninitialized size field for memory area allocation: may improve
memory performance during directory parsing.
- Treat duplicate certificate fetches as failures, so that we do
not try to re-fetch an expired certificate over and over and over.
- Do not say we're fetching a certificate when we'll in fact skip it
because of a pending download.
