When searching a trust domain (set of tokens) for certs, NSS first puts all
matching certs from the cache into a collection.  Then, each matching cert
instance from a token is added to the collection.  When multiple instances of
the same cert are detected,  NSS forces a refresh of the CERTCertificate.

However, this also occurs when the same instance of a cached cert is detected. 
There is no need to refresh in this case, as we have just located the cached
instance we already knew about.

This has a side effect of not allowing the value of cert->trust to be set
temporarily, as the refresh constantly overwrites that value.

This patch makes it so that the trust is preserved, but I'm seeing *tons* of run
time asserts in PR_Calloc and PR_Free calls which leads me to believe something
funky may be happening with memory allocation/freeing as a result of this patch.

rev 2

That's what you get for asking for a patch late on Friday afternoon :)

There was something very obviously wrong with the last patch that I didn't see
before.  This patch implements the same idea, but (hopefully) correctly.  I
don't have a test case though.

rev 2


It seems clearer to rename the 'foundIt' parameter
'newInstance' (and reverse the true/false sense) or

Javi, could you test this patch?

Bob, could you review this patch, too?

the latest patch preserves the trust bits without throwing up all those
Assertions from within the memory allocator module.

rev 2

It looks OK, though I would like to make sure it doesn't break smart cards
before we officially bless it.

I just tested Ian's patch with a smart card with Bob
looking over my shoulder.

Ian, please go ahead and check in your patch on the
trunk.  After it passes QA on all platforms, we will
check it in on the NSS_3_7_BRANCH.
