and decremented the refcounts of list member tuples along with the list

It's cheaper to change only the list refcount.  When we are considering
deleting a cache entry, we have to check not only its own refcount but
its parent list's ... but it's easy to arrange the code so that this
check is not made in any commonly-used paths, so the cost is really nil.

I was bit hasty making the random exponent 'k' a prime.  Further researh
shows that Elgamal encryption has no specific needs in respect to k,
any random number is fine.

It is bit different for signing, there it needs to be 'relatively prime'
to p - 1,  that means GCD(k, p-1) == 1, which is also a lot lighter than
full primality.  As we don't do signing, this can be ignored.

This brings major speedup to Elgamal encryption.

There is a choice whether to update it with pgp functions or
remove it.  I decided to remove it, updating is pointless.

I've tried to keep the core of pgcrypto relatively independent
from main PostgreSQL, to make it easy to use externally if needed,
and that is good.  Eg. that made development of PGP functions much
nicer.

But I have no plans to release it as generic library, so keeping such
doc
up-to-date is waste of time.  If anyone is interested in using it in
other products, he can probably bother to read the source too.

Commented source is another thing - I'll try to make another pass
over code to see if there is anything non-obvious that would need
more comments.

Here we go, that wasn't too hard :-)

Apart from adding the error handling, it does one more thing: it changes
the errormode when loading the DLLs. Previously if a DLL was broken, or
referenced other DLLs that couldn't be found, a popup dialog box would
appear on the screen. Which had to be clicked before the backend could
continue. This patch also disables the popup error message for DLL
loads.

I think this is something we should consider doing for the entire
backend - disable those popups, and say we deal with it ourselves. What
do you other win32 hackers thinnk about this?

In the meantime, this patch fixes the error msgs. Please apply for 8.1
and please consider a backpatch to 8.0.
