Re-include pqsignal() in libpq.

tglsfdc · tglsfdc · commit b1fae823ee46 · 2013-03-17T15:45:31.000-04:00
We need this in non-ENABLE_THREAD_SAFETY builds, and also to satisfy
the exports.txt entry; while it might be a good idea to remove the
latter, I'm hesitant to do so except in the context of an intentional
ABI break.  At least we don't have a separately maintained source file
for it anymore.
