Okay, I've had it with mktime() bugs. While chasing Torello Querci's
recent gripe, I discovered not one but two undocumented, undesirable
behaviors of glibc's mktime. So, stop using it entirely, and always
rely on inversion of localtime() to determine the local time zone.
It's not even very much slower, as it turns out that mktime (at least
in the glibc implementation) also does repeated reverse-conversions.

That patch needed some work: it assumed the sqlcode in a server message was

patch missed a couple of places where server errors where being received.
In addition to fixing the above, I also added full support for the V3 protocol
error message syntax, I reversed the order of arguments in the PSQLException
constructor to more closely follow the constructors for SQLException, I changed
the new constructors that take PSQLState to take Object for additional
parameters as the old ones did.
Still todo are to add SQLState values to all existing exceptions thrown in the
