Converted recursion in GetPooledConnector() to iterative loop
Fix bug #152: NpgsqlInterval different constructors different ToString

Take the days from the Timespan, then the remaining ticks.
NpgsqlInterval(long) now calls NpgsqlInterval(TimeSpan) to make TimeSpan
do the division work.
Largely inspired by commit fd99912a019a3e987edfba8511431c82ec3cd9a5 from

Fix concurrent NpgsqlCopyIn usage.

Npgsql was using a singleton NpgsqlCopyIn but it couldn't be a singleton because there was state being exposed.
This state is the CopyFormat object which is different depending in the structure of the table being copied.
By using the same NpgsqlCopyIn object for all operations, when using two different NpgsqlCopyIn operations, they would interfere in each other causing problems.
