Parse more strictly integer parameters from connection strings in libpq
The following parameters have been parsed in lossy ways when specified
in a connection string processed by libpq:
- connect_timeout
- keepalives
- keepalives_count
- keepalives_idle
- keepalives_interval
- port
Overflowing values or the presence of incorrect characters were not
properly checked, leading to libpq trying to use such values and fail
with unhelpful error messages. This commit hardens the parsing of those
parameters so as it is possible to find easily incorrect values.
