Existing log code was outputting 'connecting new client' twice and saying 'new client connected', creating a false impression when an error (like a timeout) was present.
This happened to work before because `Query.portalName` was undefined,
but in order to be able to set the portal explicitly it should be using
`Query.portal`.
This commit adds some finer grained detail to handling the postmaster's
response to SSL negotiation packets, by accounting for the possibility
of an 'E' byte being sent back, and emitting an appropriate error.
In the naive case, the postmaster will respond with either 'S' (proceed
with an SSL connection) or 'N' (SSL is not supported). However, the
current if statement doesn't account for an 'E' byte being returned
by the postmaster, where an error is encountered (perhaps unable to
fork due to being out of memory).
By adding this case, we can prevent confusing error messages when SSL is
enforced and the postmaster returns an error after successful SSL
connections.
This also brings the connection handling further in line with
libpq, where 'E' is handled similarly as of this commit:

Given that there are no longer pre-7.0 databases out in the wild, I
believe this is a safe change to make, and should not break backwards
compatibility (unless matching on error message content).
* Replace if statement with switch, to catch 'S', 'E' and 'N' bytes
returned by the postmaster
* Return an Error for non 'S' or 'N' cases
* Expand and restructure unit tests for SSL negotiation packets
The support for the `noAssert` argument dropped in the upcoming
Node.js v.10.x. All input is then validated no matter if this
is set to true or not. Just remove the argument because of that.
PostgreSQL 10 reports its version as only `major.minor`, so it can’t be parsed with semver. The `server_version_num` setting is a major version followed by a four-digit minor version since version 10, and was a three-digit major version followed by a two-digit minor version before that.
Changes the Makefile lint target to use the local copy of
eslint that would be installed in node_modules rather than
a global copy that may not be installed.
