`GetTimestamp()` "assumed" values it could not parse
to be a valid unix timestamp, and would use invalid
values ("hello world") as-is (even testing that
it did so).
This patch validates unix timestamp to be a valid
numeric value, and makes other values invalid.

Since Go 1.7, context is a standard package. Since Go 1.9, everything
that is provided by "x/net/context" is a couple of type aliases to
types in "context".
Many vendored packages still use x/net/context, so vendor entry remains
for now.
