Improve style guideline compliance of assorted error-report messages.

Browse Source 
Per the project style guide, details and hints should have leading
capitalization and end with a period.  On the other hand, errcontext should
not be capitalized and should not end with a period.  To support well
formatted error contexts in dblink, extend dblink_res_error() to take a
format+arguments rather than a hardcoded string.
