Refactor set of routines specific to elog.c
This refactors the following routines and facilities coming from
elog.c, to ease their use across multiple log destinations:
- Start timestamp, including its reset, to store when a process has been
started.
- The log timestamp, associated to an entry (the same timestamp is used
when logging across multiple destinations).
- Routine deciding if a query can be logged or not.
- The backend type names, depending on the process that logs any
information (postmaster, bgworker name or just GetBackendTypeDesc() with
a regular backend).
- Write of logs using the logging piped protocol, with the log collector
enabled.
- Error severity converted to a string.
These refactored routines will be used for some follow-up changes
to move all the csvlog logic into its own file and to potentially add
JSON as log destination, reducing the overall size of elog.c as the end
result.
