Subject: [PATCH] parse_time_interval: Allow negative time in settings
This splits sign parsing out of parse_time_interval_uint() so that the
negative sign is applied outside of the unsigned context where the
number parsing is done, and after all the checks that it's lower than
(1 << 31)
This fixes issues with settings like `server_reconnect_time`,
`server_connect_timeout` and `lag_max_before_disconnect`, which accepted
-1 as a valid value.
