Robin Jarry a1f779ccc9 logging: add logger system with levels
The built-in logging system is rather basic. Implement a multi-level
logger to ease interpreting the logs. Configure the loggers with
prefixes and microsecond precision for timestamps.

Also, prefix the messages with the source file name and line number.
Because of this, enabling the logs has a performance cost. They will
only be enabled when redirecting aerc stdout to a file.

Here is an example output:
