- checkRotate() notes the reason for rotation
- rename a few variables
- rename some macros and introduce a few more

- remove 'now' from status struct. We only need it locally.
- add 'static' to function declaration, although the code
  is still in a single file
- change signature of get_now()
- make argument count check easier to understand

using HUP and INT signals to the rotatelogs process.

This is helpful, when log activity is low, but you want
rotatelogs to close the open log files.

SIGHUP triggers checking the rules given during startup,
SIGINT forces rotate independently form those rules.

When the signal triggers a rotation, the open file
is closed immediately. The new file is opened when
new log data arrives, or in case "-f" was given it
is opened immediately.

Based on my patch in BZ 44427.

Note on Windows: The new functionality is undefined when
SIGHUP or SIGINT are not available. Does the use case
make sense on Windows? If so, which signals should we use?

Mainly cleanup plus correct decision in checkRotate()
if status->nLogFD is NULL.

- Fix compilation error
- set correct time when forcing log file open
  on startup

of signal triggered log rotation.

- move code into new functions checkRotate() and doRotate()
- bundle config data and runtime data in two structs to
  allow easier passing to functions
- Simplify bypass_io logic as a first use case for doRotate
  and rename flag to force_open to reflect the new logic
