Subject: statusline: refactor to make it more customizable

Refactor statusline by clearly separating the rendering part from the
text display. Use printf-like format string for statusline
customization.

Document printf-like format string to customize the statusline.

Allow to completely mute the statusline (except for push notifications)
with a format specifier.

Provide a display mode with unicode icons for the status elements.

Implements: https://todo.sr.ht/~rjarry/aerc/34
