Database: purge old reports. Or big reports. Or both.

We should have a way to clean things up in the database.

I think that there should be something that operates on the database that 
accepts multiple rules that can be expressed in the form rule = (older_than, 
max_db_size). The cleanup would proceed as:

  for each rule in rules:
    for each report in sort(reports, oldest_first)
      if database_size < rule.max_db_size:
        break
      if report.age > rule.older_than:  // if report.age is negative beyond a threshold, treat it as 0?
        break
      report.purge

Then we could specify rules like

(0, 4 * 1024 * 1024 * 1024)  // always keep below 4GB
(60 * 60 * 24 * 7, 1 * 1024 * 1024 * 1024)  // purge week-old reports to keep 
below 1GB
(60 * 60 * 24 * 7 * 4, 512 * 1024 * 1024)  // purge 4-week-old reports to keep 
below 512MB

crashpad_handler can run the purge task periodically.
