Stephan Wurm 8120223773 apps: ca,req,x509: Add explicit start and end dates options 
- Added options `-not_before` (start date) and `-not-after` (end date)
  for explicit setting of the validity period of a certificate in the
  apps `ca`, `req` and `x509`
- The new options accept time strings or "today"
- In app `ca`, use the new options as aliases of the already existing
  options `-startdate` and `-enddate`
- When used in apps `req` and `x509`, the end date must be >= the start
  date, in app `ca` end date < start date is also accepted
- In any case, `-not-after` overrides the `-days` option
- Added helper function `check_cert_time_string` to validate given
  certificate time strings
- Use the new helper function in apps `ca`, `req` and `x509`
- Moved redundant code for time string checking into `set_cert_times`
  helper function.
- Added tests for explicit start and end dates in apps `req` and `x509`
- test: Added auxiliary functions for parsing fields from `-text`
  formatted output to `tconversion.pl`
- CHANGES: Added to new section 3.4
