- update to 5.5:
* check program:
- Multiple exit values can be tested within single program check
- Exit value test supports multiple cycles option ("for X cycles")
- If exit value test matches and the stderr has no data, try stdout
* Renamed mail header (message-id and mime-version) to prevent
triggering spam check of capitalization.
* The 'check system ' statement sets the system hostname in mail
alerts and initial hostname in M/Monit.
* Increase the default mailserver timeout to 30 seconds.
* Fix the rare hung on linux which may occur during program execution.
* In the case that the process start/restart execution failed, monit kept
"Execution failed" flag even if the process was recovered later (for
example it was starting slowly or manually recovered).
* Fix the mail alert (strict SMTP implementation) to pass MTA-side sanity
checks like postscreen.
* The -t option tests the configuration file syntax even if the
file permissions are wrong.
* Do not display the default non-existence test for the check
program (not applicable in the check program context).
