mail/fetchmail: avoid rc.conf overriding daemon interval, many other fixes

Authors: CH = Corey Halpin, MA = Matthias Andree

- fetchmail's rc script now queries the daemon interval from the
  configuration, and falls back to the rc.conf value if given. [CH]
- Similarly, the logging facility will be taken from the configuration [MA]
- Add documentation to the rcfile's header comments. [MA]
- Drop support for fetchmail_home_prefix in rc.conf, and query the
  respective users' home directories with getent instead. [MA]
- In the rc scripts, redirect input from /dev/null so it will not ask
  for passwords. [MA]
- Add support for the typical 12.1 rc.conf ${name}_... keywords. [MA]
- Make script execution easier to follow by simplifying if...else logic. [CH]
- Fix rcscript's exit code to be 1 if one of the per-user calls fails. [CH]
- Add relevant notes to UPDATING. [MA]

+
+  Note that if you are using fetchmail in a multi-user setup, i. e. with the
+  fetchmail_users (mind the -s!) variable set, the $fetchmail_home_prefix +
+  user second-guess work has been replaced by a real lookup of the user's home
+  directory. In the majority of configurations, this should not make a
+  difference, in some setups, it may open up some flexibility.
+
+  The fetchmail_home_prefix variable is ignored from 6.4.12_1 onwards.
+
+  Also, the rc script redirects its input from /dev/null so that passwords
+  will not be interactively queried from an rcfile.  Put passwords into
+  the [.]fetchmailrc or into a .netrc file.
