- Port the guile-2.0 interface of mailutils-3.4 back to mailutils-3.5
as it seems that guile-2.2 is currently not doable

- Move guile site files into main package here there is the guimb
scheme script file
- Repair ghost links used by update-alternatives
- Temporary disable guile as there is currently no guile-2.2

- Update to mailutils 3.5

+ mu-encoder-port port name . args
+ mu-decoder-port port name . args
+ mu-header-decode hdr [charset]
+ mu-header-encode hdr [encoding [charset]]
* Introduced support for Python 3.x
* Define sieve variables from the command line
The sieve utility now allows you to supply initial values for
RFC 5229 variables using the --variable command line option, e.g.
sieve --variable mailbox=outgoing
* Support for Berkeley DB versions 5 and 6
* headline variable in the mail utility
The new %D specifier has been implemented, which allows the user to
supply arbitrary strftime(3) format string for outputting message
date/time. E.g.:
set headline="%4m %20D{%Y-%m-%dT%H:%M:%S} %18f %s"
In simplified form, %D can be followed by a single time format
specifier. E.g. %DH can be used instead of %D{%H}.
