Updated sendfiles(1):
1) Added -from switch.
2) sendfiles will now construct a From address, using the sender's
   localmbox, if the user does not specify it with -from or the PERSON
   environment variable.
3) Added support for bzip2, lzma, and zip compression methods.  Added
   a new switch to select the method:  -compress <method>.  Because
   support for the old -compress with was broken (it did not use
   -c with compress/uncompress) and it was undocumented, it has
   been replaced.  Retained old -gzip and -none switches for backward
   compatibility even though they were undocumented.
4) Allow the recipient argument to be preceded by the optional -to
   switch iff the subject argument is preceded by the optional
   -subject switch.  Allow the delay value to be specified using the
   optional -delay switch.
5) Added -version and -help switches.
6) All switches can now be abbreviated.

/etc/sendfiles no longer needs to be configured.  It's easier to
support make distcheck by having it figure out its path at runtime.

In viamail, set postproc to post in the same directory as itself, if
invoked with a full path.  This allows it to support make distcheck.
viamail does not read the profile so its postproc is otherwise
hard-coded at compile time.

Added test-sendfiles.
