#36 Overloaded semantics of DK_STAT_SYNTAX

[Mark Martinec]

In libdk/dk.c there are 11 different types of
failures, each resulting in status DK_STAT_SYNTAX,
yielding a not-too-helpful and all-too-familiar:
"syntax error in signature data"

(including a case of a missing From: header field
while signing because of mistakenly including a "from"
in option -o, which took way too long to diagnose)

For the sake of maintainability and troubleshooting,
please change the code to report cause of failures
more specifically.

libdkim is much more detailed about each use of overloaded return codes. I'm planning to port that facility back into libdk as well.

Done for the next version. There's a new API function called dk_geterror() which can be used to extract a more detailed error message from libdk when an error code is returned by one of the main libdk functions.

v0.5.0 released, containing dk_geterror(); dk-filter now makes use of this
