Add flag 'is_de_vs' to decryption results and signatures.

* NEWS: Update.
* lang/cpp/src/decryptionresult.cpp (DecryptionResult::isDeVs): New
function.
* lang/cpp/src/decryptionresult.h (DecryptionResult::isDeVs): New
prototype.
* lang/cpp/src/verificationresult.cpp (Signature::isDeVs): New
function.
* lang/cpp/src/verificationresult.h (Signature::isDeVs): New
prototype.
* lang/python/src/results.py (DecryptResult): Turn field 'is_de_vs'
into a boolean.
(Signature): Likewise.
* src/decrypt.c (_gpgme_decrypt_status_handler): Handle the new
compliance status line.
* src/verify.c (_gpgme_verify_status_handler): Likewise.
* src/gpgme.h.in (gpgme_status_code_t): Add new status codes for the
new status lines.
* src/keylist.c (parse_pub_field18): Move function to 'util.h'.
(keylist_colon_handler): Adapt callsites.
* src/status-table.c (status_table): Add new status lines.
* src/util.h (PARSE_COMPLIANCE_FLAGS): New macro.  This used to be
'parse_pub_field18', but turned into a macro to make it polymorphic.
