Update to 0.4.7.

Noteworthy changes in version 0.4.7 (2004-04-29)
------------------------------------------------

 * Correctly initialize the fields expired, revoked, invalid, and
   disabled in the gpgme_key_t structures.

 * A bug fix: The flag wrong_key_usage of gpgme_signature_t was
   accidently of type int instead unsigned int.

Noteworthy changes in version 0.4.6 (2004-04-06)
------------------------------------------------

 * Bug fixes

Noteworthy changes in version 0.4.5 (2004-03-07)
------------------------------------------------

 * GPGME is now compiled with LFS (large file support) by default.

 * New key listing mode GPGME_KEYLIST_MODE_VALIDATE for validation of
   the listed keys.

 * New interface gpgme_cancel() that can be used to cancel
   asynchronous operations.

Noteworthy changes in version 0.4.4 (2004-01-12)
------------------------------------------------

 * The member "class" in gpgme_key_sig_t and gpgme_new_signature_t has
   been renamed to "sig_class", to avoid clash with C++ compilers.  In
   the C API, the old name "class" has been preserved for backwards
   compatibility, but is deprecated.
