Update to 1.5.1:

Noteworthy changes in version 1.5.1 (2014-07-30) [C24/A13/R0]
-------------------------------------------------------------

 * Fixed possible overflow in gpgsm and uiserver engines.
   [CVE-2014-3564]

 * Interface changes relative to the 1.5.0 release:
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 GPGME_KEYLIST_MODE_WITH_SECRET NEW.

Noteworthy changes in version 1.5.0 (2014-05-21) [C23/A12/R0]
-------------------------------------------------------------

 * On Unices the engine file names are not not anymore hardwired but
   located via the envvar PATH.  All options to set the name of the
   engines for the configure run are removed.

 * If GPGME finds the gpgconf binary it defaults to using gpg2 or
   whatever gpgconf tells as name for the OpenPGP engine.  If gpgconf
   is not found, GPGME looks for an engine named "gpg".

 * New feature to use the gpgme I/O subsystem to run arbitrary
   commands.

 * New flag to use encryption without the default compression step.

 * New function to access "gpg-conf --list-dirs"

 * New configure option --enable-fixed-path for use by Android.

 * Support ECC algorithms.

 * Interface changes relative to the 1.4.3 release:
