core: Allow setting import filters when importing keys

* src/context.h (struct gpgme_context): New field import_filter.
* src/engine-backend.h (struct engine_ops): Add arg import_filter to
field 'import'.
* src/engine-gpg.c (gpg_import): Add arg import_filter and pass option
--import-filter with argument value to gpg. Adjust all callers.
* src/engine-gpgsm.c (gpgsm_import): Add dummy arg import_filter.
* src/gpgme.c (gpgme_release): Free 'import_filter'.
(gpgme_set_ctx_flag, gpgme_get_ctx_flag): New flag "import-filter".

* tests/run-import.c (main): Add option --import-filter.
--

This makes the --import-filter option available in the GPGME API for
key imports.
