* configure.ac <adns>: Use adns_free as probe function for libadns.
(HAVE_ADNS_FREE): Remove bogus tests to set this and remove the macro.
(ADNSLIBS): Do not ac_subst - it is only used within configure.
--
adns_free is required on Windows anyway (for robustness reasons) and
it has been around for so long now that we do not need a separate
test. An upstream adns 1.5 has meanwhile been release but I doubt that
this has the required Windows code - and it is not libtool based
anyway.
* common/dns-cert.c: Remove iobuf.h.
(get_dns_cert): Rename to _get_dns_cert. Remove MAX_SIZE arg. Change
iobuf arg to a estream-t. Rewrite function to make use of estream
instead of iobuf. Require all parameters. Return an gpg_error_t
error instead of the type. Add arg ERRSOURCE.
* common/dns-cert.h (get_dns_cert): New macro to pass the error source
to _gpg_dns_cert.
* common/t-dns-cert.c (main): Adjust for changes in get_dns_cert.
* g10/keyserver.c (keyserver_import_cert): Ditto.
* doc/gpg.texi (GPG Configuration Options): Remove max-cert-size.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
