global: Use check-local in Makefile.am instead of overriding check directly This helps with dependency problems, like running "make check" in lib-storage without "make" first would try to compile the test programs too early and fail.

lib-sql, lib-ldap: Fix link dependencies Fixes using the gold linker.

Fixed linking with OSX.

lib-ldap: Reverted previous commit for now. We don't have libdovecot built at at this stage. But we can't build it earlier, because it needs lib-dict-extra, which needs lib-ldap. So we have cyclical dependencies now.

lib-ldap: Add libdovecot dependency to libdovecot-ldap Required for linking to work on OSX.

lib-ldap: Added initial connection pooling code. This is mainly about allowing multiple dict-ldaps to use the same ldap-connection. In future we could support load balancing with multiple concurrent LDAP connections.

lib-ldap: Add lib-ldap implementation
