dirmngr: Better encapsulate the keyservers variable.

Browse Source 
* dirmngr/dirmngr.h (struct server_control_s): Move field keyservers
from here...
* dirmngr/server.c (struct server_local_s): ... to here.  Update
users.
* dirmngr/ks-action.h (ks_action_resolve): Add argument keyservers.
(ks_action_search): Likewise.
(ks_action_get): Likewise.
(ks_action_put): Likewise.
* dirmngr/ks-action.c (ks_action_resolve): Add argument keyservers.
Use it instead of ctrl->keyservers.
(ks_action_search): Likewise.
(ks_action_get): Likewise.
(ks_action_put): Likewise.
