• ops.h (_gpgme_key_append_name): Same in prototype.
• key.c (_gpgme_key_append_name): Make SRC argument pointer to

const char.

• posix-util.c (_gpgme_get_uiserver_socket_path): Make HOMEDIR

const.

• vfs-mount.c (gpgme_op_vfs_transact_start): Never define this

potentially useful but currently unused function.
