Description of problem:

There is no library for altering service states, checking service states, etc.  This is required in order for other management interfaces to interface with rgmanager directly instead of having to use clustat/clusvcadm.

Modelling should follow the cman API; maybe something like:

rgm_handle_t h = rgm_init();

int rgm_get_service_count(rgm_handle_t h);

typedef struct rgm_service_state_t;

int ret = rgm_get_service_states(rgm_handle_t h, rgm_service_state_t *states, int nstates);

int event = rgm_poll(rgm_handle_t h, struct timeval *timeout);

#define RGM_DISPATCH_ONE 0x1
#define RGM_DISPATCH_ALL 0x2
#define RGM_DISPATCH_BLOCKING 0x4

int rgm_dispatch(rgm_handle_t h, int flags, rgm_callback_t callback_func);
