RW locking: Add a pair of re-entrant functions for readers
In some cases, the same lock_start_read() function could be reached
multiple times in a nested fashion, e.g. after running a callback which
returns the control flow to the same module through an API call done by
the module which installed the callback.

clusterer: Fix occasional deadlock during dlg/ul sync ops
This patch fixes a possible deadlock when running the MI
`dlg_cluster_sync` or `ul_cluster_sync` functions, due to re-entrant
lock_start_read(). Deadlock example:
usleep()
clusterer_bcast_msg()
cl_send_all() <--------------- 3. lock_start_read()
^^^ clusterer (cannot re-acquire same lock due to writer...)
dlg_replicate_profiles()
repl_prof_remove()
destroy_linker()
remove_dlg_prof_table()
rcv_cluster_event()
^^^ dialog
handle_sync_end()
handle_sync_packet()
bin_rcv_cl_extra_packets() <--------------- 1. lock_start_read()
^^^ clusterer
usleep()
bin_rcv_cl_packets() <--------------- 2. lock_start_write()
