REORG: include: move stick_table.h to haproxy/stick_table{,-t}.h

The stktable_types[] array declaration was moved to the main file as
it had nothing to do in the types. A few declarations were reordered
in the types file so that defines were before the structs. Thread-t
was added since there are a few __decl_thread(). The loss of peers.h
revealed that cfgparse-listen needed it.
