* ext/coverage/coverage.c, ext/coverage/extconf.rb: eliminate

  COVERAGE__ and introduce coverage.so instead.  How to measure
  coverage: (1) require "coverage.so", (2) require or load Ruby source
  file, and (3) Coverage.result will return the same hash as COVERAGE__.
  [ruby-dev:35324]

* thread.c (rb_enable_coverages): start coverage measurement by using
  rb_add_event_hook.

* thread.c (rb_get_coverages): returns current results of coverage
  measurement.

* include/ruby/intern.h: add prototype for above two functions.

* vm_core.h, vm.c: add field of coverages to rb_vm_t.

* insns.def (trace): remove special handling for COVERAGE__.

* iseq.c (prepare_iseq_build): switch COVERAGE__ to
  rb_get_coverages().

* parse.y (coverage): ditto.

* thread.c (clear_coverage): ditto.

* lib/coverage.rb: use coverage.so instead of COVERAGE__.
