  Log:
    * 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__.
