* ext/objspace/objspace.c: support ObjectSpace.trace_object_allocations.
Read the following test to know HOWTO. This feature is a sample of RUBY_INTERNAL_EVENT. * test/objspace/test_objspace.rb: add a test. * ext/objspace/object_tracing.c: ditto. * gc.c (rb_gc_count): add. THis function returns GC count. * internal.h: add decl. of rb_gc_count(). Same as `GC.count'. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40957 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
