Increase oldmalloc_increase with malloc_increase
instead of using obj_memsize_of().
This change will avoid the danger of memory full without major GC.

oldmalloc_increase_limit at Init_heap.
rb_objspace_alloc() is not called on some platforms.

* gc.c (gc_start_internal): GC.start() now accepts two optional
keyword arguments. These can be used to disable full_mark (minor
mark only) or disable immediate_sweep (use lazy sweep). These new
options are useful for benchmarking GC behavior, or performing minor
GC out-of-band.
* test/ruby/test_gc.rb (class TestGc): tests for new options.

* include/ruby/intern.h: add rb_gc_stat() for access to GC.stat
variables from c-api
* gc.c (rb_gc_stat): new c-api method. accepts either VALUE hash like
GC.stat, or VALUE symbol key and returns size_t directly. the second
form is useful to avoid allocations, i.e. for usage inside
INTERNAL_EVENT_GC tracepoints.
* gc.c (gc_stat): add GC.stat(:key) to return single value instead of hash
* gc.c (gc_stat_internal): helper method to retrieve single or all stat values

return malloc_usable_size() if possible.
* gc.c (MALLOC_ALLOCATED_SIZE): add new setting macro to enable
GC.allocated_size.
If platform supports `malloc_usable_size()' (or similar one),
GC.allocated_size can be implemented with this function.
Default is 0.
* gc.c (vm_xmalloc, vm_xrealloc, vm_xfree): use vm_malloc_size()
to detect collect allocated size.
* gc.c (vm_malloc_increase): refactoring.

two new events: GC_END_MARK and GC_END_SWEEP
* gc.c (gc_after_sweep): emit GC_END_SWEEP after lazy sweep is done
* gc.c (gc_marks_body): emit GC_END_MARK at end of minor/major mark
* ext/-test-/tracepoint/tracepoint.c (struct tracepoint_track): tests
for new events.
* test/-ext-/tracepoint/test_tracepoint.rb (class TestTracepointObj):
ditto.
* NEWS: remove ObjectSpace.after_gc_*_hook. These are only a sample,
and will be removed before ruby 2.1.
* ext/objspace/gc_hook.c: remove ObjectSpace.after_gc_end_hook=

* gc.c (rb_gc_set_params): define as separate function.
RUBY_ALIAS_FUNCTION is for simple alias only, the third parameter
will be ignored on gcc.

* gc.c (ruby_gc_set_params): Accept safe_level argument so GC tuning
settings can be applied before rb_safe_level() is available.
* internal.h (rb_gc_set_params): ditto.
* ruby.c (process_options): Apply GC tuning early during boot process
so boot-time allocations can benefit. This also benefits any code
loaded in via `ruby -r`.
