"RUBY_GC_HEAP_OLDOBJECT_LIMIT_FACTOR" to control major/minor GC
frequency.
Do full GC when the number of old objects is more than R * N
where R is this factor and
N is the number of old objects just after last full GC.
* test/ruby/test_gc.rb: add a test.

This function *ONLY* works just after marking phase,
before any sweeping.
This function is highly depending current GC implementation
and can be removed future version.

integer environment parameters for sizes.

(changed by last commit) because "" or "foo" (not a number) strings
are parsed as 0. They should be rejected.
* gc.c (get_envparam_double): ditto.

then set objspace->rgengc.oldmalloc_increase_limit.
Without this fix, the env variable RUBY_GC_OLDMALLOC_LIMIT
does not work.
* gc.c (get_envparam_int): accept a value equals to lowerbounds.
* gc.c (get_envparam_double): ditto.

so that a debugger can show its content at once.

heap_get_freepage(). It returns freeobj instead of freepage.
This is not on hot path.

is set after the while() loop already.
