* gc.c (objspace_malloc_prepare): remove size check because it is
used by objspace_xmalloc and objspace_xcalloc.
objspace_xmalloc introduces its own check in this commit.
objspace_xcalloc checks with xmalloc2_size (ruby_xmalloc2_size).
* gc.c (objspace_xmalloc0): common xmalloc function.
* gc.c (objspace_xmalloc): introduce its own size check.
* gc.c (objspace_xmalloc2): separated from ruby_xmalloc2 to clarify
the layer who has the responsibility to check the size.
* gc.c (objspace_xrealloc): remove duplicated size check.
* gc.c (ruby_xmalloc2): use objspace_xmalloc2.
* include/ruby/ruby.h (ruby_xmalloc2_size): follow the size limit
as SSIZE_MAX. Note that ISO C says size_t is unsigned integer.
