Pull up following revision(s) (requested by enami in ticket #1327):
lib/libc/stdlib/jemalloc.c: revision 1.21
Fix race condition on reallocation of huge category.
We need to remove the old region before mremap() since if it relesae the
old region, other thread may map it for the same huge category allocation
and insert it to the tree before we acquire a lock after mremap().
