Modified files:
lib/libc/stdlib malloc.c
Log:
Maintain two trees instead of one (old_chunks --> old_chunks_{ad,szad}) in
order to support re-use of multi-chunk unused regions within the DSS for
huge allocations. This generalization is important to correct function
when mmap-based allocation is disabled.
Avoid zeroing re-used memory in the DSS unless it really needs to be
zeroed.
