the malloc/free level, not within the heap abstraction, and there's a
separate lock to control sbrk access.
Also, get rid of the separate `unmap_free_area' function in free.c, and
just put the code in the `free' function directly, which saves a bunch
of space (even compared to using an inline function) for some reason.

* Instead of using mmap/munmap directly for large allocations, just use
the heap for everything (this is reasonable now that heap memory can
be unmapped).
* Use sbrk instead of mmap/munmap on systems with an MMU.

smarter than the old "malloc-simple", and actually works, unlike
the old "malloc". So kill the old "malloc-simple" and the old
"malloc" and replace them with Miles' new malloc implementation.
Update Config files to match. Thanks Miles!

defining things to "0" in the disabled case to outright undefining them, lest
code that does an "#ifdef FOO" get inadvertantly triggered. Remove now
unneeded lines from Rules.mak which makes the command line smaller and avoids
redundancy (since this stuff is now pulled in via features.h).

Also fixes 2 very important malloc bugs! Anyone using malloc (esp mmu-less)
should update and recompile.

using functions instead on Inlining (size vas speed tradeoff). I ran the
results through indent. Looking pretty good IMHO.

support), and other updates by me (better cross platform, cross-compiler,
etc, support. Now compiles with 2.0.x kernels for armnommu.
