[En-Nut-Discussion] NutHeapRealloc

[Thiago A. Corrêa]

Well, I plan on using it *smile*

It seams pro/wins.c could free some of it's memory after encoding the
string. True it's a minor piece, but there are probably others. Netbuf
comes to mind.

I'm attaching a patch with Moritz changes plus a few of my own for
further review. This also adds realloc to the crt, so user code can
use it more easily.

This still doesn't enable the shared memory or the per thread memory
allocation (requires some changes to the config to enable defines).
