dlmalloc version isn't current on eLua

[King, Mike]

Just in case the developers are not aware, the version of dlmalloc that's used by eLua is not current.  Will eLua uses the newer version?  I don't know if it will offer any benefit to eLua.

We actually have two dlmalloc versions on eLua:

1. the one in Newlib (don't know which one it is, as it depends on the Newlib version). This is the default, and we keep it the default because it is smaller than 2 below.
2. another one in src/dlmalloc.c, which is more recent than what I've found in the different Newlibs eLua uses (don't know if it's the latest one though) and it is used by default on boards with multiple RAM zones (for example on-chip RAM + external RAM). It can be forced with "allocator=multiple" in the scons command line.

I'll check if 2 above is the latest dlmalloc version, thanks for letting us know about this. I doubt it would make any significant difference, but one never knows for sure until one tries :)

Best,
Bogdan
