Eliminate simple uses of snprintf

[GoogleCodeExporter]

The VM makes calls to snprintf() in some places to format integers as strings.  
Some of these are very simple cases that can be replaced with a simpler 
function like ltoa()... which could be manually coded in the VM.

The goal is to reduce external dependencies.

snprintf() is used in float.c, int.c, strobj.c and heap.c.  There are only 2 
places where snprintf() is not easily replaced: formatting floats and 
python-string formatting (where string format args can be complex).

- Removed use in heap.c in favor of direct character manipulation.
- Removed uses in int.c and obj.c and used the new sli_ltoa10() function 
instead.
- Created sli_ltoa10() and sli_puts() in sli.c
