[Serdev] xlog color patch

[Evan Borgström]

	You might want to increase COL_BUF or move it to allocating memory as 
needed, 20 bytes doesn't seem large enough IMHO as 3 color entities 
(with fore & background colors) in a xlog call would overflow the 
variable (5 + (5*3) + 1 = 21). How does the xlog module with this patch 
react to something like:

   xlog("L_ERR", 
"%Csrtesting%Cybtesting%Cwstesting%Cswtesting%Cgrtesting%Crgtesting\n");

	It's not likely to come up but you never know...
