Revert "Atom length comment and datatype fixes"

This reverts commit 7d4c56a10a3dcc201c78521d208f2150d3ea57df.

local.c: In function ‘httpSpecialRequest’:

local.c:235:22: warning: format ‘%d’ expects argument of type ‘int’, \
but argument 12 has type ‘long unsigned int’ [-Wformat]

but argument 13 has type ‘long unsigned int’ [-Wformat]
