Enable infrared, remember to alter the #ifdef in sane.h
and use tiffscan svn to test.

tiffscan --device ... --scan --autofocus --ae-wb --depth=12 --infrared=yes
Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
Global replace of u_int??_t with C9x standard based uintxx_t
in order to remove some tricky and overlapping portability logic
from acinclude.m4 and leave it in only m4/stdint.m4.
