warning cleanup: unsigned < 0 comparisons.

This is the fourth round of an effort to enable GCC's -Wextra
option. Instances of code that test whether an unsigned
quantity is negative are repaired. Real bugs are found.

* itypes.c (c_u32, c_uint, c_ulong): Remove useless comparison
for < 0 that was copy-pasted from the signed cases.

* linenoise/linenoise.c (show_help, edit): Do not test the
return value of the getch_fn callback for negative. It returns
wint_t, which may be unsigned. Test for the WEOF value.
This is a bug because since the original comparison is
always false, the code fails to catch the WEOF return.
