Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.

These casts should not be needed on 32-bit hosts, either.
* keyboard.c (read_char):
* lread.c (Fload): Remove casts to unsigned.

Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
These casts should not be needed on 32-bit hosts, either.
* keyboard.c (read_char):
* lread.c (Fload): Remove casts to unsigned.
* lisp.h (UNSIGNED_CMP): New macro.
This fixes comparison bugs on 64-bit hosts.
(ASCII_CHAR_P): Use it.
