compatibility: replace iscntrl with own ISCNTRL macro
It is unspecified if the C locale iscntrl is compatible with ASCII or not.
Noticed when testing on OpenBSD 3.8 which uses extended ASCII and also uses the
C1 range for control-characters. This breaks support with UTF-8.
Reference:
https://en.wikipedia.org/wiki/C0_and_C1_control_codes#C1_control_codes_for_general_use
C1 table.
Force an own definition of an ASCII-compatible control-character range since
sfeed expects input to be UTF-8 (or converted from iconv) and so output to be
UTF-8 aswell.
