[PATCH v1 1/2] StdLib/sys/termios: Define cc_t as unsigned

[Alex James <theracermaster@gmail.com>]

According to the POSIX standard, cc_t, speed_t, and tcflag_t should be
unsigned integer types. Define cc_t as unsigned to match POSIX and fix
an implicit conversion error when building StdLib with XCODE5/CLANG38.
