We have over 50 uses of "isatty(1)" and "isatty(2)" in the codebase,
and around 10 "isatty(0)", but three callers used the
{STDIN_FILENO,STD{OUT,ERR}_FILENO} macros in "stdlib.h" to refer to
them.
Let's change these for consistency. This makes it easier to change
all calls to isatty() at a whim, which is useful to test some
scenarios[1].
