/* Derived from GNU libc's getline.
The behavior is almost the same as getline. See man getline.
The differences are
(1) using file descriptor instead of FILE *,
(2) the order of arguments; the file descriptor comes the first, and
(3) the addition of third argument, UNBUFFERED_READ; this argument
(1) using file descriptor instead of FILE *;
(2) the order of arguments: the file descriptor comes first;
(3) the addition of a fourth argument, DELIM; sets the delimiter to
be something other than newline if desired. If setting DELIM,
the next argument should be 1; and
(4) the addition of a fifth argument, UNBUFFERED_READ; this argument
controls whether get_line uses buffering or not to get a byte data
from FD. get_line uses zreadc if UNBUFFERED_READ is zero; and
uses zread if UNBUFFERED_READ is non-zero.
