libio: Implement internal function __libc_readline_unlocked
This is a variant of fgets which fails with ERANGE if the buffer is too small, and the buffer length is given as an argument of type size_t. This function will be useful for implementing NSS file reading operations. Compared to a direct implementation using the public API, it avoids an lseek system call in case the line terminator can be found in the internal read buffer.
