wiretap: Add a file_gets variant that returns a pointer to the NUL terminator
When using file_gets it's very difficult to determine how many characters
were read, because you can't distinguish between an embedded NUL and
a short line (note that the last line in a file may not have an LF at the
end). While it's still possible to do it via prefilling the buffer with
non-zero values, doing that is cumbersome, inefficient and error-prone.
This new function makes the task much easier.
The "p" in the name is meant to be reminiscent of the "p" in stpcpy.
