This function is used to encode a name/value pair. This should be
used on any field being logged that potentially contains a space, a
double-quote, or a control character. Any value containing those have
to be specially encoded for the auparse library to correctly handle
the value. The encoding method is designed to prevent log injection
attacks where malicious values could cause parsing errors.
To use this function, pass the name string and value strings on their
respective arguments. If the value is likely to have a NUL value
embedded within it, you will need to pass a value length that tells
in bytes how big the value is. Otherwise, you can pass a 0 for vlen
and the function will simply use strlen against the value pointer.
Also be aware that the name of the field will cause auparse to do
certain things when interpretting the value. If the name is uid, a
user id value in decimal is expected. Make sure that well known names
are used for their intended purpose or that there is no chance of
name collision with something new.
