Fix out-of-memory condition in conf
conf has the ability to expand variables in config files. Repeatedly doing
this can lead to an exponential increase in the amount of memory required.
This places a limit on the length of a value that can result from an
expansion.
Credit to OSS-Fuzz for finding this problem.
