* Take string of arguments and return file flags. This
* version works a little differently than strtofflags(3).
* In particular, it always tests every token, skipping any
* unrecognized tokens. It returns a pointer to the first
* unrecognized token, or NULL if every token was recognized.
* This version is also const-correct and does not modify the
* provided string.
