If we have root privileges, die with an error. (Eg, for security reasons.) Param argv0 should be argv[0] or similar; fallback is used instead if argv0 is NULL. But don't die on systems where the user is always root... (a general test for this would be better). Doesn't use log_*() because gets called before logging is setup.

Search for filenames with the "infix" substring in the "subpath" subdirectory of the data path. "nodups" removes duplicate names.

| const char * fileinfoname | ( | const struct strvec * | dirs, |

Returns a filename to access the specified file from a directory by searching all specified directories for the file.
If the specified 'filename' is NULL, the returned string contains the effective path. (But this should probably only be used for debug output.)
Returns NULL if the specified filename cannot be found in any of the data directories. (A file is considered "found" if it can be read-opened.) The returned pointer points to static memory, so this function can only supply one filename at a time. Don't free that pointer.

Given n names, with maximum length max_len_name, accessed by accessor_fn(0) to accessor_fn(n-1), look for matching prefix according to given comparison function. Returns type of match or fail, and for return <= M_PRE_AMBIGUOUS sets *ind_result with matching index (or for ambiguous, first match). If max_len_name == 0, treat as no maximum. If the int array 'matches' is non-NULL, up to 'max_matches' ambiguous matching names indices will be inserted into it. If 'pnum_matches' is non-NULL, it will be set to the number of indices inserted into 'matches'.

| char scanin | ( | const char ** | buf, |
| char * | delimiters, | ||
| char * | dest, | ||
| int | size | ||
| ) |
Scan in a word or set of words from start to but not including any of the given delimiters. The buf pointer will point past delimiter, or be set to NULL if there is nothing there. Removes excess white space.
This function should be safe, and dest will contain "\0" and buf == NULL on failure. We always fail gently.
Due to the way the scanning is performed, looking for a space will give you the first word even if it comes before multiple spaces.
Returns delimiter found.
Pass in NULL for dest and -1 for size to just skip ahead. Note that if nothing is found, dest will contain the whole string, minus leading and trailing whitespace. You can scan for "" to conveniently grab the remainder of a string.
