Update all index entries to match the working directory
This method will fail in bare index instances.
This scans the existing index entries and synchronizes them with the
working directory, deleting them if the corresponding working directory
file no longer exists otherwise updating the information (including
adding the latest version of file to the ODB if needed).
If you provide a callback function, it will be invoked on each matching
item in the index immediately *before* it is updated (either refreshed
or removed depending on working directory state). Return 0 to proceed
with updating the item, > 0 to skip the item, and < 0 to abort the scan.
@param index An existing index object
@param pathspec array of path patterns
@param callback notification callback for each updated path (also
gets index of matching pathspec entry); can be null;
return 0 to add, >0 to skip, <0 to abort scan.
@param payload payload passed through to callback function
@return 0 on success, negative callback return value, or error code
