Attempt to make all the various string *strip methods the same.

 * Doc - add doc for when functions were added
 * UserString
 * string object methods
 * string module functions
'chars' is used for the last parameter everywhere.

These changes will be backported, since part of the changes
have already been made, but they were inconsistent.
