libxtables: xt_xlate_add() to take care of spacing
Try to eliminate most of the whitespace issues by separating strings
from separate xt_xlate_add() calls by whitespace if needed.
Cover the common case of consecutive range, list or MAC/IP address
printing by inserting whitespace only if the string to be appended
starts with an alphanumeric character or a brace. The latter helps to
make spacing in anonymous sets consistent.
Provide *_nospc() variants which disable the auto-spacing for the
mandatory exception to the rule.
Make things round by dropping any trailing whitespace before returning
the buffer via xt_xlate_get().
