unused functions in dbus-string.c

[Roberto -MadBob- Guido]

Looking at dbus-string.c I see a number of functions unused in the rest of the 
code, isolated by the DBUS_BUILD_TESTS preprocessor condition and sometime 
checked in unit tests.

Those are:
_dbus_string_steal_data_len
_dbus_string_copy_data_len
_dbus_string_append_unichar
_dbus_string_append_4_aligned
_dbus_string_append_8_aligned
_dbus_string_get_unichar

Is there any reason to maintain that code? Perhaps those were used in past, 
but not erased waiting for recycling?
