[Xcb] New aux function

[Barton C Massey]

The problem with this, as we've talked about before, is that
some strings returned by the server may already have
embedded nulls, in which case all the C functions will do
the wrong thing.

What is needed, I fear, is an aux library for dealing with
X-style counted strings, with the standard stuff in it (from
strings.h and stdio.h, for starters).

Alternatively, your conversion function could transform
embedded nulls in the string into something else.  Maybe the
converter should translate to UTF, and use the null in the
Unicode reserved area as a representation of embedded null
bytes?
