    Introduce the cairo-missing library

    The cairo-missing library provides the functions which are needed in
    order to correctly compile cairo (or its utilities) and which were
    not found during configuration.

    Fixes the build on MacOS X Lion, which failed because of collisons
    between the cairo internal getline and strndup and those in libc:

    cairo-analyse-trace.c:282: error: static declaration of ‘getline’
    follows non-stati$ /usr/include/stdio.h:449: error: previous
    declaration of ‘getline’ was here cairo-analyse-trace.c:307: error:
    static declaration of ‘strndup’ follows non-stati$ ...

So, appears to be for providing system functions that are missing on
certain platforms.
