doc about vasprintf-posix module

[Bruno Haible]

The doc does not mention the advantages of the 'vasprintf-posix' module,
compared to the 'vasprintf' module. This fixes it.


2010-12-19  Bruno Haible  <address@hidden>

        doc: Mention vasprintf-posix module.
        * doc/glibc-functions/asprintf.texi: Mention the workarounds present in
        the 'vasprintf-posix' module.
        * doc/glibc-functions/vasprintf.texi: Likewise.
