Changelog:
Changes with APR-util 1.6.1

  *) Win32: Add function exports from new apr_crypto API's missing in 1.6.0.

  *) Win32: Introduce XML_PARSER build-time variable to select the expat
     library name to be linked to libaprutil-1.dll. See Makefile.win

  *) Win32: Removed lingering xml/xml.dsp project forked from the expat
     Project in the 1.9x era. Use expat's maintained build schema instead,
     prior to building apr-util.
