* libexslt/.cvsignore: some more generated files to ignore
        * libexslt/Makefile.am: utils.h not installed anymore
        * libexslt/common.c libexslt/exslt.[ch] libexslt/functions.c
          libexslt/math.c libexslt/sets.c:
          changed function prefix from exsl* to exslt*
          {common.c,exslt.c} moved exsltLib{rary,exslt,xslt,xml}Version
          from common.c to exslt.c
          {common.c} removed exslNodeSetFunction, uses xsltFunctionNodeSet
          instead
        * libxslt/extra.c: fixed xsltFunctionNodeSet to accept
          XPATH_NODESET arguments in addition to XPATH_XSLT_TREE
        * xsltproc/xsltproc.c: updated to use the new function prefix
