[xml] xml2-config.bat for windows

[Simon Doodkin <helpmepro1 gmail com>]

i have wanted to link against the libxml2.dll lib but the building script reported an error xml2-config was missing.

i could get libxml from here 

http://sourceforge.net/projects/gnuwin32/files/libxml/2.4.12-1/

and a newer version from here ftp://ftp.zlatkovic.com/libxml/
but  xml2-config required shell script on windows 

so i rewrote xml2-config to xml2-config.bat

not sure how it fits current build 

it seems like paths in file ware dynamically genetically

but  i have made the prefix path to be calculated to the directory of  xml2-config.bat
