[xmlsec] libxml2 --without-http ... and xmlsec

[Aleksey Sanin]

Sorry, your patch is incorrect. Some tests from the tests suite use
external resources thus require HTTP support. Currently, if LibXML
does not have http/ftp compiled in, the xmlsec fails with an error
that indicates a problem with IO. Your patch masks the problem
with dummy http/ftp callbacks which is wrong. Also the user might
have reasons to compile LibXML without HTTP/FTP support because
s/he wants to use her/his own callbacks. In this case, your dummy
callbacks will make it harder.
