[xslt] Work report/code review part 1

[Keith Isdale <k_isdale tpg com au>]

This is the first part in series of xslt@gnome posts that explains what
I've been doing.  Please post reguarding this message to the xslt@gnome mail 
list.

This part presents a summary of requested changes to libxml in
the order that they occur in libxml2-2.4.3_ki.diff. And has been created so
the the changes I recommend can be reviewed. Most of the changes are to
allow the reuse of code within debugXML.c. The attached file
libxml2-2.4.3_ki.diff is much smaller than version on sourceforge and as I
have removed all "noise" diff text about rebuildable files.
