Can you rename xmlNop to something like xmlInputNopReadCallback and remove the 
now unnecessary casts when it is used? Also annotate the unused parameters 
with ATTRIBUTE_UNUSED.

strdup is a POSIX extension and can't be used for platform compatibility 
reasons. You'll probably have to write a wrapper around xmlStrdup.

If possible, please format patches with git-format-patch.
