Allow alternate "low-level" emit function from xdl_diff
For some users (e.g. git blame), getting textual patch output is just
extra work, as they can get all the information they need from the low-
level diff structures. Allow for an alternate low-level emit function
to be defined to allow bypassing the textual patch generation; set
xemitconf_t's emit_func member to enable this.
The (void (*)()) type is pretty ugly, but the alternative would be to
include most of the private xdiff headers in xdiff.h to get the types
required for the "proper" function prototype. Also, a (void *) won't
work, as ANSI C doesn't allow a function pointer to be cast to an
object pointer.
