From: Michael Tokarev <m...@tls.msk.ru>
For a long time, we assumed that libxml2 is necessary for parallels
block format support (block/parallels*). However, this format actually
does not use libxml [*]. Since this is the only user of libxml2 in
whole QEMU tree, we can drop all libxml2 checks and dependencies too.
It is even more: --enable-parallels configure option was the only
option which was silently ignored when it's (fake) dependency
(libxml2) isn't installed.
Drop all mentions of libxml2.
[*] Actually the basis for libxml use were introduced in commit
ed279a06c53 ("configure: add dependency") but the implementation
was never merged:
