Subject: [PATCH] Never leave behind .repodata lock on exit (RhBug:1906831
createrepo_c was removing `.repodata` if `exit_val` was se to failure.
Problem is `exit_val` is set only on a couple of places so most of the
failures (no matter how rare) leave `.repodata` behind.
However because on a successful run `.repodata` is renamed to normal
output `repodata` we know that if `.repodata` are present there was an
error and we can delete them.

Subject: [PATCH 2/2] Parse xml snippet in smaller parts (RhBug:1859689)
If string passed to xmlParseChunk (function froml ibxml2) is too
big the function errors out, its safer to parse the snippet in
smaller parts.
