These are general backport requests, not specifically for 4.13

d92ba1aa7cf8 - tools/ocaml: libxb: Harden stub_header_of_string()
59b087e39544 - tools/ocaml: Fix stubs build when OCaml has been compiled
with -safe-string
78686437e949 - tools/ocaml: libxb: Avoid to use String_val() when value
is bytes
2b8079610ec5 - tools/libxc: misc: Mark const the parameter 'keys' of
xc_send_debug_keys()
a6ed77f1e033 - oxenstored: fix ABI breakage introduced in Xen 4.9.0

The penultimate one is an API change, but strictly in a relaxing
direction.  The final one is an ABI change, but fixing a regression.


5e31789634 - tools/ocaml/libs/xb: Do not crash after xenbus is unmapped
2a47797d1f - tools/oxenstored: Trim txhistory on xenbus reconnect
c8b9670825 - tools/oxenstored: Fix quota calculation for mkdir EEXIST
dc8caf214fb - tools/oxenstored: Reject invalid watch paths early
45dee7d92b - tools/oxenstored: mkdir conflicts were sometimes missed


Do we want to backport the -Og fixes so we can get ABI checking working?
