[PATCH v2 0/9] Enable Xenstore-stubdom Live Update

[Juergen Gross <jgross@xxxxxxxx>]

With this series applied I was able to perform Live Update of Xenstore
running in a PVH stubdom.

One relevant change in this series is how the Xenstore state is being
read after activating the new binary. Instead of using mmap() the
state records are read one by one via fread(). This might have a
small performance impact for the daemon live update case, but it
should be neglectable.

Changes in V2:
- rebase
- former patches 1 and 2 have been committed already
- former patch 5 moved to start of the series (has all needed Acks)
- new patches 8 and 9

Juergen Gross (9):
  xenstored: use fread() instead of mmap() for reading live update state
  libevtchn: add O_CLOEXEC support for Mini-OS
  libxengnttab: set the cloexec flag on Mini-OS
  xenstored: don't use xenevtchn_fdopen() in stubdom
  tools/libxenevtchn: add xenevtchn_bind() under Mini-OS
  xenstored: rebind event channels after live update in stubdom
  tools/xenstored: make stubdom_init() live update aware
  SUPPORT.md: add xenstorepvh-stubdom live update
  CHANGELOG.md: add xenstorepvh-stubdom live update
