xc_domain_getinfolist() internally relies on a sysctl that performs
a linear search for the domids. Many callers of xc_domain_getinfolist()
who require information about a precise domid are much better off calling
xc_domain_getinfo_single() instead, that will use the getdomaininfo domctl
instead and ensure the returned domid matches the requested one. The domtctl
will find the domid faster too, because that uses hashed lists.

In do_domain_soft_reset(), a `libxl__domain_suspend_state' is used
without been properly initialised and disposed of. This lead do a
abort() in libxl due to the `dsps.qmp' state been used before been
initialised:
libxl__ev_qmp_send: Assertion `ev->state == qmp_state_disconnected || ev->state == qmp_state_connected' failed.
Once initialised, `dsps' also needs to be disposed of as the `qmp'
state might still be in the `Connected' state in the callback for
libxl__domain_suspend_device_model(). So this patch adds
libxl__domain_suspend_dispose() which can be called from the two
places where we need to dispose of `dsps'.

libxl_domain_resume() won't work correctly for the case it was called
due to a "xl save -c" command, i.e. to continue the suspended domain.
The information to do that is not saved in libxl__dm_resume_state for
non-HVM domains.

Carve out all libxenlight related sources and move them to
tools/libs/light in order to use the generic library build environment.
The closely related sources for libxl-save-helper and the libxl test
environment are being moved, too.
