libxl,xl: add max_event_channels option to xl configuration file
Add the 'max_event_channels' option to the xl configuration file to
limit the number of event channels that domain may use.
Plumb this option through to libxl via a new libxl_build_info field
and call xc_domain_set_max_evtchn() in the post build stage of domain
creation.
A new LIBXL_HAVE_BUILDINFO_EVENT_CHANNELS #define indicates that this
new field is available.
The default value of 1023 limits the domain to using the minimum
amount of global mapping pages and at most 5 xenheap pages.
