This change anticipates scenarios where `max_altp2m` is set to its maximum
supported value (i.e., 512), ensuring sufficient memory is allocated upfront
to accommodate all altp2m tables without initialization failure.

This series introduces the ability to configure the maximum number of altp2m
tables during domain creation. Previously, the limits were hardcoded to a
maximum of 10. This change allows for greater flexibility in environments that
require more or fewer altp2m views.

From: Petr Beneš
This patch addresses an issue where the fast singlestep setting would persist
despite xc_domain_debug_control being called with
XEN_DOMCTL_DEBUG_OP_SINGLE_STEP_OFF.
Specifically, if fast singlestep was enabled in a VMI session and that session
stopped before the MTF trap

Add the missing `vmtrace_buf_kb` field to the OCaml bindings to match the
vm.cfg configuration, correcting an oversight from its initial introduction.

From: Petr Beneš
This patch addresses a behavior discrepancy in the handling of altp2m views,
where upon the creation and subsequent EPT violation, the page access
permissions were incorrectly inherited from the hostp2m instead of respecting
the altp2m default_access.
