libxc: add wrappers for XENMEM {increase,decrease}_reservation and
populate_physmap
Currently the wrappers for these hypercalls swallow partial success
and return failure to the caller.
In order to use these functions more widely instead of open-coding
uses of XENMEM_* and xc_memory_op add variants which return the actual
hypercall result.
Therefore add the following functions:
xc_domain_increase_reservation
xc_domain_decrease_reservation
xc_domain_populate_physmap
and implement the existing semantics using these new functions as
xc_domain_increase_reservation_exact
xc_domain_decrease_reservation_exact
xc_domain_populate_physmap_exact
replacing the existing xc_domain_memory_* functions.
Use these new functions to replace all open coded uses of
XENMEM_increase_reservation, XENMEM_decrease_reservation and
XENMEM_populate_physmap.
Also rename xc_domain_memory_*_pod_target to xc_domain_*_pod_target
for consistency.
Temporarily add a compatibility macro for
xc_domain_memory_populate_physmap to allow time for qemu to catch up.
