[Xen-devel] [PATCH v2 00/35] libxl refactoring to use ev_qmp (with API changes)

Patches with missing ackes:
    libxl: Use ev_qmp for switch_qemu_xen_logdirty
    libxl: Use ev_qmp in libxl_set_vcpuonline
    libxl_pci: Extract common part of *qemu_trad_watch_state_cb

The series depends on "Some cleanup of libxl" series.

On the quest to have QEMU depriviledge, we need to make quite a few changes to
libxl. This patch series rework quite a few libxl feature to use libxl__ev_qmp,
which is the new asynchronous way of communicating with QEMU in libxl.

Unfortunately, some libxl functions (in the public API) are supposed to be
synchronous but are communicating with QEMU before returning. So those functions
are made asynchronous with an additional parameter `libxl_asyncop_how'.

% libxl API changes

Functions that are changes:
    - libxl_domain_unpause
    - libxl_domain_pause
    - libxl_send_trigger
    - libxl_set_vcpuonline
    - libxl_retrieve_domain_configuration
    - libxl_qemu_monitor_command
