Anand J 814bb12a56 clean-up: removed duplicate #includes
Some files contain multiple #includes of the same header file.
Removed most of those unnecessary duplicate entries using
scripts/clean-includes.

Wei Jiangang bdc3f61dec accel: make configure_accelerator return void
Return the negated value of accel_initialised is meaningless,
and the caller vl doesn't check it.

Eduardo Habkost ac2da55e01 accel: Create accel object when initializing machine
Create an actual TYPE_ACCEL object when initializing a machine. This
will allow accelerator classes to implement some initialization on
instance_init, and to save state on the TYPE_ACCEL object.

Eduardo Habkost f6a1ef6440 accel: Pass MachineState object to accel init functions
Most of the machine options and machine state information is in the
MachineState object, not on the MachineClass. This will allow init
functions to use the MachineState object directly instead of
qemu_get_machine_opts() or the current_machine global.

Eduardo Habkost 0d15da8e6f accel: Rename 'init' method to 'init_machine'
Today, all accelerator init functions affect some global state:
* tcg_init() calls tcg_exec_init() and affects globals such as tcg_tcx,
  page size globals, and possibly others;
* kvm_init() changes the kvm_state global, cpu_interrupt_handler, and possibly
  others;
* xen_init() changes the xen_xc global, and registers a change state handler.

With the new accelerator QOM classes, initialization may now be split in two
steps:
* instance_init() will do basic initialization that doesn't affect any global
  state and don't need MachineState or MachineClass data. This will allow
  probing code to safely create multiple accelerator objects on the fly just
  for reporting host/accelerator capabilities, for example.
* accel_init_machine()/init_machine() will save the accelerator object in
  MachineState, and do initialization steps which still affect global state,
  machine state, or that need data from MachineClass or MachineState.

To clarify the difference between those two steps, rename init() to
init_machine().

Eduardo Habkost 3a6ce5147f accel: Move qtest accel registration to qtest.c
As qtest_availble() returns 1 only when CONFIG_POSIX is set, keep
setting AccelClass.available to keep current behavior (this is different
from what we did for KVM and Xen).

This also allows us to make qtest_init_accel() static.

Eduardo Habkost b152b05a35 accel: Move Xen registration code to xen-common.c
Note that this has an user-visible side-effect: instead of reporting
"Xen is not supported for this target", QEMU binaries not supporting Xen
will report "xen accelerator does not exist".

As xen_available() always return 1 when CONFIG_XEN is enabled, we don't
need to set AccelClass.available anymore. xen_enabled() is not being
removed yet, but only because vl.c is still using it.

This also allows us to make xen_init() static.

"KVM is not supported for this target", QEMU binaries not supporting KVM

As kvm_availble() always return 1 when CONFIG_KVM is enabled, we don't

completely removed yet only because qmp_query_kvm() still uses it.

This also allows us to make kvm_init() static.

Eduardo Habkost b31f9acaaa accel: Report unknown accelerator as "not found" instead of "does not exist"
As the accelerator classes won't be registered anymore if they are not
enabled at compile time, saying "does not exist" may be misleading, as
the accelerator may be simply disabled. Change the wording to just say
"not found".

When we move accel classes outside accel.c, the available() function
won't be necessary anymore, because the classes will be registered only
if the accelerator code is really enabled at build time.
