ram_save_queue_pages() has an 'err' label that can be replaced by
'return -1' instead.

Same thing with ram_discard_range(), and in this case we can also
get rid of the 'ret' variable and return either '-1' on error
or the result of ram_block_discard_range().

Commit 1bd71dce tries to prevent a finishmigrate -> prelaunch
transition by exiting at the beginning of the main_loop_should_exit()
function if the state is already finishmigrate.

As the finishmigrate state is set in the migration thread it can
happen concurrently to the function. The migration thread and the
function are normally protected by the iothread mutex and thus the
state should no evolve between the start of the function and its end.

Unfortunately during the function life the lock is released by
pause_all_vcpus() just before the point we need to be sure we are
not in finishmigrate state and if the migration thread is waiting
for the lock it will take the opportunity to change the state
to finishmigrate.

The only way to be sure we are not in the finishmigrate state when
we need is to check the state after the pause_all_vcpus() function.

The wfi instruction can be configured to be trapped by a higher exception
level, such as the EL2 hypervisor. When the instruction is trapped, the
program counter should contain the address of the wfi instruction that
caused the exception. The program counter is adjusted for this in the wfi op
helper function.

However, this correction is done to env->pc, which only applies to AArch64
mode. For AArch32, the program counter is stored in env->regs[15]. This
adds an if-else statement to modify the correct program counter location
based on the the current CPU mode.

According to the specification "Semihosting for AArch32 and Aarch64",
the SYS_OPEN operation should return:

 - A nonzero handle if the call is successful
 - -1 if the call is not successful

So, it should never return 0.

Prior to commit 35e9a0a8 ("target/arm/arm-semi: Make semihosting
code hand out its own file descriptors"), the guest fd matched to the
host fd. It returned a nonzero handle on success since the fd 0 is
already used for stdin.

Now that the guest fd is the index of guestfd_array, it starts from 0.

I noticed this issue particularly because Trusted Firmware-A built with
PLAT=qemu is no longer working. Its io_semihosting driver only handles
a positive return value as a valid filehandle.

Basically, there are two ways to fix this:

  - Use (guestfd - 1) as the index of guestfs_arrary. We need to insert
    increment/decrement to convert the guestfd and the array index back
    and forth.

  - Keep using guestfd as the index of guestfs_array. The first entry
    of guestfs_array is left unused.

I thought the latter is simpler. We end up with wasting a small piece
of memory for the unused first entry of guestfd_array, but this is
probably not a big deal.

The mask used when setting FPCSR allows setting bits 10 to 1.  However,
OpenRISC has flags and config bits in 11 to 1, 11 being Divide by Zero
Flag (DZF).  This seems like an off-by-one bug.

This was found when testing the GLIBC test suite which has test cases to
set and clear all bits.

Commit e51e711b has moved the initialization of start_address and
end_address after the definition of the command line argument,
where the nvramrc is initialized, and thus the loop is between 0 and 0
rather than 1 MiB and 100 MiB.

It doesn't affect the result of the test if all the tests are run in
sequence because the two first tests don't run the loop, so the
values are correctly initialized when we actually need them.

But it hangs when we ask to run only one test, for instance:

    QTEST_QEMU_BINARY=ppc64-softmmu/qemu-system-ppc64 \
    tests/migration-test -m=quick -p /ppc64/migration/validate_uuid_error

Since commit 1e8a1fae("test: Move qtests to a separate

this breaks the script used to rebuild the expected ACPI
tables for bios-tables-test. Update the script with correct
path.

Commit c4c00922 introduced the use of the GdkMonitor API, which
was introduced in GTK+ 3.22:
https://developer.gnome.org/gdk3/stable/api-index-3-22.html#api-index-3.22

Unfortunately this break building with older versions, as on Ubuntu
Xenial which provides GTK+ 3.18:

  $ lsb_release -cd
  Description:    Ubuntu 16.04.5 LTS
  Codename:       xenial

  $ ./configure && make
  GTK support       yes (3.18.9)
  GTK GL support    no

GTK+ provides convenient definition in <gdk/gdkversionmacros.h>
(already include by <gdk/gdk.h>) to check which API are available.

We only use the GdkMonitor API to get the monitor refresh rate.

Extract this code as a new gd_refresh_rate_millihz() function,
and check GDK_VERSION_3_22 is defined before calling its API.
If it is not defined, return 0. This is safe and fixes our build
failure (see https://travis-ci.org/qemu/qemu/builds/636992508).
