  call bdrv_drain_all() even if the vm is stopped

There are still I/O operations when the vm is stopped. For example,
stop the vm, and do block migration. In this case, we don't drain all
I/O operation, and may meet the following problem:

qemu-system-x86_64: migration/block.c:731: block_save_complete: Assertion 
`block_mig_state.submitted == 0' failed.

  Revert "exec: silence hugetlbfs warning under qtest"

This reverts commit 1c7ba94a184df1eddd589d5400d879568d3e5d08.

That commit changed QEMU initialization order from

 - object-initial, chardev, qtest, object-late

to

 - chardev, qtest, object-initial, object-late

This breaks chardev setups which need to rely on objects
having been created. For example, when chardevs use TLS
encryption in the future, they need to have tls credential
objects created first.

This revert, restores the ordering introduced in

  exec: remove warning about mempath and hugetlbfs

The gethugepagesize() method in exec.c printed a warning if
the file path for "-mem-path" or "-object memory-backend-file"
was not on a hugetlbfs filesystem. This warning is bogus, because
QEMU functions perfectly well with the path on a regular tmpfs
filesystem. Use of hugetlbfs vs tmpfs is a choice for the management
application or end user to make as best fits their needs. As such it
is inappropriate for QEMU to have an opinion on whether the user's
choice is right or wrong in this case.

  target-sparc: fix 32-bit truncation in fpackfix

This is reported by Coverity.  The algorithm description at
ftp://ftp.icm.edu.pl/packages/ggi/doc/hw/sparc/Sparc.pdf suggests
that the 32-bit parts of rs2, after the left shift, is treated
as a 64-bit integer.  Bits 32 and above are used to do the
saturating truncation.

Make sure that we actually have a device when checking the aio
context. Otherwise guests could trigger QEMU crashes.

  target-i386: kvm: Abort if MCE bank count is not supported by host

Instead of silently changing the number of banks in mcg_cap based
on kvm_get_mce_cap_supported(), abort initialization if the host
doesn't support MCE_BANKS_DEF banks.

Note that MCE_BANKS_DEF was always 10 since it was introduced in
QEMU, and Linux always returned 32 at KVM_CAP_MCE since
KVM_CAP_MCE was introduced, so no behavior is being changed and
the error can't be triggered by any Linux version. The point of
the new check is to ensure we won't silently change the bank
count if we change MCE_BANKS_DEF or make the bank count
configurable in the future.

  target-i386: kvm: Use env->mcg_cap when setting up MCE

When setting up MCE, instead of using the MCE_*_DEF macros
directly, just filter the existing env->mcg_cap value.

As env->mcg_cap is already initialized as
MCE_CAP_DEF|MCE_BANKS_DEF at target-i386/cpu.c:mce_init(), this
doesn't change any behavior. But it will allow us to change
mce_init() in the future, to implement different defaults
depending on CPU model, machine-type or command-line parameters.
