e2982c3a27 exit if -drive specified is invalid instead of ignoring the "wrong" -drive
This fixes the problem when qemu continues even if -drive specification
is somehow invalid, resulting in a mess.  Applicable for both current
master and for stable-0.14 (and the same issue exist 0.13 and 0.12 too).

The prob can actually be seriuos: when you start guest with two drives
and make an error in the specification of one of them, and the guest
has something like a raid array on the two drives, guest may start failing
that array or kick "missing" drives which may result in a mess - this is
what actually happened to me, I did't want a resync at all, and a resync
resulted in re-writing (and allocating) a 4TB virtual drive I used for
testing, which in turn resulted in my filesystem filling up and whole
thing failing badly.  Yes it was just testing VM, I experimented with
larger raid arrays, but the end result was quite, well, unexpected.

46a4e4e608 block: Do not cache device size for removable media
The block layer caches the device size to avoid doing lseek(fd, 0,
SEEK_END) every time this value is needed.  For removable media the
device size becomes stale if a new medium is inserted.  This patch
simply prevents device size caching for removable media.

A smarter solution is to update the cached device size when a new medium
is inserted.  Given that there are currently bugs with CD-ROM media
change I do not want to implement that approach until we've gotten
things correct first.

d22b2f41c4 Do not delete BlockDriverState when deleting the drive
When removing a drive from the host-side via drive_del we currently have
the following path:

drive_del
qemu_aio_flush()
bdrv_close()    // zaps bs->drv, which makes any subsequent I/O get
                // dropped.  Works as designed
drive_uninit()
bdrv_delete()   // frees the bs.  Since the device is still connected to
                // bs, any subsequent I/O is a use-after-free.

The value of bs->drv becomes unpredictable on free.  As long as it
remains null, I/O still gets dropped, however it could become non-null
at any point after the free resulting SEGVs or other QEMU state
corruption.

To resolve this issue as simply as possible, we can chose to not
actually delete the BlockDriverState pointer.  Since bdrv_close()
handles setting the drv pointer to NULL, we just need to remove the
BlockDriverState from the QLIST that is used to enumerate the block
devices.  This is currently handled within bdrv_delete, so move this
into its own function, bdrv_make_anon().

The result is that we can now invoke drive_del, this closes the file
descriptors and sets BlockDriverState->drv to NULL which prevents futher
IO to the device, and since we do not free BlockDriverState, we don't
have to worry about the copy retained in the block devices.

We also don't attempt to remove the qdev property since we are no longer
deleting the BlockDriverState on drives with associated drives.  This
also allows for removing Drives with no devices associated either.

c8f930c0ee cpu-all.h: Remove unnecessary target-specific ifdef for CPU_QuadU
CPU_QuadU isn't used on all targets, but there's no harm in defining the
typedef anyway. It only needs to be guarded by CONFIG_SOFTFLOAT, because
softfloat-native doesn't have a float128 type. This avoids the need for
every new target which uses CPU_QuadU to add itself to an #ifdef in
what ought to be target-agnostic code.

9bcfc7daab ioapic: when switches to level trigger mode, interrupts raised repeatedly.
- the trigger mode is edge at first
- During initializatoin, the interrupt is raised as edge which is masked.
  The corresponding bit of irr is set.
- Then the mode is switched to level and it's unmasked.
- the bit of irr is set, so the interrupt is raised repeatedly by
  ioapic_service().
- OS considers that the irq line is broken and falls back to polling mode.

This patch fixes the issues.
After raising edige, clear the bit of irr.

622465e1fa target-arm/helper.c: For float-int conversion helpers pass ints as ints
Correct the argument and return types for the float<->int conversion helper
functions so that integer arguments and return values are declared as
uint32_t/uint64_t, not float32/float64. This allows us to remove the
hand-rolled functions which were doing bitwise copies between the types
via unions.

4a9f9cb24d target-arm: Use new softfloat min/max functions for VMAX, VMIN
Use the new softfloat min/max functions to implement the Neon VMAX
and VMIN instructions. This allows us to get the right behaviour
for NaN and negative zero.

274f1b041e softfloat: Add float*_min() and float*_max() functions
Add min and max operations to softfloat. This allows us to implement
propagation of NaNs and handling of negative zero correctly (unlike
the approach of having target helper routines return one of the operands
based on the result of a comparison op).
