PPC: dbdma: Support more multi-issue DMA requests
A DMA request can happen for data that hasn't been completely been
provided by the IDE core yet. For example
- DBDMA request for 0x1000 bytes
- IDE request for 1 sector
- DBDMA wants to read 0x1000 bytes (8 sectors) from bdrv
- breakage
Instead, we should truncate our bdrv request to the maximum number
of sectors we're allowed to read at that given time. Once that transfer
is through, we will fall into our recently introduced waiting logic.
- DBDMA requests for 0x1000 bytes
- IDE request for 1 sector
- DBDMA wants to read MIN(0x1000, 1 * 512) bytes
- DBDMA finishes reading, indicates to IDE core that transfer is complete
- IDE request for 7 sectors
- DBDMA finishes the DMA

PPC: dbdma: Support unaligned DMA access
The DBDMA engine really just reads bytes from a producing device (IDE
in our case) and shoves these bytes into memory. It doesn't care whether
any alignment takes place or not.
Our code today however assumes that block accesses always happen on
sector (512 byte) boundaries. This is a fair assumption for most cases.
However, Mac OS X really likes to do unaligned, incomplete accesses
that it finishes with the next DMA request.
So we need to read / write the unaligned bits independent of the actual
asynchronous request, because that one can only handle 512-byte-aligned
data. We also need to cache these unaligned sectors until the next DMA
request, at which point the data might be successfully flushed from the
pipe.

Fix -machine options accel, kernel_irqchip, kvm_shadow_mem
Multiple -machine options with the same ID are merged. All but the
one without an ID are to be silently ignored.
In most places, we query these options with a null ID. This is
correct.
In some places, we instead query whatever options come first in the
list. This is wrong. When the -machine processed first happens to
have an ID, options are taken from that ID, and the ones specified
without ID are silently ignored.
Example:
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine id=foo,accel=kvm,usb=on -machine accel=xen
$ upstream-qemu -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on
$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=kvm,usb=on

$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine id=foo -machine accel=kvm,usb=on

(qemu) q
$ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -machine accel=xen -machine id=foo,accel=kvm,usb=on
xc: error: Could not obtain handle on privileged command interface (2 = No such file or directory): Internal error
xen be core: can't open xen interface
failed to initialize Xen: Operation not permitted
Option usb is queried correctly, and the one without an ID wins,
regardless of option order.
Option accel is queried incorrectly, and which one wins depends on
option order and ID.
Affected options are accel (and its sugared forms -enable-kvm and
-no-kvm), kernel_irqchip, kvm_shadow_mem.
Additionally, option kernel_irqchip is normally on by default, except
it's off when no -machine options are given. Bug can't bite, because
kernel_irqchip is used only when KVM is enabled, KVM is off by
default, and enabling always creates -machine options. Downstreams
that enable KVM by default do get bitten, though.
Use qemu_get_machine_opts() to fix these bugs.

qemu-option: Fix qemu_opts_set_defaults() for corner cases
Commit 4f6dd9a changed the initialization of opts in opts_parse() to
this:
if (defaults) {
if (!id && !QTAILQ_EMPTY(&list->head)) {
opts = qemu_opts_find(list, NULL);
} else {
opts = qemu_opts_create(list, id, 0);
}
} else {
opts = qemu_opts_create(list, id, 1);
}
Same as before for !defaults.
If defaults is true, and params has no ID, and options exist, we use
the first assignment. It sets opts to null if all options have an ID.
opts_parse() then returns null. qemu_opts_set_defaults() asserts the
value is non-null. It's the only caller that passes true for
defaults.
To reproduce, try "-M xenpv -machine id=foo" (yes, "id=foo" is silly,
but it shouldn't crash).
I believe the function attempts to do the following:
If options don't yet exist, create new options
Else, if defaults, modify the existing options
Else, if list->merge_lists, modify the existing options
Else, fail
A straightforward call of qemu_opts_create() does exactly that.

tcg: Move the CIE and FDE header definitions to common code
These will necessarily be the same layout for all hosts. This limits
the amount of boilerplate required to implement jit debug for a host.

tcg: Fix high_pc fields in .debug_info
I don't think the debugger actually looks at this for anything,
using the correct .debug_frame contents, but might as well get
it all correct.

tcg-arm: Use AT_PLATFORM to detect the host ISA
With this we can generate armv7 insns even when the OS compiles for a
lower common denominator. The macros are arranged so that when we do
compile for a given ISA, all of the runtime checks for that ISA are
optimized away.

tcg-arm: Simplify logic in detecting the ARM ISA in use
GCC 4.8 defines a handy __ARM_ARCH symbol that we can use, which
will make us nicely forward compatible with ARMv8 AArch32.

tcg-arm: Make use of conditional availability of opcodes for divide
We can now detect and use divide instructions at runtime, rather than

Expand the definition of "not present" to include "should not be present".
This means we can simplify the logic surrounding the generic tcg opcodes

This allows TCG_TARGET_HAS_* to be a variable rather than a constant,
