tcg: Allow the debug_frame data structure to be constant
Adjust the FDE to point to the code_buffer after we've copied it
to the image, rather than requiring that the backend set it prior.
This allows the backend to use read-only storage for its data.

Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h. This
minimizes the files that must be rebuilt when changing the macros
for file N.

- Check bdrv_op_is_blocked() in place of bdrv_in_use(bs).
The specific types are used, e.g. in place of starting block backup,
bdrv_op_is_blocked(bs, BLOCK_OP_TYPE_BACKUP, ...).
There is one exception in block_job_create, where
bdrv_op_blocker_is_empty() is used, because we don't know the operation

the check and move it to callers that _do_ know the type.
- Check bdrv_op_blocker_is_empty() in place of assert(!bs->in_use).
Note: there is only bdrv_op_block_all and bdrv_op_unblock_all callers at

block: Introduce op_blockers to BlockDriverState
BlockDriverState.op_blockers is an array of lists with BLOCK_OP_TYPE_MAX
elements. Each list is a list of blockers of an operation type
(BlockOpType), that marks this BDS as currently blocked for a certain
type of operation with reason errors stored in the list. The rule of
usage is:
* BDS user who wants to take an operation should check if there's any
blocker of the type with bdrv_op_is_blocked().
* BDS user who wants to block certain types of operation, should call
bdrv_op_block (or bdrv_op_block_all to block all types of operations,
which is similar to the existing bdrv_set_in_use()).
* A blocker is only referenced by op_blockers, so the lifecycle is
managed by caller, and shouldn't be lost until unblock, so typically
a caller does these:
- Allocate a blocker with error_setg or similar, call bdrv_op_block()
to block some operations.
- Hold the blocker, do his job.
- Unblock operations that it blocked, with the same reason pointer
passed to bdrv_op_unblock().
- Release the blocker with error_free().

aio: Fix use-after-free in cancellation path
The current flow of canceling a thread from THREAD_ACTIVE state is:
1) Caller wants to cancel a request, so it calls thread_pool_cancel.
2) thread_pool_cancel waits on the conditional variable
elem->check_cancel.
3) The worker thread changes state to THREAD_DONE once the task is
done, and notifies elem->check_cancel to allow thread_pool_cancel
to continue execution, and signals the notifier (pool->notifier) to
allow callback function to be called later. But because of the
global mutex, the notifier won't get processed until step 4) and 5)
are done.
4) thread_pool_cancel continues, leaving the notifier signaled, it
just returns to caller.
5) Caller thinks the request is already canceled successfully, so it
releases any related data, such as freeing elem->common.opaque.
6) In the next main loop iteration, the notifier handler,
event_notifier_ready, is called. It finds the canceled thread in
THREAD_DONE state, so calls elem->common.cb, with an (likely)
dangling opaque pointer. This is a use-after-free.
Fix it by calling event_notifier_ready before leaving
thread_pool_cancel.
Test case update: This change will let cancel complete earlier than
test-thread-pool.c expects, so update the code to check this case: if
it's already done, done_cb sets .aiocb to NULL, skip calling
bdrv_aio_cancel on them.

target-arm/translate.c: Use get_mem_index() for SRS memory accesses
The SRS instruction was using a hardcoded 0 for the memory
accesses. This happens to be OK since the SRS instruction is
UNPREDICTABLE in User and System modes, but is awkward if we
want to rearrange the MMU index uses. Switch to using
get_mem_index() like all the other accesses.

target-arm: implement CPACR register logic for ARMv7
In ARMv7 the CPACR register allows to control access rights to
coprocessor 0-13 interfaces. Bits corresponding to unimplemented
coprocessors should be RAZ/WI. Bits ASEDIS, D32DIS, TRCDIS are
UNK/SBZP if VFP is not implemented and RAO/WI in some cases.
Treating TRCDIS as RAZ/WI since we neither implement a trace
macrocell nor a CP14 interface to the trace macrocell registers.
Since CPACR bits for VFP/Neon access are honoured with the CPACR_FPEN
bit in the TB flags, flushing the TLB is not necessary anymore.

The pxa2xx palette entry "16bpp plus transparency" format is

xxxxxxxTRRRRRR00GGGGGG00BBBBBB00.
Correct errors in the code for reading these and converting
them to the internal format. In particular, the buggy code
was attempting to mask out bit 24 of a uint16_t, which
Coverity spotted as an error.

target-arm: Fix segfault on startup when KVM enabled
Commit 50a2c6e55fa introduced a bug where QEMU would segfault on startup
when using KVM on ARM hosts, because kvm_arm_reset_cpu() accesses
cpu->cpreg_reset_values, which is not allocated before
kvm_arch_init_vcpu(). Fix this by not calling cpu_reset() until after
qemu_init_vcpu().
