Add reference count to block job, meanwhile move the ownership of the
reference to job->bs from the caller (which is released in two
completion callbacks) to the block job itself. It is necessary for
block_job_complete_sync to work, because block job shouldn't live longer
than its bs, as asserted in bdrv_delete.
Now block_job_complete_sync can be simplified.

These structures are misnomers, somewhat.
(1) BlockTransactionState is not state for a transaction,
but is rather state for a single transaction action.
Rename it "BlkActionState" to be more accurate.
(2) The BdrvActionOps describes operations for the BlkActionState,
above. This name might imply a 'BdrvAction' or a 'BdrvActionState',
which there isn't.
Rename this to 'BlkActionOps' to match 'BlkActionState'.
Lastly, update the surrounding in-line documentation and comments
to reflect the current nature of how Transactions operate.
This patch changes only comments and names, and should not affect
behavior in any way.

The "need_check_timer" is used to clear the "NEED_CHECK" flag in the

compliance to the bdrv_drain semantics we should make sure it remains

Drivers can have internal request sources that generate IO, like the
need_check_timer in QED. Since we want quiesced periods that contain
nested event loops in block layer, we need to have a way to disable such
event sources.
Block drivers must implement the "bdrv_drain" callback if it has any
internal sources that can generate I/O activity, like a timer or a
worker thread (even in a library) that can schedule QEMUBH in an
asynchronous callback.
Update the comments of bdrv_drain and bdrv_drained_begin accordingly.
Like bdrv_requests_pending(), we should consider all the children of bs.
Before, the while loop just works, as bdrv_requests_pending() already
tracks its children; now we mustn't miss the callback, so recurse down
explicitly.

This follows the previous patches, where support for migrating the
entire MAC registers' array, and some new MAC registers were introduced.
This patch introduces the e1000-specific boolean parameter
"extra_mac_registers", which is on by default. Setting it to off will
enable migration to older versions of QEMU, but will disable the read
and write access to the new registers, that were introduced since adding
the ability to migrate the entire MAC array.
Example for usage to enable backward compatibility and to disable the
new MAC registers:
qemu-system-x86_64 -device e1000,extra_mac_registers=off,... ...
As mentioned above, the default value is "on".

These registers appear in Intel's specs, but were not implemented.
These registers are now implemented trivially, i.e. they are initiated
with zero values, and if they are RW, they can be written or read by the
driver, or read only if they are R (essentially retaining their zero
values). For these registers no other procedures are performed.
For the trivially implemented Diagnostic registers, a debug warning is
produced on read/write attempts.
PLEASE NOTE: these registers will not be active, nor will migrate, until
a compatibility flag will be set (in a later patch in this series).

The array of uint8_t's which is introduced here, contains access metadata
about the MAC registers: if a register is accessible, but partly implemented,
or if a register requires a certain compatibility flag in order to be
accessed. Currently, 6 hypothetical flags are supported (3 exist for e1000
so far) but in the future, if more than 6 flags will be needed, the datatype
of this array can simply be swapped for a larger one.
This patch is intended to solve the following current problems:
1) In a scenario of migration between different versions of QEMU, which
differ by the MAC registers implemented in them, some registers need not to
be active if a compatibility flag is set, in order to preserve the machine's
state perfectly for the older version. Checking this for each register
individually, would create a lot of clutter in the code.
2) Some registers are (or may be) only partly implemented (e.g.
placeholders that allow reading and writing, but lack other functions).
In such cases it is better to print a debug warning on read/write attempts.
As above, dealing with this functionality on a per-register level, would
require longer and more messy code.

This patch makes the migration of the entire array of MAC registers
possible during live migration. The entire array is just 128 KB long, so
practically no penalty should be felt when transmitting it, additionally
to the previously transmitted individual registers. The advantage here is
eliminating the need to introduce new vmstate subsections in the future,
when additional MAC registers will be implemented.
Backward compatibility is preserved by introducing a e1000-specific
boolean parameter (in a later patch), which will be on by default.
Setting it to off would enable migration to older versions of QEMU.
Additionally, this parameter will be used to control the access to the
extra MAC registers in the future.

At the moment get_monitor_def() returns only registers from statically
defined monitor_defs array. However there is a lot of BOOK3S SPRs
which are not in the list and cannot be printed from the monitor.
This adds a new target platform hook - target_get_monitor_def().
The hook is called if a register was not found in the static
array returned by the target_monitor_defs() hook.
The hook is only defined for POWERPC, it returns registered
SPRs and fails on unregistered ones providing the user with information
on what is actually supported on the running CPU. The register value is
saved as uint64_t as it is the biggest supported register size;
target_ulong cannot be used because of the stub - it is in a "common"
code and cannot include "cpu.h", etc; this is also why the hook prototype
is redefined in the stub instead of being included from some header.
This replaces static descriptors for GPRs, FPRs, SRs with a helper which
looks for a value in a corresponding array in the CPUPPCState.
The immediate effect is that all 32 SRs can be printed now (instead of 16);
later this can be reused for VSX or TM registers.
This replaces callbacks for MSR and XER with static descriptors in
monitor_defs as they are stored in CPUPPCState.
While we are here, this adds "cr" as a synonym of "ccr".

Fix the counter loading logic and enable the T2 interrupt when the timer
expires. Otherwise MacOS 9 hangs on boot.

These are used by MacOS 9 on boot. Here we return an error except for 4-byte

According to comments in MOL, the response to a CUDA_PACKET should be one of
the following:
Reply: (CUDA_PACKET, status, cmd)
Error: (ERROR_PACKET, status, CUDA_PACKET, cmd)
Update cuda_receive_packet() accordingly to reflect this in order to make
MacOS 9 happy.

According to MOL, ADB error packets should be of the form (type, status, cmd)
rather than just (type, status). This fixes ADB device detection under MacOS 9.

The mac99 machines always have a USB controller. Usually not having one around
doesn't hurt quite as much, but Mac OS 9 really really wants one or it crashes
on bootup.
So always add OHCI to make it happy.

The lswx instruction checks whether the desired string actually fits
into all defined registers. Unfortunately it does the calculation wrong,
resulting in illegal instruction traps for loads that really should fit.
Fix it up, making Mac OS happier.

According to the ISA setting the Rc bit on mtspr is undefined behavior.
Real 750 hardware simply ignores the bit and doesn't touch cr0 though.
Unfortunately, Mac OS 9 relies on this fact and executes a few mtspr
instructions (to set XER for example) with Rc set.
So let's handle the bit the same way hardware does and ignore it.
