This patch adds the new field 'idle_time_ns' to the BlockDeviceStats structure, indicating the time that has passed since the previous I/O operation. It also adds the block_acct_idle_time_ns() call, to ensure that all references to the clock type used for accounting are in the same place. This will later allow us to use a different clock for iotests.

Its value is still QEMU_CLOCK_REALTIME, but having it in a variable will allow us to change its value easily in the future when running in qtest mode.

BlockAcctStats contains statistics about the data transferred from and to the device; wr_highest_sector does not fit in with the rest. Furthermore, those statistics are supposed to be specific for a certain device and not necessarily for a BDS (see the comment above bdrv_get_stats()); on the other hand, wr_highest_sector may be a rather important information to know for each BDS. When BlockAcctStats is finally removed from the BDS, we will want to keep wr_highest_sector in the BDS. Finally, wr_highest_sector is renamed to wr_highest_offset and given the appropriate meaning. Externally, it is represented as an offset so there is no point in doing something different internally. Its definition is changed to match that in qapi/block-core.json which is "the offset after the greatest byte written to". Doing so should not cause any harm since if external programs tried to calculate the volume usage by (wr_highest_offset + 512) / volume_size, after this patch they will just assume the volume to be full slightly earlier than before.

Use the external qemu-timer API instead. No one else should be calling cpu_get_clock(), get_clock() and get_clock_realtime() directly; they are internal functions and they should be confined to qemu-timer.c and cpus.c (where the icount implementation resides). All accesses should go through qemu_clock_get_ns.

This is the next step for decoupling block accounting functions from BlockDriverState. In a future commit the BlockAcctStats structure will be moved from BlockDriverState to the device models structures. Note that bdrv_get_stats was introduced so device models can retrieve the BlockAcctStats structure of a BlockDriverState without being aware of it's layout. This function should go away when BlockAcctStats will be embedded in the device models structures.

The middle term goal is to move the BlockAcctStats structure in the device models. (Capturing I/O accounting statistics in the device models is good for billing) This patch make a small step in this direction by removing a reference to BDRV.

The plan is to add new accounting metrics (latency, invalid requests, failed requests, queue depth) and block.c is overpopulated so it will be better to work in a separate module. Moreover the long term plan is to have statistics in each of the BDS of the graph for metrology purpose; this means that the device model statistics must move from the topmost BDS to the device model. So we need to decouple the statistic code from BlockDriverState. This is another argument for the extraction of the code in a separate module.

Allow the clock_gettime() code using monotonic clock to be utilized on more POSIX compliannt OS's. This started as a fix for OpenBSD which was listed in one function as part of the previous hard coded list of OS's for the functions to support but not in the other.

Move timer init functions to a new file, qemu-timer-common.c. Make other critical timer functions inlined to preserve performance in qemu-timer.c, also move muldiv64() (used by the inline functions) to qemu-timer.h. Adjust block/raw-posix.c and simpletrace.c to use get_clock() directly. Remove a similar/duplicate definition in qemu-tool.c. Adjust hw/omap_clk.c to include qemu-timer.h because muldiv64() is used there. After this change, tracing can be used also for user code and simpletrace on Win32.
