This moves library functions used by both QEMU and the QEMU tools,
such as qemu-img, qemu-nbd etc. from osdep.c to oslib-{posix,win32}.c

In addition it introduces oslib-obj.y to the Makefile set to be
included by the various targets, instead of relying on these library
functions magically getting included via block-obj-y.

fprintf_function uses format checking with GCC_FMT_ATTR.

It is declared in qemu-common.h and used in cpu-all.h
(which is included from cpu.h), so qemu-common.h must
be included earlier. Some redundant include statements
for standard include files were removed.

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.

The formerly used dyngen code did not work with

Tests with Linux, OSX and Win32 show that this
restriction is no longer needed.

So we hopefully can remove that special piece of code.

The werror option now affects not only write requests, but also flush requests.
Previously, it was not possible to stop a VM on a failed flush.
Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Instead of always assuming success for bdrv_aio_flush, actually do something
with the error. This respects the werror option and accordingly ignores the
error, reports it to the guest or stops the VM and retries after cont.

Ignoring the error is trivial, obviously. For stopping the VM and retrying
later old code can be reused, but we need to introduce a new status for "retry
a flush". For reporting to the guest, fortunately the same action is required
as for a failed read/write (status = DRDY | ERR, error = ABRT), so this code
can be reused as well.

The old -B option caused a backing file to be used for the converted image and
to avoid copying clusters from the old backing file. When replaced with
-obacking_file, qemu-img convert does assign the backing file to the new image,
but it doesn't realize that it should avoid copying clusters from the backing
file.

This patch checks the -o options for a backing_file and applies the same logic
as for -B in this case.

The L1 table grow operation includes a size calculation that bumps up
the new L1 table size in order to anticipate the size needs of vmstate
data.  This helps reduce the number of times that the L1 table has to be
grown when vmstate data is appended.

This size overhead is not necessary during image creation,
bdrv_truncate(), or snapshot goto operations.  In fact, existing
qemu-iotests that exercise table growth are no longer able to trigger it
because image creation preallocates an L1 table that is too large after
changes to qcow_create2().

This patch keeps the size calculation but also adds exact growth for
callers that do not want to inflate the L1 table size unnecessarily.
