Markus Armbruster b15e402fc8 trace-events: Fix attribution of trace points to source
Some trace points are attributed to the wrong source file.  Happens
when we neglect to update trace-events for code motion, or add events
in the wrong place, or misspell the file name.

Clean up with help of scripts/cleanup-trace-events.pl.  Funnies
requiring manual post-processing:

* accel/tcg/cputlb.c trace points are in trace-events.

* block.c and blockdev.c trace points are in block/trace-events.

* hw/block/nvme.c uses the preprocessor to hide its trace point use
  from cleanup-trace-events.pl.

* hw/tpm/tpm_spapr.c uses pseudo trace point tpm_spapr_show_buffer to
  guard debug code.

* include/hw/xen/xen_common.h trace points are in hw/xen/trace-events.

* linux-user/trace-events abbreviates a tedious list of filenames to
  */signal.c.

* net/colo-compare and net/filter-rewriter.c use pseudo trace points
  colo_compare_miscompare and colo_filter_rewriter_debug to guard
  debug code.

Eduardo Habkost db1015e92e Move QOM typedefs and add missing includes
Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.

Patch generated using:

 $ ./scripts/codeconverter/converter.py -i \
   --pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')

which will split "typdef struct { ... } TypedefName"
declarations.

Followed by:

 $ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
    $(git grep -l '' -- '*.[ch]')

which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Similarly, if the Select (SEL) field is set to request saved values, the

Klaus Jensen 46ac29c38b hw/block/nvme: move NvmeFeatureVal into hw/block/nvme.h
The NvmeFeatureVal does not belong with the spec-related data structures
in include/block/nvme.h that is shared between the block-level nvme
driver and the emulated nvme device.

Move it into the nvme device specific header file as it is the only
user of the structure. Also, remove the unused members.

Klaus Jensen 5d5a53302b hw/block/nvme: add support for the asynchronous event request command
Add support for the Asynchronous Event Request command. Required for
compliance with NVMe revision 1.3d. See NVM Express 1.3d, Section 5.2
("Asynchronous Event Request command").

Mostly imported from Keith's qemu-nvme tree. Modified with a max number
of queued events (controllable with the aer_max_queued device
parameter). The spec states that the controller *should* retain
events, so we do best effort here.

Klaus Jensen 94a7897c41 hw/block/nvme: add support for the get log page command
Add support for the Get Log Page command and basic implementations of
the mandatory Error Information, SMART / Health Information and Firmware
Slot Information log pages.

In violation of the specification, the SMART / Health Information log
page does not persist information over the lifetime of the controller
because the device has no place to store such persistent state.

Note that the LPA field in the Identify Controller data structure
intentionally has bit 0 cleared because there is no namespace specific
information in the SMART / Health information log page.

Required for compliance with NVMe revision 1.3d. See NVM Express 1.3d,
Section 5.14 ("Get Log Page command").

Eduardo Habkost b694ed1f56 swim: Rename struct SWIM to Swim
Currently we have a SWIM typedef and a SWIM type checking macro,
but OBJECT_DECLARE* would transform the SWIM macro into a
function, and the function name would conflict with the SWIM
typedef name.

Rename the struct and typedef to "Swim". This will make future
conversion to OBJECT_DECLARE* easier.
