Drop the deprecated lm32 target

Target lm32 was deprecated in commit d8498005122, v5.2.0. See there
for rationale.

Some of its code lives on in device models derived from milkymist

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

hw/display: Add basic ATI VGA emulation

At least two machines, the PPC mac99 and MIPS fulong2e, have an ATI
gfx chip by default (Rage 128 Pro and M6/RV100 respectively) and
guests running on these and the PMON2000 firmware of the fulong2e
expect this to be available. Fortunately these are very similar chips
so they can be mostly emulated in the same device model. This patch
adds basic emulation of these ATI VGA chips.

While this is incomplete and currently only enough to run the MIPS
firmware and get framebuffer output with Linux, it allows the fulong2e
board to work more like the real hardware and having it in QEMU in
this state provides a way to experiment with it and allows others to
contribute to improve it. It is compiled for all archs but only the
fulong2e (which currently has no display output at all) is set to use
it by default (in a separate patch).

* The new qemu-trace-stap script makes it convenient to collect traces without
writing SystemTap scripts. See "man qemu-trace-stap" for details.

display: ensure qxl log_buf is a nul terminated string

The QXL_IO_LOG command allows the guest to send log messages to the host
via a buffer in the QXLRam struct. QEMU prints these to the console if
the qxl 'guestdebug' option is set to non-zero. It will also feed them
to the trace subsystem if any backends are built-in.

In both cases the log_buf data will get treated as being as a nul
terminated string, by the printf '%s' format specifier and / or other
code reading the buffer.

QEMU does nothing to guarantee that the log_buf really is nul terminated,
so there is potential for out of bounds array access.

This would affect any QEMU which has the log, syslog or ftrace trace
backends built into QEMU. It can only be triggered if the 'qxl_io_log'
trace event is enabled, however, so they are not vulnerable without
specific administrative action to enable this.

It would also affect QEMU if the 'guestdebug' parameter is set to a
non-zero value, which again is not the default and requires explicit
admin opt-in.
