Paolo Bonzini 63a7f85306 meson: fix missing preprocessor symbols 
While most libraries do not need a CONFIG_* symbol because the
"when:" clauses are enough, some do.  Add them back or stop
using them if possible.

In the case of libpmem, the statement to add the CONFIG_* symbol
was still in configure, but could not be triggered because it
checked for "no" instead of "disabled" (and it would be wrong anyway
since the test for the library has not been done yet).

Aaron Lindsay 787148bf92 plugins: Expose physical addresses instead of device offsets 
This allows plugins to query for full virtual-to-physical address
translation for a given `qemu_plugin_hwaddr` and stops exposing the
offset within the device itself. As this change breaks the API,
QEMU_PLUGIN_VERSION is incremented.

Alex Bennée a622d64eea plugins: new hwprofile plugin 
This is a plugin intended to help with profiling access to various
bits of system hardware. It only really makes sense for system
emulation.

It takes advantage of the recently exposed helper API that allows us
to see the device name (memory region name) associated with a device.

You can specify arg=read or arg=write to limit the tracking to just
reads or writes (by default it does both).

The pattern option:

  -plugin ./tests/plugin/libhwprofile.so,arg=pattern

will allow you to see the access pattern to devices, eg:

  gic_cpu @ 0xffffffc010040000
    off:00000000, 8, 1, 8, 1
    off:00000000, 4, 1, 4, 1
    off:00000000, 2, 1, 2, 1
    off:00000000, 1, 1, 1, 1

The source option:

  -plugin ./tests/plugin/libhwprofile.so,arg=source

will track the virtual source address of the instruction making the
access:

  pl011 @ 0xffffffc010031000
    pc:ffffffc0104c785c, 1, 4, 0, 0
    pc:ffffffc0104c7898, 1, 4, 0, 0
    pc:ffffffc010512bcc, 2, 1867, 0, 0

You cannot mix source and pattern.

Finally the match option allow you to limit the tracking to just the
devices you care about.
