plugins: move the more involved plugins to contrib We have an exploding complexity problem in the testing so lets just move the more involved plugins into contrib. tests/plugins still exist for the basic plugins that exercise the API. We restore the old pre-meson style Makefile for contrib as it also doubles as a guide for out-of-tree plugin builds. While we are at it add some examples to the documentation and a specific plugins build target.

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.

plugins: Added a new cache modelling plugin Added a cache modelling plugin that uses a static configuration used in many of the commercial microprocessors and uses random eviction policy.

build: move warning flag selection to meson Meson already knows to test with the positive form of the flag, which simplifies the test. Warnings are now tested explicitly for the C++ compiler, instead of hardcoding those that are only available for the C language. At this point all compiler flags in QEMU_CFLAGS are global and only depend on the OS. No feature tests are performed in configure.
