target/sh4: fetch code with translator_ld

There is a small wrinkle with the gUSA instruction. The translator
effectively treats a (known) gUSA sequence as a single instruction.
For the purposes of the plugin we end up with a long multi-instruction
qemu_plugin_insn.

If the known sequence isn't detected we shall never run this
translation anyway.

plugin-gen: add module for TCG-related code

We first inject empty instrumentation from translator_loop.
After translation, we go through the plugins to see what
they want to register for, filling in the empty instrumentation.
If if turns out that some instrumentation remains unused, we
remove it.

This approach supports the following features:

- Inlining TCG code for simple operations. Note that we do not
  export TCG ops to plugins. Instead, we give them a C API to
  insert inlined ops. So far we only support adding an immediate
  to a u64, e.g. to count events.

- "Direct" callbacks. These are callbacks that do not go via
  a helper. Instead, the helper is defined at run-time, so that
  the plugin code is directly called from TCG. This makes direct
  callbacks as efficient as possible; they are therefore used
  for very frequent events, e.g. memory callbacks.

- Passing the host address to memory callbacks. Most of this
  is implemented in a later patch though.

- Instrumentation of memory accesses performed from helpers.
  See the corresponding comment, as well as a later patch.

qcow2: Fix corruption bug in qcow2_detect_metadata_preallocation()

qcow2_detect_metadata_preallocation() calls qcow2_get_refcount() which
requires s->lock to be taken to protect its accesses to the refcount
table and refcount blocks. However, nothing in this code path actually
took the lock. This could cause the same cache entry to be used by two
requests at the same time, for different tables at different offsets,
resulting in image corruption.

As it would be preferable to base the detection on consistent data (even
though it's just heuristics), let's take the lock not only around the
qcow2_get_refcount() calls, but around the whole function.

This patch takes the lock in qcow2_co_block_status() earlier and asserts
in qcow2_detect_metadata_preallocation() that we hold the lock.

doc: Describe missing generic -blockdev options

We added more generic options after introducing -blockdev and forgot to
update the documentation (man page and --help output) accordingly. Do
that now.

iotests: Skip read-only cases in 118 when run as root

Some tests in 118 use chmod to remove write permissions from the file
and assume that the image can indeed not be opened read-write
afterwards. This doesn't work when the test is run as root, because root
can still open the file as writable even when the permission bit isn't
set.

Introduce a @skip_if_root decorator and use it in 118 to skip the tests
in question when the script is run as root.

qapi: add support for blkreplay driver

This patch adds support for blkreplay driver to the blockdev options.
Now blkreplay can be used with -blockdev command line option
in the following format:
-blockdev driver=blkreplay,image=file-node-name,node-name=replay-node-name

This file creates the BCM2836/BCM2837 blocks.
The biggest differences with the BCM2838 we are going to add, are
the base addresses of the interrupt controller and the peripherals.
Add these addresses in the BCM283XInfo structure to make this
block more modular. Remove the MCORE_OFFSET offset as it is
not useful and rather confusing.
