Over the years, most parts of exec.c that were not specific to softmmu
have been moved to accel/tcg; what's left is mostly the low-level part
of the memory API, which includes RAMBlock and AddressSpaceDispatch.
However exec.c also hosts 4-500 lines of code for the target specific
parts of the CPU QOM object, plus a few functions for user-mode
emulation that do not have a better place (they are not TCG-specific so
accel/tcg/user-exec.c is not a good place either).
Move these parts to a new file, so that exec.c can be moved to
softmmu/physmem.c.

Environment variables like CFLAGS are easy to accidentally change. Meson
warns if that happens, but in a project with a lot of configuration that
is easy to lose. It is also surprising behavior since meson caches -D
options and remembers those on reconfiguration (which we rely on,
since configure options become -D options).
By placing the user-provided CFLAGS, CXXFLAGS and LDFLAGS in the
cross file, we at least get consistent behavior. These environment
variables are still ugly and not really recommended, but there are
distros that rely on them. For the gory details, refer to
https://github.com/mesonbuild/meson/issues/4664.

If the CFLAGS, CXXFLAGS or LDFLAGS variables are present in the environment,
any modification made within the configure script is passed down to Meson.
This is particularly undesirable for the "-pie" option, since it overrides
"-shared" and thus messes up the linker flags for shared modules.
Using a separate variable therefore fixes the bug, while clarifying that
the scope of these CFLAGS is just the configure script.
We also do not need to pass those variables in config-host.mak; they
were only used for printing the summary now that all submodules are
built with handwritten Meson rules). For now synthesize CFLAGS in the
configuration summary, the next patch will also pass them in a cleaner
way using the cross file.

There are better ways to do this, e.g. meson cmake subproject,
but that requires cmake 3.7 and some of our CI environments
only provide cmake 3.5.
Nor can we add a meson.build file to capstone/, because the git
submodule would then always report "untracked files". Fixing that
would require creating our own branch on the qemu git mirror, at
which point we could just as easily create a native meson subproject.
Instead, build the library via the main meson.build.
This improves the current state of affairs in that we will re-link
the qemu executables against a changed libcapstone.a, which we wouldn't
do before-hand. In addition, the use of the configuration header file
instead of command-line -DEFINES means that we will rebuild the
capstone objects with changes to meson.build.

The automatic dependency handling for Sphinx manuals only makes the output
depend on the input documentation files. This means that if you edit
the Python source of an extension then the documentation won't be
rebuilt.
Create a list of all the source files for the extensions and add
it to the dependencies for the manuals. This is similar to how we
handle the qapi_gen_depends list.
Because we don't try to identify which manuals are using which
Sphinx extensions, a change to the source of one extension will
always rebuild the entire manual set, not merely the manuals
which have changed. This is acceptable because we don't change
the extensions all that often.
