osdep.h pulls in glib.h via glib-compat.h, so add it to the list of
includes that we remove. (This then means we must avoid running
clean-includes on glib-compat.h or it will delete the glib.h include.)

Commit 57cb38b3 included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

As soon as setjmp.h is included from qemu/osdep.h, those old include
statements are no longer needed.

Add also setjmp.h to the list in scripts/clean-includes.

include/config.h just includes config-target.h (and used to also
include config-host.h).
It is now obsolete and unused, because osdep.h does this job, so
remove it.

Ignore files which have a .inc.c extension -- these are not headers
but they are not standalone C source files either, so we can't make
any automated decisions about what #include directives they should
have.

Add a --all option which will run the script on every C

Enhance clean-includes to handle header files as well as .c source
files. For headers we merely remove all the redundant #include
lines, including any includes of qemu/osdep.h itself.

There is a simple mollyguard on the include file processing to
skip a few key headers like osdep.h itself, to avoid producing
bad patches if the script is run on every file in include/.

Add a new scripts/clean-includes, which can be used to automatically
ensure that a C source file includes qemu/osdep.h first and doesn't
then include any headers which osdep.h provides already.
