[PATCH v10 0/4] cutils: Introduce bundle mechanism

[Akihiko Odaki <akihiko.odaki@gmail.com>]

Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.

It is a general mechanism and can find any files located relative
to the installation tree. The build tree must have a new directory,
qemu-bundle, to represent what files the installation tree would
have for reference by the executables.

Note that this abandons compatibility with Windows older than 8 to use
PathCchSkipRoot(). The extended support for the prior version, 7 ended
more than 2 years ago, and it is unlikely that anyone would like to run
the latest QEMU on such an old system.

v10:
* Update destdir_join() in scripts/symlink-install-tree.py with the
  latest implementation from Meson:
  https://github.com/mesonbuild/meson/pull/10531

v9:
* Update _WIN32_WINNT in include/qemu/osdep.h (Thomas Huth)

v8:
* Pass absolute paths to get_relocated_path() (Paolo Bonzini)
* Use meson introspection (Paolo Bonzini)
* Drop "qga: Relocate a path emitted in the help text" as it is no longer
  relevant for the bundle mechanism.

v7: Properly fix --firmwarepath (Daniel P. Berrangé)

v6: Reuse get_relocated_path() in find_bundle() (Paolo Bonzini)

v5:
* Prefer qemu-bundle if it exists. (Daniel P. Berrangé)
* Check install_blobs option before installing BIOSes (Paolo Bonzini)
* Add common code to set up qemu-bundle to the top level meson.build
  (Paolo Bonzini)

v4:
* Add Daniel P. Berrangé to CC. Hopefully this helps merging his patch:

* Rebased to the latest QEMU.

v3:
* Note that the bundle mechanism is for any files located relative to the
  installation tree including but not limited to datadir. (Peter Maydell)
* Fix "bridge" typo (Philippe Mathieu-Daudé)

v2: Rebased to the latest QEMU.
