meson: subprojects: replace submodules with wrap files
Compared to submodules, .wrap files have several advantages:
* option parsing and downloading is delegated to meson
* the commit is stored in
meson: subprojects: replace submodules with wrap files
Compared to submodules, .wrap files have several advantages:
* option parsing and downloading is delegated to meson
* the commit is stored in a text file instead of a magic entry in the git tree object
* we could stop shipping external dependencies that are only used as a fallback, but not break compilation on platforms that lack them. For example it may make sense to download dtc at build time, controlled by --enable-download, even when building from a tarball. Right now, this patch does the opposite: make-release treats dtc like libvfio-user (which is not stable API and therefore hasn't found its way into any distros) and keycodemap (which is a copylib, for better or worse).
dependency() can fall back to a wrap automatically. However, this is only possible for libraries that come with a .pc file, and this is not very common for libfdt even though the upstream project in principle provides it; it also removes the control that we provide with --enable-fdt={system,internal}. Therefore, the logic to pick system vs. internal libfdt is left untouched.
--enable-fdt=git is removed; it was already a synonym for --enable-fdt=internal.
