[PATCH 0/7] build: replace ninjatool with ninja

[Paolo Bonzini]

This pull request is the last build system change for 5.2 from
me, and it is simple: similar to how we are invoking
ROM or tests/tcg "make" from the main Makefile, we now invoke ninja
to build QEMU.  Unlike those cases, however, build.ninja targets are
forwarded transparently.

The advantages cover various areas:

- maintainability: we drop scripts/ninjatool.py, which is
a large and hairy piece of code, and generally remove one
thing that can go wrong and one thing that is unique to QEMU;

- platform support: we remove the requirement for GNU make
3.82, which was annoying on Mac.  We also avoid bugs on Windows
due to meson emitting Windows rather than POSIX escapes (as
expected by Ninja) and ninjatool ignoring the difference;

- speed: invoking "configure" does not have to generate
44k lines of rules, while invoking "Make" does not anymore have
to parse 44k lines of rules.

- ease of use: Ninja tracks command lines, hence the problem
of static library changing the objects they hold goes away
