This reverts commit 48328880fddf0145bdccc499160fb24dfabfbd41.

The --ninja option doesn't need anymore because of upgrade meson to 0.55.2
At that version we can use ninjatool

We might actually get rid of ninjatool before QEMU 5.2 goes out, if we
decide to make Ninja a mandatory build dependency.  So we can hold on
patches 26 and 27.  Thanks for testing though!

I'm also not sure about patch 16, since that's not my area, but Daniel
and Ed both reviewed it so that's okay.

Finally, instead of checking !_WIN32 it's better to check CONFIG_POSIX
or CONFIG_WIN32.  That can be changed on commit though.

Everything else seems okay.  I'll wait a couple days and queue the whole
bunch up to patch 25.

That's not what the QEMU coding standards say; we generally don't test
the preprocessor symbols.  If we were to change to _WIN32, it should be
done at once on the whole codebase (don't do it :)).

I am hurry to revert --ninja option because when the meson are changed, the
make -j10 can not automatically re configure, that would raise ninja can
not found error

  CONFIG_WIN32  are rarely used, most of the are using _WIN32

My understanding is that with 0.55.2 you don't need --ninja at all (the
default search works), and also the previously configured build tree
should work.

What's the issue there?

Oh, I mis-understood the --ninja option, so the ninja option doesn't have
to be revert, but upgrade meson to 0.55.2 are necessary

Patch 13 definitely needs a replacement, and I think patch 2 should
likely go through the block tree instead...

But I recently started to experiment with these patches, too, and I
think I got a reasonable subset now which should be OK for getting
merged (e.g. disabling NFS and the crypto test in the CI for now). I'll
take those through my testing tree. The remaining work can then be done
on top later.

I am prepareing V9, and move nfs related things to the end  patch 13 are
re-implemented
