[PATCH 00/26] target/mips: Re-org to allow KVM-only builds

[Philippe Mathieu-Daudé]

TL;DR:

This series restrict TCG-specific objects by moving them to
the tcg/ subdir. Code is moved around to satisfy 3 cases:
{ generic sysemu / tcg sysemu / tcg user}.

Hi,

This series move the MIPS TCG files under target/mips/tcg/.
tcg/ is split into {sysemu and user}, and code common to
both user/sysemu is left under tcg/ root.

Non-user code is moved to sysemu/ (common to TCG and KVM).

- Patches 1 & 6 are Meson generic
- Patches 2 to 5 move generic symbols around to satisfly KVM linking
- Patch 8 introduces tcg-internal.h where we'll move TCG specific
  prototypes from the current big internal.h
- Patches 9-24 move code by topic (first user, then sysemu, then tcg)
- Patch 25 restrict TCG specific machines to TCG (to actually
  only build malta/loongson3-virt machines when restricted to KVM)
- Patch 26 finally add a CI job with "KVM-only" config:
  https://gitlab.com/philmd/qemu/-/jobs/1189874868 (12min 5sec)

Diffstat is not that bad, and many #ifdef'ry removed.

Please review,

Phil.
