Also it's fixes issues about make check
Yonggang Luo (12):
configure: fixes dtc not cloned when running msys2 CI
meson: Convert undefsym.sh to undefsym.py
tcg: Fixes dup_const link error
tests: handling signal on win32 properly
configure: Fix include and linkage issue on msys2
block: Fixes nfs on msys2/mingw
osdep: These function are only available on Non-Win32 system.
ci: fixes msys2 build by upgrading capstone to 4.0.2
stubs: qemu_notify_event have no need to stub
meson: Fixes qapi tests.
tests: Disable test-image-locking that not works under Win32
ci: Enable msys2 ci in cirrus
