[Qemu-devel] [PATCH v3 00/18] Various build-sys and sanitizer related fixes

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

Hi,

This is a series that improves a bit the build system, and introduces
ASAN/UBSan by default when --enable-debug. Then it fixes a few leaks
that occur during make check: common and x86_64 target tests are leak
free after this series. The other targets will need some work to fix
the leaks & warnings.

v3:
- add ubsan too with --enable-debug, since it is recommended and has
  low runtime cost
- add a patch "compile with -Og or -O1 when --enable-debug", suggested
  by Paolo
- add 2 new fixes to pass full make check with asan/ubsan
- modify docker tests to run --enable-debug & asan with new test-debug
- add some r-b/a-b tags

v2:
- simplify "build-sys: silence make by default or V=0": make it a
  oneliner MAKEFLAGS, use --quiet.
- document print-VAR rule in docs/devel/build-system.txt
- fix ASAN coroutine instrumentation failure
- should fix builds on gcc 4.4.7 (centos 6)
- new coroutine test leak fix
- add some r-b tags
