[PATCH 00/11] Fix qemu_strtosz() read-out-of-bounds

[Eric Blake]

This series blew up in my face when Hanna first pointed me to
https://gitlab.com/qemu-project/qemu/-/issues/1629

Basically, 'qemu-img dd bs=9.9e999' killed a sanitized build because
of a read-out-of-bounds (".9e999" parses as infinity, but qemu_strtosz
wasn't expecting ERANGE failure).

The overall diffstate is big, mainly because the unit tests needed a
LOT of work before I felt comfortable tweaking semantics in something
that is so essential to command-line and QMP parsing.

Eric Blake (11):
  test-cutils: Avoid g_assert in unit tests
  test-cutils: Use g_assert_cmpuint where appropriate
  test-cutils: Test integral qemu_strto* value on failures
  test-cutils: Add coverage of qemu_strtod
  test-cutils: Prepare for upcoming semantic change in qemu_strtosz
  test-cutils: Add more coverage to qemu_strtosz
  numa: Check for qemu_strtosz_MiB error
  cutils: Set value in all qemu_strtosz* error paths
  cutils: Set value in all integral qemu_strto* error paths
  cutils: Improve qemu_strtod* error paths
  cutils: Improve qemu_strtosz handling of fractions
