  block/file-win32: add reopen handlers (2021-09-01 14:38:08 +0200)


**Note:** I’ve signed the pull request tag with my new GPG key, which I
have uploaded here:

  https://xanclic.moe/A1FA40D098019CDF

Included in that key should be the signature I made with my old key
(F407DB0061D5CF40), and I hope that’s sufficient to establish a
reasonable level of trust.

(I’ve also tried uploading this key to several keyservers, but it
appears to me that keyservers are kind of a thing of the past now,
especially when it comes to uploading keys with signatures on them...)

----------------------------------------------------------------
Block patches:
- Make the backup-top filter driver available for user-created block
  nodes (i.e. via blockdev-add)
- Allow running iotests with gdb or valgrind being attached to qemu
  instances
- Fix the raw format driver's permissions: There is no metadata, so we
  only need WRITE or RESIZE when the parent needs it
- Basic reopen implementation for win32 files (file-win32.c) so that
  qemu-img commit can work
- uclibc/musl build fix for the FUSE export code
- Some iotests delinting
- block-hmp-cmds.c refactoring
