FYI/BRANCH: Patches applied to branch gdb-16-branch

[Joel Brobecker]

Hello,

FYI, a couple of patches I am about to push to the gdb-16-branch,
as part of our standard list of preparatory changes for GDB releases
on that branch:

  - [release/branch 1/2] Bump version to 16.0.90.DATE-git.
  - [release/branch 2/2] Set development mode to "off" by default.

Thank you,
