[PATCH v2] version: 26.11.0-rc0

[David Marchand <david.marchand@redhat.com>]

Start a new release cycle with empty release notes.

The ABI version becomes 27.0.
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.

Note: we need to bump the version for symbol compat in ethdev and net/mlx5
temporarily. Next commits will drop this compat entirely.

Changes since v1:
- bumped symbol exports for ethdev and net/mlx5,
