[PATCH 1/2] version: 25.11.0-rc0

[PATCH 1/2] version: 25.11.0-rc0

[David Marchand]

Start a new release cycle with empty release notes.

The ABI version becomes 26.0.
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.

[PATCH 2/2] net: remove v25 ABI compatibility

[David Marchand]

Now that the ABI has been bumped to 26, we can drop compatibility
symbols for the CRC API.

The logtype is not used anymore and can be removed.
