llama : fix llama_copy_state_data with fragmented KV cache (#5840)

The row size of the saved states was based on kv_self.head while
it should be based on llama_kv_cache_cell_max.

Existing session files should still work.

* llama : fix llama_kv_cache_cell_max inability to return 1

I've also changed its return type to uint32_t,
because this function is always used to set the value of uint32_t variables,
and because the index already has this type.

* llama : fix state size calculation

Some bytes in the state were unaccounted for in llama_get_state_size.
Since the logits reserve so much space, it did not cause problems.

You can also specify a *reverse prompt* with the parameter `-r "reverse prompt string"`.

 ### API like OAI
 
-API example using Python Flask: [api_like_OAI.py](api_like_OAI.py)
-This example must be used with server.cpp
-
-```sh
-python api_like_OAI.py
-```
-
-After running the API server, you can use it in Python by setting the API base URL.
-
-```python
-openai.api_base = "http://<Your api-server IP>:port"
-```
-
-Then you can utilize llama.cpp as an OpenAI's **chat.completion** or **text_completion** API

 ### Run @bug, @wip or @wrong_usage annotated scenario
 
 Feature or Scenario must be annotated with `@llama.cpp` to be included in the default scope.
+
 - `@bug` annotation aims to link a scenario with a GitHub issue.
 - `@wrong_usage` are meant to show user issue that are actually an expected behavior
 - `@wip` to focus on a scenario working in progress
+- `@slow` heavy test, disabled by default
 
 To run a scenario annotated with `@bug`, start:
-`DEBUG=ON ./tests.sh --no-skipped --tags bug`
+
+```shell
+DEBUG=ON ./tests.sh --no-skipped --tags bug
+```
 
 After changing logic in `steps.py`, ensure that `@bug` and `@wrong_usage` scenario are updated.
+
+```shell
+./tests.sh --no-skipped --tags bug,wrong_usage || echo "should failed but compile"
+```
