Move it away from http2 to generic core crate.
And use it for DCERPC (and SMB)
And remove the C version.
Main change in API is the free function is not free itself, but
a rust wrapper around unbox.
Ticket: #4112
So that we do not have an endless loop casting index to
u16 and having more than 65536 buffers in one transaction
Changes for all protocols, even ones where it is impossible
to have such a pattern, so as to avoid bad pattern copy/paste
in the future
Fix multi inspect buffer API causing cleanup logic in the single
inspect buffer paths. This could lead to a buffer overrun in the
"to clear" logic.
Multi buffers now use InspectionBufferSetupMulti instead of
InspectionBuffer. This is enforced by a check in debug validation.
Simplify the multi inspect buffer setup code and update the callers.
In some cases, the InspectionBufferGet function would be followed by
a failure to set the buffer up, for example due to a HTTP body limit
not yet being reached. Yet each call to InspectionBufferGet would lead
to the matching list_id to be added to the
DetectEngineThreadCtx::inspect.to_clear_queue. This array is sized to
add each list only once, but in this case the same id could be added
multiple times, potentially overflowing the array.
