Apply heuristics to avoid breaking users existing configurations with the change to not always add the default sequences. If we find a cache that was generated before 4.4, and the Compose file does not have an include, and doesn't contain so many sequences that it is probably a copy of the system one, we take steps to keep things working, and thell the user about it.

|
|
* The first part of the data contains rows of length max_seq_len + 1,
|
|
* where the first element is the item of the sequence, and the
|
|
* following elements are offsets to the data for sequences that

|
* start with the first item of length 2, ..., max_seq_len.
|
|
*
|
|
* The second part of the data contains the rest of the sequence
|
|
* data. It does not have a fixed stride. For each sequence, we
|
|
* put seq[2], ..., seq[len - 1], followed by the encoded value
|
|
* for this sequence.
|
|
*
|
|
* The values are encoded as follows:
|
|
*
|
|
* If the value is a single Unicode character smaler than 0x8000,
|
|
* then we place it directly. Otherwise, we put the UTF8-encoded
|
|
* value in the char_data array, and use offset | 0x8000 as the

|
* encoded value.
