MDEV-26664 Store UUIDs in a more efficient manner

UUID values llllllll-mmmm-Vhhh-vsss-nnnnnnnnnnnn are now stored as nnnnnnnnnnnn-vsss-Vhhh-mmmm-llllllll inside the record: - the groups (segments separated by dash) are reordered right-to-left. - the bytes inside the groups are not reordered (stored as before, in big-endian format). This provides a better sorting order: the earlier UUID was generated, the higher it appears in the ORDER BY output. Also, this change enables a good key prefix compression, because the constant part is now in the beginning, while the non-constant part (the timestamp) is in the end.

   format and their own (variable size) canonical string representation.
 
   Examples are INET6 and UUID types.
+
+  The MariaDB server uses three binary representations of a data type:
+
+  1. In-memory binary representation (user visible)
+    This representation:
+    - can be used in INSERT..VALUES (X'AABBCC')
+    - can be used in WHERE conditions: WHERE c1=X'AABBCC'
+    - is returned by CAST(x AS BINARY(N))
+    - is returned by Field::val_native() and Item::val_native()
+
+  2. In-record binary representation (user invisible)
+    This representation:
+    - is used in records (is pointed by Field::ptr)
+    - must be comparable by memcmp()
+
+  3. Binlog binary (row) representation
+    Usually, for string data types the binlog representation
+    is based on the in-record representation with trailing byte compression:
+    - trailing space compression for text string data types
+    - trailing zero compression for binary string data types
+
+  We have to have separate in-memory and in-record representations
+  because we use HA_KEYTYPE_BINARY for indexing. The engine API
+  does not have a way to pass a comparison function as a parameter.
+
+  The default implementation below assumes that:
+  - the in-memory and in-record representations are equal
+  - the binlog representation is compatible with BINARY(N)
+  This is OK for simple data types, like INET6.
+
+  Data type implementations that need different representations
+  can override the default implementation (like e.g. UUID does).
