+/*
+  Converts a string into its sort key.
+  
+  SYNOPSIS
+     my_strnxfrm_xxx()
+     
+  IMPLEMENTATION
+     
+     The my_strxfrm_xxx() function transforms a string pointed to by
+     'src' with length 'srclen' according to the charset+collation 
+     pair 'cs' and copies the result key into 'dest'.
+     
+     Comparing two strings using memcmp() after my_strnxfrm_xxx()
+     is equal to comparing two original strings with my_strnncollsp_xxx().
+     
+     Not more than 'dstlen' bytes are written into 'dst'.
+     To garantee that the whole string is transformed, 'dstlen' must be
+     at least srclen*cs->strnxfrm_multiply bytes long. Otherwise,
+     consequent memcmp() may return a non-accurate result.
+     
+     If the source string is too short to fill whole 'dstlen' bytes,
+     then the 'dest' string is padded up to 'dstlen', ensuring that:
+     
+       "a"  == "a "
+       "a\0" < "a"
+       "a\0" < "a "
+
