Compare two keys
SYNOPSIS
_mi_key_cmp()
keyseg Key segments of key to compare
a First key to compare, in format from _mi_pack_key()
This is normally key specified by user
b Second key to compare. This is always from a row
key_length Length of key to compare. This can be shorter than
a to just compare sub keys
next_flag How keys should be compared
If bit SEARCH_FIND is not set the keys includes the row
position and this should also be compared
NOTES
Number-keys can't be splited
RETURN VALUES
<0 If a < b
0 If a == b
>0 If a > b
