we skip it in check_if_legal_tablename.

A map for faster reserved_names lookup,

helps to avoid loops in many cases.

Check if a table name may cause problems

102
name Table name (without any extensions)
105
We don't check 'CLOCK$' because dollar sign is encoded as @0024,
106
making table file name 'CLOCK@0024', which is safe.
107
This is why we start lookup from the second element
108
(i.e. &reserver_name[1])
