Quote a table name so it can be used in "SHOW TABLES LIKE <tabname>"
SYNOPSIS
quote_for_like
name - name of the table
buff - quoted name of the table
DESCRIPTION
Quote \, _, ' and % characters
Note: Because MySQL uses the C escape syntax in strings
(for example, '\n' to represent newline), you must double
any '\' that you use in your LIKE strings. For example, to
search for '\n', specify it as '\\n'. To search for '\', specify
it as '\\\\' (the backslashes are stripped once by the parser
and another time when the pattern match is done, leaving a
single backslash to be matched).
Example: "t\1" => "t\\\\1"
