OPTIONAL
SYNOPSIS
        string * db_coldefs(int handle)

DESCRIPTION
        Return an array with the column names of the current table.
        If the database didn't return a result, the result of this efun
        is 0.

        The function is available only if the driver is compiled with
        mySQL support. In that case, __MYSQL__ is defined.

        The efun triggers a privilege violation ("mysql", "db_coldefs").

HISTORY
        Added in 3.2.9.
        LDMud 3.2.11 added the privilege violation.
