3573fcca80 design_utils: Set port.net to null when disconnecting 
Without this the python bindings can't actually connect anything else
to a disconnected port since the assert in connect_ports will think
it's still connected

ec1eea9990 Fix assertion failure on invalid LOCATE input. 
Trying to parse this invalid LPF syntax:

    LOCATE COMP "a" SITE "A1"
    IOBUF PORT "a" IO_TYPE=LVCMOS33;

(note missing semicolon on first line) gives an assertion failure in
strip_quotes, because the fifth token is scanned as "A1"IOBUF (without
a trailing quote).

Avoid the problem by detecting extraneous input and issuing a more
specific error.

8cc6a2fae5 Remove comment about the USRMCLK primitive being untested. 
Tested and verified working: the trivial configuration:

    module USRMCLK( USRMCLKI, USRMCLKTS );
        input USRMCLKI, USRMCLKTS;
    endmodule

    module top( input clk );
        reg[ 24:0 ] count = 0;

        always @( posedge clk ) begin
            count <= count + 1'b1;
        end

        USRMCLK mspi( .USRMCLKI( count[ 20 ] ), .USRMCLKTS( count[ 24 ] ) );
    endmodule

produces the expected output (toggling at high frequency, toggling
tri-state at lower frequency) on an LFE5U-85 when fed with an appropriate
clock.  See https://bayimg.com/AAnNKAAGO for an example.  The top
(magenta) trace is the MCLK line.
