DHCP request fix for Windows Server 2003
Added option CONFIG_BOOTP_DHCP_REQUEST_DELAY. This provides an optional
delay before sending "DHCP Request" in net/bootp.c. Required to overcome
interoperability problems with Windows Server 200x DHCP server when U-Boot
client responds too fast for server to handle.
