The rarp code includes another instance of the auto_load logic, so call
what is now net_auto_load() instead.
This also fixes an incorrect call to TftpStart() which was never seen
since apparently no boards enable rarp.

Commit 093498669 (Put common autoload code into auto_load() function)
broke handling of autoload environment variable not being set.
The bootp/dhcp code will just keep on requesting IP address forever
and never start TFTP download.
Fix it by moving TftpStart() outside the conditional like it was before.

Minor ./net cleanups - no functional changes
- change #ifdef DEBUG printf(); #endif to just debug()
- changed __FUNCTION__ to __func__
- got rid of extra whitespace between function and opening brace
- removed unnecessary braces on if statements
gcc dead code elimination should make this functionally/size equivalent
when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3).

The problem is that BOOTP_SIZE uses ETHER_HDR_SIZE which is 14 bytes.
If sending a VLAN tagged frame (when env variable vlan is set) this

Enforce millisecond semantics of the first argument to NetSetTimeout() --
the change is transparent for well-behaving boards (CFG_HZ == 1000 and
get_timer() countiing in milliseconds).
Rationale for this patch is to enable millisecond granularity for
network-related timeouts, which is needed for the upcoming automatic
software update feature.
Summary of changes:
- do not scale the first argument to NetSetTimeout() by CFG_HZ
- change timeout values used in the networking code to milliseconds

Found a bug in the way the DHCP Request packet is built, where the IP address
that is offered by the server is bound to prematurely. This patch is a fix of
that bug where the IP address offered by the DHCP server is not used until
after the DHCP ACK from the server is received.
