The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.

In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.

When building u-boot as 64 bit application (e.g. sandbox) ulong might be
64 bits in size. This breaks network code as IPaddr_t is 64 bytes in
size then and an IPv4 address is 32 bits in size. This patch makes sure
that IPaddr_t is always 32 bits in size. Also some warnings introduced
by this patch are fixed.

This is long over due.  All but two net drivers have been converted, but
those have now been dropped.

The only thing left to do is actually delete all references to NET_MULTI

So far, TFTP negotiated a fixed retransmission timeout of 5 seconds.
In some cases (busy networks, slow TFTP servers) this caused very
slow transfers. A new environment variable "tftptimeout" allows to
set this timeout. Lowering this value may make downloads succeed
faster in networks with high packet loss rates or with unreliable
TFTP servers.

Optionally add RFC 2349 "Transfer Size Option", so we can minimize the
time spent sending data over the UART (now print a single line during a
tftp transfer).

 - If turned on (CONFIG_TFTP_TSIZE), U-Boot asks for the size of the file.
 - if receives the file size, a single line (50 chars) are printed.
     one hash mark == 2% of the file downloaded.
 - if it doesn't receive the file size (the server doesn't support RFC
     2349, prints standard hash marks (one mark for each UDP frame).

Increasing the block size is useful if CONFIG_IP_DEFRAG is
used. Howerver, the last fragments in a burst may overflow the
receiving ethernet, so the default is left at 1468, with thre new
CONFIG_TFTP_BLOCKSIZE for config files. Further, "tftpblocksize"
can be set in the environment.

The TftpStart() function modifies the 'BootFile'
string when 'BootFile' contains both an IP address
and filename (eg 1.2.3.4:/path/file). This causes
subsequent calls to TftpStart to incorrectly parse
the TFTP filename and server IP address to use.
For example:

Speed: 100, half duplex

TFTP from server 10.52.0.62; our IP address is 10.52.253.79
