memdisk: handle recursive INT 13h invocation
Some systems, e.g. a lot of Thinkpads, invoke INT 13h recursively from
within the stack itself. This is generally a bad idea as it re-runs
any INT 13h hooks (including the ones that DOS installs!), but it
should work. Keep a counter of recursive invocations and simply
bypass the whole system including the DL shift if the invocation is
recursive.
With this, MS-DOS boots on a Thinkpad T61. FreeDOS is still broken,
though, but apparently in a different manner...

Instead of looking for a string of null bytes at the end of the OACK

packet, or we are hopelessly confused about how to make sense of the
rest of the packet -- in either case, ignoring is the "liberal"
option.

PXELINUX: handle OACK packets with extra NULs, cleaner TFTP error
There are apparently TFTP servers in the field which will send OACK
packets with extra NUL bytes appended at the end. If we find an OACK
packet where the only thing left at some point during processing is
NULs, then just consider the packet processed.
We have reported all TFTP protocol errors as "tsize required", which
is definitely not true anymore. Change error code to 0 (undefined)
and the error string to "TFTP error". When this code gets converted
to C we'll do better.
