[En-Nut-Discussion] Bugfixes from today

[Oliver Schulz]

Hello all,

I just commited some bugfixes to nut-3_4-release and HEAD into CVS:

* net/tcpsm.c: Bugfix in several tcp state functions. Swapped around the
  check for ACK and SYN flag. Because initial SYN packets don't have an
  ACK flag, recevied SYN packets were never rejected.
  This bug was discovered by Damian Slee. It seems, that tcp stack is now
more reliable. Heavily stressed httpd application doesn't loose tcp sockets
any more.

* pro/resolv.c: Memory leak fixed in CreateDnsQuestion.
  Bugfix by Jean Pierre Gauthier. On re-creating the structure for dns
question, some previously allocated memory was not released.

* crt/getf.c: Several bugfixes from Francois Rademeyer applied.
 - "%%" didn't work.
 - integer parsing corrected.
 - support for "%u".


Many thanks to all the authors and testers, who help us to build a reliable
Nut/OS!!!

Cheers,
Oliver.
