0.49test1 testing release

[Matt Johnston]

Hi all.

I've put a prerelease tarball of Dropbear 0.49 at
http://matt.ucc.asn.au/dropbear/testing/dropbear-0.49test1.tar.gz

It's probably right to be 0.49, however there are some
intrusive changes to channel handling in particular that
could do with some wider testing. I'd appreciate if anyone
could let me know of problems they have.

As long as there aren't any significant problems that
version will probably become 0.49 in about a week. The
changelog follows.

Cheers,
Matt

0.49test1 - Mon 12 February 2007

- Compile fixes, make sure that all variable definitions are at the start
  of a scope.

- Added -P pidfile argument to the server (from Swen Schillig)

- Add -N dbclient option for "no command"

- Add -f dbclient option for "background after auth"

- Try to finally fix ss_family compilation problems (for old
  glibc systems)

- Fix finding relative-path server hostkeys when running daemonized

- Use $HOME in preference to that from /etc/passwd, so that
  dbclient can still work on broken systems.

- Fix various issues found by Klocwork defect analysis, mostly memory leaks
  and error-handling. Thanks to Klocwork for their service.

- Improve building in a separate directory

- Add compile-time LOG_COMMANDS option to log user commands

- Add '-y' flag to dbclient to unconditionally accept host keys,
  patch from Luciano Miguel Ferreira Rocha

- Return immediately for "sleep 10 & echo foo", rather than waiting
  for the sleep to return (pointed out by Rob Landley).
  
- Avoid hanging after exit in certain cases (such as scp)

- Various minor fixes, in particular various leaks reported by
  Erik Hovland
  
- Disable core dumps on startup

- Don't erase over every single buffer, since it was a bottleneck.
  On systems where it really matters, encrypted swap should be utilised.

- Read /dev/[u]random only once at startup to conserve kernel entropy

- Upgrade to LibTomCrypt 1.16 and LibTomMath 0.40

- Upgrade config.status and config.guess
