The auth methods that employ Getcredential() will only be used if the client's
GetCredential callback is actually set.

For backwards-compatibility reasons, we can only add struct members to the
end. That way, existing callers still can use newer libraries, as the
structs are always allocated by the library (and therefore guaranteed to
have the correct size) and still rely on the same position of the parts
the callers know about.

We do VNC but no RDP. Pointed out by Vic Lee, thanks!

Also put all helper scripts into a utils directory.

My bad. There we see what the encodings test is good for ;-)

* Fixed segfault on shutdown.
* Updated to test all encodings.
* Fixed to operate with encodings that split up rects into
  smaller rects.

There can not be more than 255 security types and MSLogon is
RFB 3.6 only.

This fixes a segfault when a server is invoked with the
'-help' commandline argument.

GnuTLS seems to expect proper errno values internally. So set them in our
custom push/pull functions. Parts of the patch stolen from libcurl, thanks!

Winsock does NOT update errno for us, we have fetch the last error
manually using WSAGetLastError().

According to the minilzo README, this brings a significant
speedup on 64-bit architechtures.

This adds generic before/after encoding buffers to the rfbClient
struct, so there is no need for thread local storage.

We have a git repo nowadays and I guess we won't go back to CVS.

If people seriously consider building with Visual Studio, there is
always CMake.

No functional changes. All files used by _both_ libvncserver and
libvncclient are put into a 'common' directory and references
from other files as well as Autotools and CMake build systems are
updated.
