Alfred Wingate d95b678d7a server: Remove undeclared variable from tracing macro
* 3647457f6d accidentally referred to
  an nonexistant variable. This leads to build failure if you then
  enable the systemtap feature.
* Downstream bug https://bugs.gentoo.org/902141

Andri Yngvason c22a0c0379 Add option to enable experimental features
With this, I can release without modifying things specially on the release
branch.

Andri Yngvason dedac2f82f Implement colour map
Instead of dropping the connection, we now implement a simple static
colour map that emulates RGB332.

The quality isn't great, but it's better than dropping the connection
without any explanation.

Andri Yngvason 9fa1027353 server: Drop current frame if formats change
If the currently in-flight frame was dispatched before a format change,
it might be the wrong format for the client, so it's better to drop it.

Andri Yngvason c7d7929f7c Keep zlib streams when switching encodings
Both RealVNC and TigerVNC clients expect zlib streams to remain when
switching encodings, so when they switch back, inflate fails if the
encoder is discared.

fixes #109

Andri Yngvason c76129b2d2 server: Remove DNS lookup
DNS lookup is slow and can even fail. Under some circumstances, it will
even block for a significant amount of time until it completes.

The user of this library can do the lookup instead if they wish.
