Refactoring resizing into state machine.

- Fixes MSTSC resizing (with RFX as well).
- Queue system so that resizes are processed when XRDP and the X server
are ready, not immediately.
- Deletes and recreates the encoder (RFX fix)
- Introduces a dynamic_monitor_description struct that is used for the
queue system.
- Fix some lines previously introduced by the original resizing code to
be 80 chars long, as is the standard for XRDP.
