[xilinxc]: Fixed some warnings. Added time measurement to Compiler class.
[xilinxc]: Added xilinx_synthesizer_time and xilinx_adaptive_time to the configuration. Not yet fully supported.
[xilinxc]: Adaptive timing should now work for both synthesizing and programming
[xilinxc]: Modified several instances of 'compiling' for 'synthesizing', in both client and server sides, including in internal commands etc.
[xilinxc]: Added client-side support (hence, full support now) for expectedSynthesizingTime
