Converted the build system to caktin

add option to not use clang so i can use this in bitbake

Adding baudrates: 1000000, 11520000, 2000000, 2500000, 3000000, 3500000, and 4000000 to the unix.cc implementation. This is an attempting to work around issue #18, needs testing on a non-USB serial adapter that can handle higher baudrates.

Clean up of the build system.  Added rt and util in certain places so compiling the tests on Linux succeed, which should fix #19.  Also removed over verbose warnings on Linux when build stand-alone.

Fixing a bug in the unix write code which may have prevented it from writing in some cases, and updating some of the comments and error messages in the write function that still read like the read function
