uml: console subsystem tidying
This does a lot of cleanup on the UML console system. This patch should be
entirely non-functional.
The tidying is as follows:
header cleanups - the includes should be closer to minimal and complete
all printks now have a severity
lots of style fixes
fd_close is restructured a little in order to reduce the nesting
some functions were calling the os_* wrappers when they can
call libc directly
port_accept had a unnecessary variable
it also tested a pid unecessarily before killing it
some functions were made static
xterm_free is gone, as it was identical to generic_free
