printf() -> printh()
Merge branch 'proto2' of https://github.com/kesl/khypervisor into kesl-proto2
add printh function. include stdio.h and use that funtion.
format.c calls printh, and need not know uart's function.
merge proto2 with printf supported proto2
Include print.h, then can use printh(). do not need modify uart_print.c
remove stdio.c stdio.h instead add print.c print.h
remove puts() and putc() move format_puts and format_putc into format.c and make them static (not visible to outside of format.c)
puts_t -> format_puts_t putc_t -> format_putc_t
