[PATCH] kvmtool/term: unexport term_set_tty, term_init, term_exit

[Oleg Nesterov]

According to git grep they can be static.

term_got_escape can be static too, and we can even move it into
term_getc().

"int term_escape_char" doesn't make sense at least until we allow
to redefine it, turn it into preprocessor constant.
