When large buffers have been opened, copying Kakoune's memory
page descriptors can get pretty slow, making fork more expensive
than necessary.
vfork avoids that problem. While not strictly conforming, it seems
the few calls we do before execve (open, close, dup2 and
set_signal_handler) would not cause any problems on platforms we
care about.

the buffer name was not a very interesting information, whereas
the buffer range allows a hook to run only on the appended text
instead of all the buffer.
m_last_setup was not storing the actual position that was used to
redraw the window, but the previous one, leading to an additional
spurious redraw immediatly after (triggered by window position not
believed to be the one at last redraw).

This highlighting and static completion for types and macros that were
previously missing. No functions are included, but some macros are
highlighted as such, even if they're function-like macros.
As we do at most one push_next per step_thread, and we pop_current
before step_thread, we can avoid a branch there at the expense of
sometimes growing unecessarily (once).
