code-style: simplify some checks
main change here is making the `zoom()` logic saner. the rest of the
changes are just small stuff which accumulated on my local branch.
pop() must not be called with NULL. and `zoom()` achieves this, but in a
very (unnecessarily) complicated way:
if c == NULL then nexttiled() will return NULL as well, so we enter this
branch:
if (c == nexttiled(selmon->clients))
in here the !c check fails and the function returns before calling pop()
if (!c || !(c = nexttiled(c->next)))
return;
however, none of this was needed. we can simply return early if c was NULL.
Also `c` is set to `selmon->sel` so we can use `c` in the first check
instead which makes things shorter.

When monitors are removed, the coordinates of existing monitors may
change, if the removed monitors had smaller coordinates than the
remaining ones.
Remove special case handling so that the same update-if-necessary loop
is run also in the case when monitors are removed.

In certain instances trans may be set to a window that doesn't actually
map to a client via wintoclient; in this case it doesn't make sense
to set isfloating/oldstate since trans is essentially invalid in that
case / correlates to the above condition check where trans is set /
XGetTransientForHint is called.

mechanism from SIGUSR1 to SIGRTMIN which is likely to cause issues for
those that already have a working setup. A compatibility option has been
added which changes this back to SIGUSR1. Note that configuration was
also changed.
This was ref. reported issue #114.
