to reproduce:
( unset HOME XDG_CACHE_HOME; nsxiv -t ~/pictures; )
the code never really worked without a cache_dir going back to
original sxiv. so just fatally error out instead of crashing
with a null pointer dereference.
by writing to a tmpfile first, and then renaming it to the desired
target - multiple nsxiv instances writing thumbnail at the same time are
guaranteed not to stomp over one another.
rename() is guaranteed to be atomic by POSIX. however, it can fail with
EXDEV if both the files don't reside in the same filesystem. and so we
cannot make the tmpfile something like "/tmp/nsxiv-XXXXXX".
instead, create the tmpfile inside the cache_dir to reduce chances of
EXDEV occuring.
currently the logic of when to open/close script is scattered around the
entire code-base which is both ugly and error-prone.
this patch centralizes script handling by remembering the relevant
information on each redraw and then comparing it with the previous
information to figure out whether something changed or not.
this also fixes a bug where scripts weren't being called in thumbnail
mode when mouse was used for selecting a different image.

instead of silently ignoring bogus arguments (i.e programming errors),
which can make debugging harder, it's better to assert them so that they
get caught faster in debug builds.

mixing signed and unsigned types in comparison can end up having
unintended results. for example:
if (-1 < 1U)
printf("true\n");
else
printf("false\n");
previously we silenced these warnings, instead just fix them properly
via necessary casting, and in cases where the value cannot be negative
(e.g width/height members) make them unsigned.

currently, in case of error, r_mkdir will leave the path at a truncated
state.
a7d39b0ab8 is the commit that introduced this change, and in it the
error printing is moved from r_mkdir to the caller, which makes me think
it was probably intentional.
make it so that the function itself prints the error/warning
message and returns the path back to the caller unharmed.

the goal here to mark functions and variables not used outside the
translation unit as static. main reason for this is cleanliness. however
as a side-effect this can help compilers optimize better as it now has
guarantee that a certain function won't be called outside of that
translation unit.
one other side-effect of this is that accessing these vars/function from
config.h is now different.
if one wants to access a static var/func from different translation unit
in config.h, he would have to create a wrapper function under the right
ifdef. for static functions one would also need to forward declare it.
here's a dummy example of accessing the function `run_key_handler` from
config.h under _MAPPINGS_CONFIG
```
static void run_key_handler(const char *, unsigned);
bool send_with_ctrl(arg_t key) {
run_key_handler(XKeysymToString(key), ControlMask);
return false;
}

visual glitch. The values `.color.red` on the other hand and so on are always
integers between 0 and 0xFFFF representing the color as expected.

if im is NULL we're going to load it with imlib2 anyways.
one other problem this solves is that before, due to the fatal error,
