When rotating a partially shown image (i.e. image size * zoom >
window size) the image is panned to top or left (if `win->w` or
`win->h` is greatest, respectively). Seems to be due to
unsignedness of `win->[wh]`, when taking the difference between
them in `img_rotate` either `img->[xy]` ends up being close to
`UINT_MAX` and the image is panned to top or left edge.

additionally this fixes a regression introduced by 3659361 where the

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.

4b67816 only partially fixed this issue. because imlib2's cache may not
have sub-second granularity, there still exists a time-frame while the
`mtime` has not yet been updated but we might be trying to reload the
image due to receiving an inotify event in which case imlib2 will end up
giving us the old frame.
imlib2 v1.12.0 adds a function that allows us to decache any frames
associated with a filename. this allows us to invalidate the cache
manually instead of relying on `mtime`.
but if that's not available due to older imlib2, then forcefully reload
the raw frames and decache them. this has the unfortunate cost that if
`mtime` *was* updated properly then we'll end up loading that image
twice.

currently the autoreload feature of nsxiv is a bit unreliable because we
try to load at the very first event we received. however, the writer
might not be done writing and so we might try to load a truncated image
(and fail).
in the following ascii diagram, function S represents sleep and `+` sign
represents writes by the writer. because we set the sleep (of 10ms) at
the first event, subsequent writes by the writer doesn't influence our
reload logic:
S(10) load()
nsxiv | |
writer + + + + (done)
time(ms): 00 05 10 15
after this patch, (assuming function T (re)sets a timeout), we will keep
(re)setting a timeout on new events giving the writer more time to
finish:
T(10) T(10) T(10) T(10) load()
nsxiv | | | | |
writer + + + + (done)
time(ms): 00 05 10 15 20 25
while this patch makes things significantly more robust, the problem
here is inherently unsolvable since there's no way to tell whether the
writer is done writing or not.
for example, if user does something like `curl 'some.png' > test.png`
then curl might stop for a second or two in the middle of writing due to
internet issues - which will make nsxiv drop the image.
this patch also increases the autoreload delay from 10ms to now 128ms
instead to decrease chances of false failures.

1. `c99` doesn't exist on openbsd
2. `c99` behaves weirdly on macos (doesn't support -Wall)

aside from giving the user information about the feature set the binary

* switch to git ls-files to avoid picking up any other local .c files
* enable assertions during static analysis since we used some assertions to
disable/silence certain warnings.
* update TCC commit hash to a more recent one
* parallelize static analysis
cppcheck already has -j argument to parallelize it's analysis and
provide results faster, clang-tidy unfortunately doesn't.
so use xargs -P to archive parallel execution. on my system this brings
down the analysis time from ~27s to ~5s.

the fedora copr repo is no longer being updated since the maintainer of
it, mamg22, no longer uses nsxiv in his daily setup (and thus stopped
contributing to nsxiv as well).
he has requested the repo and his email to be removed from the project.
so go ahead and honor that request.

slight addendum to 657080a7e55843e351fa6ce41e4ce315eab62b67
instead of disabling asserts by adding -DNDEBUG to config.mk, this
disables asserts by default in the source code itself. this way, if
someone compiles with `make CFLAGS="-O3 -march=native"` without knowing
about asserts/-DNDEBUG then he won't accidentally get a build with
assertions in it.
this basically makes the assertions opt-in, if someone wants it, he'll
need to *explicitly* set `-DDEBUG` to get it. so that it's not possible
to accidentally end up with assertions enabled.

gif spec [0] doesn't mention what to do when "Delay Time" is 0.
apng spec [1] states:
| If the the value of the numerator is 0 the decoder should render the
| next frame as quickly as possible, though viewers may impose a
| reasonable lower bound.
webp spec [2]:
| the interpretation of frame duration of 0 (and often <= 10) is
| implementation defined.
so it seems that it's safe to set a default delay for 0 delay frames,
which is what the older gif and webp loaders were already doing. do the
same for the imlib2 multi-frame loader as well.

by default imlib2 doesn't check the file's timestamp to avoid disk
activity when loading from cache. however, this ends up breaking our
autoreload functionality on multi-frame images.
the reason why single frame images weren't broken was because
`img_load()` calls `imlib_image_set_changes_on_disk()`, which tells
imlib2 to check the timestamp before loading from cache.
do the same thing for the multi-frame loader as well.
additionally add a comment to img_load() explaining what's going on.

clang-tidy currently flags the following:
util.c:57:8: error: 'ptr' may be set to null if 'realloc' fails, which may result in a leak of the original buffer [bugprone-suspicious-realloc-usage,-warnings-as-errors]
ptr = realloc(ptr, size);
the analysis here is correct, but if realloc fails, we simply exit so
there's no real "leak".
moreover this check is not very useful for nsxiv's codebase because we
do not use naked realloc(), instead we use the erealloc wrapper that
exits on failure. so just disable the warning entirely instead of
changing the source code to silence the false positive.

assertions are for debugging purposes, and so shouldn't be enabled for
"release" builds. disable it by default by using `-DNDEBUG`.
`-O2` on gcc/clang will result it slightly better binary. on tcc it'll
be ignored. and since -O is specified by POSIX there shouldn't be any
portability concern.
additionally add a (commented out) recommended debug build for gcc/clang
with address and undefined sanitizers turned on.

The last time[0] this was discussed, no-one was against it but no-one
was confident in it either and so it was added to nsxiv-extra as a
patch.
But now that enough time has passed, it seems like there's a pretty high
demand for something like this because there's plenty of use-cases that
use nsxiv as a "picker" where it's meant to quickly pick a single file.
And so add this as a convenient default key-bind.
