NRK fb5b2e5e64 icons-hash: fix bitwise rotation 
in case the rotation is 0, `v >> (32 - r)` would end up doing a 32 right
shift which is equal to the width of `v` and thus undefined behavior.

icons-hash: misc improvements (#1553) 
* icons-hash: take total probe count into account as well

* icons-hash: use a better PRNG

the older method was using a multiplicative congruential generator (MCG)
which doesn't work too well especially with just 32 bits of state.

change it to a PCG instead with 64 bits of state (and 32 bits of output)
which should give better results.

and since we should get better rng - the search iteration has been
halved as well to save some build time.

* icons-hash: use an xor-rotate hash function

* icons-hash: fix some compiler warnings

NRK 29a5992dee use standard C11 alignas 
nnn source code already uses C11, which introduced `_Alignas` [^0] as a
standardized alternative to __attribute__((aligned)).

there are no other usage of `__attribute__` in the nnn source code, so
in theory this should make things more portable across compilers.

also removes an unnecessary usage of `alloca()` with an aligned constant
sized buffer instead.

Improved chunk allocation logic 
Found memory deallocation edge case

Update and move chunk limit check

Generalize maximum size of input

Remove hard-coded values

Remove superfluous check before free

Let the kernel deal with extra data

Handle signals while reading

Conform to the manpage

Make CI happy

use `size_t` instead of `ssize_t`

`ssize_t` was used just so `--i` when `i` was zero would become -1
instead of SIZE_MAX. for looping through something in reverse order, the
"goes-to" operator (`-->`) can be used instead which doesn't require `i`
to be signed anymore.

remove useless blank line

use a normal loop

don't see any reason why freeing in reverse order would've been needed.

NRK fe9c1bbb3a icons: use a compact array 
a lot of the extension use the same icon. this can be exploited via
having an array with all the unique icons and then storing a single byte
index into the unique array.

when using `O_EMOJI` this results in around ~1.7KiB drop in the total
table size. `O_NERD` and `O_ICONS` get roughly ~0.5KiB savings.
