void ** does not exist: the address of a generic pointer is not
properly defined (different pointer types may have different
representations). So, alloc_realloc cannot exist as is without UB.
Fortunately, it's not supposed to be used in the skalibs programming
style, and skalibs itself only uses it in two places
(stralloc_ready_tuned and stralloc_shrink) where the pointer is a
char *.
So we just fix the UB by making alloc_realloc() take a char **,
and it's only defined for that pointer type.
Nothing to see here folks, nothing happened at all.
We're down to ONE rogue sysdep, boys.

libdatastruct still missing, library still not functional
add arc4random_addrandom sysdep; next batch of types changes.2017-02-15T17:40:40ZLaurent Bercotska-skaware@skarnet.org2017-02-15T17:40:40Zurn:sha1:a896ca2a8c617e5e00ffd5fc9e69331ad754e5b3
The library isn't supposed to be functional yet: there are
still a lot of type mismatches.
