lib/alloc/realloc*.h: Always reallocate at least 1 byte
...
glibc's realloc(3) is broken. It was originally good (I believe) until
at some point, when it was changed to conform to C89, which had a bogus
specification that required that it returns NULL. C99 fixed the mistake
from C89, and so glibc's realloc(3) is non-conforming to
C99/C11/POSIX.1-2008. C17 broke again the definition of realloc(3).
