Drop assert in zrealloc and raise runtime error

Most assert in code are useful because they signal a real bug. However,
if allocation on the heap fails, it is a runtime error because system
gets rid of memory. This is more important on embedded systems,
and the caller process cannot exit but it should be informed with return
code and it will decide how to work on.

This drop the assert clause and add error code handling when zrealloc is
called. Because realloc does not touch the original pointer if fails, it
frees memory to avoid leaks.

Add a way to disable check of chunk min size

The check for chunk size is done on the compressed data.
This forbids to create the same chunk set in case data is not compressed
and comparison is done using the hashes of original data and not of
compressed chunk.
