The zstate.hist_bits is an option and shouldn't be set randomly by a
deflate stateless run but like level we may set anyway.

The relic slver is no longer used for individual versioning
on functions and is confusing tools looking for data in text
sections. This removes all instances instead of fixing since
its usefulness is waining. Fixes#221

The goal of this patch is to make isa-l testsuite pass on s390 with
minimal changes to the library. The one and only reason isa-l does not
work on s390 at the moment is that s390 is big-endian, and isa-l
assumes little-endian at a lot of places.
There are two flavors of this: loading/storing integers from/to
memory, and overlapping structs. Loads/stores are already helpfully
wrapped by unaligned.h header, so replace the functions there with
endianness-aware variants. Solve struct member overlap by reversing
their order on big-endian.
Also, fix a couple of usages of uninitialized memory in the testsuite
(found with MemorySanitizer).
Fixes s390x part of #188.

Instead of using a constant as default zlib header, create the header on the fly. Both zlib
header bytes depend on the wbits and compression level used.
Make sure that ISA-L compression level 0 is advertised as the fastest compression in
both the gzip header (setting xfl flag to 0x04) and the zlib header (as 0, fastest, other levels are 1, fast).

In the newly added function isal_deflate_process_dict(), a null check
was added to the dictionary struct but was ineffectual because of the
order.

Fixes invalid logic that attempted to eliminate unnecessary copy of input to the
history buffer in cases where it is not required. Correction should improve
performance and not change functionality.

This was replaced with detect_repeated_char_length(), but the

compression which is the same algorithm as level 1 but with a larger
