Some include files, mostly types definitions, are missing a few includes
to define the types they're using, causing include ordering dependencies
between files, which are most often not seen due to the alphabetical
order of includes. Let's just fix them.
These were spotted by building pre-compiled headers for all these files
to .h.gch.
When the code is preprocessed first and compiled later, such as when
built under distcc, the "fall through" comments are dropped and warnings
are emitted. Let's use the alternative "fallthrough" attribute instead,
that is supported by versions of gcc and clang that also produce this
warning.
This is libslz upstream commit 0fdf8ae218f3ecb0b7f22afd1a6b35a4f94053e2
On ARM with native CRC support, no need to inflate the executable with
a 4kB CRC table, let's just drop it.
This is slz upstream commit d8715db20b2968d1f3012a734021c0978758f911.
SLZ is rarely packaged by distros and there have been complaints about
the CPU and memory usage of ZLIB, leading to some suggestions to better
address the issue by simply integrating SLZ into the tree (just 3 files).

This patch does just this, after minor adjustments to these files:
- tables.h was renamed to slz-tables.h
- tables.h had the precomputed tables removed since not used here
- slz.c uses includes <import/slz*> instead of "slz*.h"
The slz commit imported here was b06c172 ("slz: avoid a build warning
with -Wimplicit-fallthrough"). No other change was performed either to
SLZ nor to haproxy at this point so that this operation may be replicated
if needed for a future version.
