stdint.h is not as portable as inttypes.h. It doesn't exist at least
on AIX 5.1 and Solaris 7, while inttypes.h is present there and does
include stdint.h on platforms supporting it.
This is equivalent to libslz upstream commit e36710a ("slz: use
inttypes.h instead of stdint.h")
As we now embed the library we don't need to support the older 1.0 API
any more, so we can remove the explicit calls to slz_make_crc_table()
and slz_prepare_dist_table().
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).
See discussions below:

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.
