When compressing, the output / input is a binary format, not a text
format like BASE64.  This is important on Windows, where a ^Z in a
text file is seen as EOF, and there could be a ^Z somewhere in a
compressed file, cutting it short as input.

Instead of absolute hard coding of the libz library name, have it use
the macro LIBZ, which is set to defaults we know in case it's
undefined.

This allows our configuration to set something that's sane on current
or older platforms, and allows the user to override it by defining
LIBZ themselves.

The macros ZLIB and ZLIB_SHARED weren't appropriately defined,
deviating wrongly from how they worked in earlier OpenSSL versions.
So, restore it so that ZLIB is defined if configured "enable-zlib" and
so that ZLIB and ZLIB_SHARED are defined if configured
"enable-zlib-dynamic".

Additionally, correct the interpretation of the --with-zlib-lib value
on Windows and VMS, where it's used to indicate the actual zlib
zlib library file / logical name, as that can differ depending on zlib
version and packaging on those platforms.

Finally for Windows and VMS, we also define the macro LIBZ with that
file name / logical name when configured "zlib-dynamic", so the
compression unit can pick it up and use it.

There is a preference for suffixes to indicate that a function is internal
rather than prefixes. Note: the suffix is only required to disambiguate
internal functions and public symbols with the same name (but different

Code without PEDANTIC has intentional "undefined" behaviour. To get best
coverage for both PEDANTIC and non-PEDANTIC codepaths, run the sanitizer
builds in two different configurations:
1) Without PEDANTIC but with alignment checks disabled.
2) With PEDANTIC.

To not overload Travis too much, run one build with clang and the other
with gcc (chosen at random).

Also remove a micro-optimization in CAST code to be able to
-fsanitize=shift. Whether shift sanitization is meaningful for crypto or
an obstacle is debatable but since this appears to be the only offender,
we might as well keep the check for now.
