Currently, there are a number of compilation warnings from zlib like the
following one:
../deps/zlib/infback.c: In function ‘inflateBack’:
../deps/zlib/infback.c:479:25: warning:
this statement may fall through [-Wimplicit-fallthrough=]
479 | state->mode = LEN;
| ~~~~~~~~~~~~^~~~~
../deps/zlib/infback.c:481:9: note: here
481 | case LEN:
| ^~~~
In this case there is no break statement and the intention is to fall
through:
Tracev((stderr, "inflate: codes ok\n"));
state->mode = LEN;
case LEN:
This commit adds -Wno-implicit-fallthrough' to zlib.gyp to suppress
these warnings.

Fix the compile flags so that zlib can run on CPUs that do
not have SSSE3/SSE4.2/etc. Do not compile zlib with flags that
indicate that those features are available, and instead enable
them selectively for functions that use them.
There are probably better way to do this, e.g. through gyp file
modifications as suggested in the issue. However, this patch
should do just fine until that happens.

This define is not available in zlib prior to version 1.2.5.2. See
https://github.com/nodejs/node/issues/9110 for details. Workaround the
build breakage reported by casting away const in src/inspector_agent.cc
instead.

Build the bundled zlib with -DZ_HAVE_UNISTD_H to make the definition of
close(), read() and other unistd.h functions available to gzread.c and
gzwrite.c. It's kind of silly that we have to jump through hoops here
because we never call any of the functions that do I/O directly, but at
least it squelches the -Wimplicit-function-declaration warnings.
