This adds zlib to Crashpad. By default in standalone Crashpad builds, the system zlib will be used where available. A copy of Chromium’s zlib (currently a slightly patched 1.2.11) is checked out via DEPS into third_party for use on Windows, which does not have a system zlib. zlib is used to produce gzip streams for HTTP upload request bodies sent by crashpad_handler by default. The Content-Encoding: gzip header is set for these compressed request bodies. Compression can be disabled for upload to servers without corresponding decompression support by starting crashpad_handler with the --no-upload-gzip option. Most minidumps compress quite well with zlib. A size reduction of 90% is not uncommon.
