Use zlib to gzip-compress uploads 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.

Description:
“A massively spiffy yet delicately unobtrusive compression library.”
zlib is a free, general-purpose, legally unencumbered lossless data-compression
library. zlib implements the “deflate” compression algorithm described by RFC
1951, which combines the LZ77 (Lempel-Ziv) algorithm with Huffman coding. zlib
also implements the zlib (RFC 1950) and gzip (RFC 1952) wrapper formats.
Local Modifications:
See zlib/README.chromium.
