There are a lot of changes in this first phase, because there was a
lot of infrastructure required to get some meaningful amount of
porting done. Future PRs should be simpler.
<b>Summary of changes:</b><details>
- Remove old deps:
- boringssl (replaced with mbedtls, lighter, easier to build)
- gflags (replaced with absl::flags)
- Chromium build tools
- New deps to replace parts of Chromium base:
- abseil-cpp
- glog
- nlohmann::json (for tests only)
- Submodules, updates, and CMake build rules for third-party
libraries:
- curl
- gmock/gtest
- Ported internal libraries and their tests by removing Chromium deps
and adding CMake build rules:
- file (now using C++17 filesystem APIs)
- license_notice
- status
- version
- Test improvements
- Removed file tests that can never be re-enabled
- Re-enabled all other disabled file tests
- Debug JSON values when HTTP tests fail
- Fixed chunked-encoding issues in HTTP tests
- Updated and refactored Dockerfiles testing
- All docker files working, with OS versions updated to meet the
new tool requirements
- Local docker builds no longer write files to your working
directory as root
- Local docker builds can now be run in parallel without clobbering
each others' build outputs
- DEBUG=1 can drop you into an interactive shell when a docker
build fails
- Updated and heavily refactored workflows and Dockerfiles
- All docker files now tested in parallel on GitHub, speeding up CI
- All common workflow components broken out and using workflow_call
instead of custom actions
- Self-hosted runners now optional, to make testing easier on forks
- CMake porting works-in-process can now be fully tested on GitHub
- Building ported libraries and passing ported tests on all three
platforms!
- CI hacks for macOS removed, now testing on macos-latest!
- Python2 no longer required! (Only Python3)
- Using strict build flags, treating all warnings as errors.

Issue #346 (Switch to abseil)
Issue #1047 (New build system)
Previously it is possible that the same file path is generated when
the function is called consecutively in the same thread.
The problem can be re-produced in Windows. Does not seem to be
re-producible in Linux and Mac.
Fixes#448, #449.

ImportantFileWriter::WriteFileAtomically uses mkstemp internally,
which set file permission to 0600, which is not what we want.
Update the code to not use mkstemp instead.
Also updated temporary file name logic to include process id in
the name so it can be unique across processes.
Fixes#259
