This feeds into efforts to create a working install target.
The order of headers is still funky, and was "fixed" by clang-format,
but in a way that doesn't exactly align with the style guide. Further
cleanup of header order is coming in a follow-up PR.
All HTTP-based tests now use an embedded test server instead of
httpbin.org, which makes them much faster and more reliable.
These more reliable tests also exposed some issues that began recently
with PR #1201. HttpFile's Flush() semantics were different than those
documented for files in general. Flush() used to close the file for
uploading, so that no further writes were allowed, but the documentation
stated that it would only flush data to its destination. PR #1201
brought HttpFile's Flush() in line with the docs, but gave us no way to
terminate a chunked upload.
This adds a new method to File called CloseForWriting(), which
terminates a chunked upload for HttpFile. The only other implementation
that does anything is UdpFile, which uses the socket library function
shutdown() to terminate writes while allowing reads.
This also tweaks HttpFile::CloseWithStatus() so that it will not
generate an error if the file is closed before the HTTP response is
written to the download cache.
This modifies the test HttpFileTest.MultipleWrites so that the file is
Flushed after each chunk. This adds test coverage for the changes
introduced in PR #1201.
Fixes#1224 (missing test coverage for HttpFile::Flush)
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>

Issue #346 (Switch to abseil)
Issue #1047 (New build system)
Previously packaging completes successfully without any error
or warning.
With the fix, an error will be reported if write fails. It may
appear as "Cannot close file error" as we use threaded IO, which
could delay the error reporting until Close() call, so the user
of the File API needs to make sure Close() returns successfully.
Also fixed a deadlock in threaded_io_file if internal_file->Write
fails.
Fixes#160
