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.

Issue #346 (Switch to abseil)
Issue #1047 (New build system)
To make shared_library builds work on Windows with MSVS 2019, this
commit:
- Silences a useless warning about a private member in dll-exported
Status class.
- Exports the File class used by packager.exe
- Removes the explicit File dependency in packager.exe in favor of
libpackager, now that File is exported
- Add missing defines in packager.exe and packager_test.exe that
instruct the linker to import Status and File from the library
Closes#318 (shared_library builds on Windows)
Issue #336 (progress toward GitHub Actions workflow to replace Travis
and Appveyor, where we need to build and test shared_library on all
platforms)
b/190743862 (internal; tracking replacement of Travis)

For MP4 files, mp4 parser tries to open and read the same file again
to handle trailing MOOV box.
Open FIFO again may result in packager hang.
Update the code to only attempt to load MOOV for local regular files,
as FIFO and remote files are unseekable anyway.
Fixes#664.

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
