Refactoring Bisect method in bisect-builds.py

This CL simplified the prefetch handling and conditions like

```
    if ((answer == 'g' and good_rev < bad_rev)
        or (answer == 'b' and bad_rev < good_rev)):
```

The new implementation reversed the rev_list to ensure rev_list[0] is
good and rev_list[-1] is bad and simply re-orders the return value. This
also fixed the issue that unknown was not working properly. Tests were
added to cover more cases.

This CL also improved the error report during run_revision. When an
error happens during run_revision, the zip_file and the tempdir will
remain on the disk while evaluating (normally AskIsGoodBuild), so that
users can debug the failure with the downloaded and unzipped archive.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
