[telemetry] Support absolute paths by changing file:/// to file://. More robust file path handling.

file:///a/b/c.html == absolute path. This follows RFC-1738 (empty hostname refers to localhost).
file://a/b/c.html == relative path. In the RFC, "a" is technically the hostname, but we're just gonna use it as part of the path.

http_server:
- Support relative paths at the command-line for memory_cache_http_server.
- Removal of duplicate paths.
- Correct path prefix calculation. (commonprefix is a string prefix, not a path prefix.)
- Correct UrlOf so it works based on path, not on an assumption that serving_dirs_and_file returns a specific value.

page:
- Remove _UrlPathJoin. Its behavior is awkward for absolute paths. Its backslash to slash conversion should be unnecessary if we always use proper OS paths (except in UrlOf).
- Split serving_dirs_and_file into page.file_path, page.serving_dir, and page_set.serving_dirs.


BUG=None.
