Generate additional .vcproj files in miscellaneous top-level components.

This also updates the .vcproj files themselves to fix minor stylistic
incompatibilities with the rest.  Affected .vcproj files:
* No change (byte-for-byte identical):
    media\build\media.vcproj
    media\build\media_player.vcproj
    media\build\media_unittests.vcproj
    google_update\ondemand_updates.vcproj
* Remove .\ prefix where inconsistent with the rest of a filelist:
    rlz\rlz.vcproj
    breakpad\breakpad_handler.vcproj
* Add empty <ToolFiles>, <References> and <Globals> sections:
    breakpad\breakpad_sender.vcproj
* Add explicit RootNamespace attribute:
    sdch\sdch.vcproj
* Use Windows-canonical \ separators:
    sdch\sdch.vcproj
* Remove unnecessary Filter and UniqueIdentifier attributes from
  <Filter> declarations:
    sdch\sdch.vcproj

Additional cleanups along for the ride:
* Split breakpad\SConscript logic into separate
  breakpad_{handler,sender}.scons files.
* Add a media\media_player.scons configuration.

Re: the changes to sdch.vcproj, I don't believe we need the Filter and
UniqueIdentifier attributes, but let me know if you see a reason to keep them.

LGTM
(parts of the scons files are rubber stamped)

I don't understand why you keep that part.
