Bug 1186060 - Build with Visual Studio 2015 Update 1; r=ted, ehsan This commit switches Windows builds from Visual Studio 2013 to Visual Studio 2015 Update 1. Previously, Visual Studio was installed on the builders as part of the base system image. Starting with this commit, we obtain Visual Studio from a pre-generated, self-contained archive containing the executables, Windows SDK, and other support files. This means that new Windows toolchains can be installed without having to modify configuration of machines in automation! The mozconfigs for Visual Studio 2015 are a bit different from existing mozconfigs. Because it appears to be completely redundant and not necessary, the LIBPATH variable has been dropped. The order of paths in PATH, LIB, and INCLUDE has changed. The new order more accurately reflects what would be defined by vcvarsall.bat. As part of switching to Visual Studio 2015, the Universal CRT is now required. So, the 2015 mozconfigs export WIN_UCRT_REDIST_DIR to define the location to those files. The switch to Visual Studio 2015 also involves the switch from the Windows 8.1 SDK to the Windows 10 SDK. However, we still target an old version of Windows, so this hopefully shouldn't have any significant fallout. It's worth noting that switching to Visual Studio 2015 makes builds - especially PGO builds - significantly faster. Our PGO build times in automation are ~1 hour faster. Our regular builds appear to be a few minutes faster. MozReview-Commit-ID: Pa5GW8V87Q

Please be apprised of the following Legal Notices:

A) The U.S. District Court for the Eastern District of Virginia has
ruled that the Netscape Navigator code does not infringe Wang's U.S.
Patent No. 4,751,669 ("the '669 Patent") because: 1) HTML is not
Videotex as defined by the '669 patent; 2) web servers are not central
suppliers; and 3) Navigator does not "connect," as defined by the '669
Patent, to web servers on the Internet. Wang may appeal this decision to
the Federal Circuit. Wang contended that its Patent disclosing a
"Videotex" system, is infringed by the following functionality in the
Netscape Navigator code: 1) the animated logo and status line indicators
--See Claims 1,8 and 9; 2) the "File Save As" function --See Claims
23-27; 3) Bookmarks and Rename Bookmarks in the Properties window --See
Claims 20-22; 4) storing HTML, GIF, and JPEG files and adding filename
extensions --See Claim 38

B) Intermind owns pending U.S. patent applications on communications
systems which employ metadata ("channel objects") to define a control
structure for information transfer. The Netscape code does not infringe
as released; however, modifications which utilize channel objects as
described by Intermind should be considered carefully. The following is
a statement from Intermind: "Intermind's claims fundamentally involve
the use of a control structure to automate communications. ...The
essence of Intermind's top claim is that two devices sender and receiver
have persistent storage, communicate over a network, and exchange a
control structure including metadata which describes: 1) what
information is to be updated, 2) when to update this information, and 3)
how to transfer the updated information. In addition, at least the
receiving device must be able to process the metadata in order to
perform the update determination and transfer. Any digital
communications system which incorporates all of these elements will be
covered by Intermind's patents." See

C) Stac, Inc., and its licensing agent Hi/fn, own several patents which
disclose data compression methods implementing an LZS compression
algorithm, including U.S. Patent Nos. 4,701,745 and 5,016, 009 ("the
Stac Patents"). The Netscape Communicator code does not perform
compression. If you modify the Netscape source code to perform
compression, please take notice of the Stac Patents.

D) Netscape Communications Corporation ("Netscape") does not guarantee
that any source code or executable code available from the
domain is Year 2000 compliant.
