I'm not sure how we'll coalesce around a consensus, but I figure we should
lay out the options in one place. Even if this doesn't make it into the
beta, we should be clear on this going forward.

Option 1 - 14.10 Use microsoft toolset version based on cl.exe version -5.
This is the official version of the c++ toolset that microsoft has been
pushing (somewhere). The new $(VCToolsVersion) macro is "14.10.25017", this
macro is not available in previous versions of visual studio.

build bootstrap would use bootstrap.bat vc1410
build of source would use b2 toolset=msvc-14.10
build would generat libraries of the format
libboost_NAME_vc1410-OPTIONS-1_64.lib
config would auto-link libraries of the same format

Option 2 - 14.1 Use the abbreviated toolset version that microsoft uses for
their toolset version. The $(PlatformToolsetVersion) macro is "141". In
VS2015 this was "140".

build bootstrap would use bootstrap.bat vc141
build of source would use b2 toolset=msvc-14.1
build would generat libraries of the format
libboost_NAME_vc141-OPTIONS-1_64.lib
config would auto-link libraries of the same format

Option 3 - 15.0 Use the visual studio version. The $(VisualStudioVersion)
macro is "15.0". In VS2015 this was "14.0".

build bootstrap would use bootstrap.bat vc15
build of source would use b2 toolset=msvc-15.0
build would generat libraries of the format
libboost_NAME_vc150-OPTIONS-1_64.lib
config would auto-link libraries of the same format

A alternative that could be made to any of the options 1-3 option would be
to bring the b2 toolset in line with whatever we chose for the name,
replacing the "msvc-" with "vc". For example option 1-a would be:

build bootstrap would use bootstrap.bat vc1410
build of source would use b2 toolset=vc1410
build would generat libraries of the format
libboost_NAME_vc1410-OPTIONS-1_64.lib
config would auto-link libraries of the same format

I *think* that is all the reasonable options. Let the consensus form!
