initial build of GVFS provider for Linux

We add the core GVFS.Platform.Linux classes, derived from their GVFS.Platform.Mac equivalents but with appropriate changes for syscall argument signatures and flag values, type definitions, and structure fields (e.g., mode_t is a uint, and the layout of struct stat is quite different). In order to avoid conflicting with the GNOME Virtual FileSystem, we use .vfsforgit as the name of our per-repository private directories, instead of .gvfs, which is used on Windows and Mac. The build tooling is largely a duplicate of the corresponding Mac configuration, with some changes to ensure we build successfully on Linux (e.g., testing for "!= Windows" is no longer sufficient to determine that the platform is OS X, so we add distinct IsLinux and IsOSX build conditions to the .csproj file for GVFS.Upgrader, among other subprojects). The GVFS.sln configuration changes should ensure that the ProjFS.Linux.Managed and GVFS.Platform.Linux subprojects are built on all platforms (and their Mac and Windows equivalents are built on Linux), and that the GVFS.Service.Mac classes are built on Linux, so as to allow the GVFS.UnitTests subproject to build and run successfully on all three platforms. We also build the GVFS.Hooks.Linux and GVFS.Mount.Linux subprojects on both Linux and Windows, just as their Mac counterparts are built on both Mac and Windows. The GVFS.Service binary is, for the time being, only a stub on Linux, as we have yet to determine how (or if) we should handle auto-mounting repositories, and the GVFS.Upgrader binary is also non-functional on Linux at present. Note that for now the BuildGVFSForLinux.sh script does not perform any installation or packaging. Co-authored-by: Ashe Connor <ashe@kivikakk.ee>
