2019-11-25	Minor VFS2 interface changes.	Jamie Liu
	- Remove the Filesystem argument from DentryImpl.Ref(); in general DentryImpls that need the Filesystem for reference counting will probably also need it for other interface methods that don't plumb Filesystem, so it's easier to just store a pointer to the filesystem in the DentryImpl. - Add a pointer to the VirtualFilesystem to Filesystem, which is needed by the gofer client to disown dentries for cache eviction triggered by dentry reference count changes. - Rename FilesystemType.NewFilesystem to GetFilesystem; in some cases (e.g. sysfs, cgroupfs) it's much cleaner for there to be only one Filesystem that is used by all mounts, and in at least one case (devtmpfs) it's visibly incorrect not to do so, so NewFilesystem doesn't always actually create and return a new* Filesystem. - Require callers of FileDescription.Init() to increment Mount/Dentry references. This is because the gofer client may, in the OpenAt() path, take a reference on a dentry with 0 references, which is safe due to synchronization that is outside the scope of this CL, and it would be safer to still have its implementation of DentryImpl.IncRef() check for an increment for 0 references in other cases. - Add FileDescription.TryIncRef. This is used by the gofer client to take references on "special file descriptions" (FDs for files such as pipes, sockets, and devices), which use per-FD handles (fids) instead of dentry-shared handles, for sync() and syncfs().

2019-09-03	Impose order on test scripts.	Adin Scannell
	The simple test script has gotten out of control. Shard this script into different pieces and attempt to impose order on overall test structure. This change helps lay some of the foundations for future improvements. * The runsc/test directories are moved into just test/. * The runsc/test/testutil package is split into logical pieces. * The scripts/ directory contains new top-level targets. * Each test is now responsible for building targets it requires. * The install functionality is moved into `runsc` itself for simplicity. * The existing kokoro run_tests.sh file now just calls all (can be split). After this change is merged, I will create multiple distinct workflows for Kokoro, one for each of the scripts currently targeted by `run_tests.sh` today, which should dramatically reduce the time-to-run for the Kokoro tests, and provides a better foundation for further improvements to the infrastructure.
