Release 1.29.0.0

[jessk-msft]

Version [1.29.0.0]

• Fixing virtual file hydration to be excluded from system directory notifications.
  This avoids unecessary FILE_NOTIFY_INFORMATION or DirectoryWatcher events indicating
  a virtual file has been modified, when it's only been hydrated as-expected on read.
  This technique is common across filter drivers. This is only supported for STREAM
  populate method (default). New unit test TestReadDirectoryChanges for verification.
• Additional unit test varible P4VFS_TEST_SERVER_ROOT for overriding the root directory
  for the test servers. This better facilitates running all tests remotely on a local
  virtual machine with including kernel mode debugging. Includes support for
  RestartPerforceServer script to quick spin-up of existing server on override drive
• Reconfiguring our 32 bit driver allocation pool tags to 4-byte string "Pvs*"
• Fixing bug recieving large messages to/from the P4VFS.Service. This was typically
  encountered when using global "-x " with a file containing many arguments.
  There's a new ReflectPackage message which is now used by SocketModelCommunicationTest
  to stress test a wide range of message sizes
• Fixing unit tests deterministic random byte generation to more randomly include
  zero as randomly as possible
• Support for additional registry keys to set defined in the setup application configuration
  file (typically named P4VFS.Setup.xml residing in the same folder as the installer).
  This is helpfull for setting possibly setting a version key to indicate what settings
  template was also installed.
