  port::cacheline_aligned_alloc() has arguments swapped which prevents every single test from running.

Summary:
Rework test running script.
  New options SuiteRun - runs specified executables as google suite
  test cases in parallel.
  Run - this option now runs executables in parallel the same as 'tests'
  RunAll - scans for test executables and attempts to run them all
  as suites except those mentiones in RunOnly (hardcoded in the script)
  or specified either in $ExcludeTestCases $ExcludeTestExe

Summary:
Separate a smal subset of tests in DBTest to DBBasicTest. Tests in DBTest don't have to run in CI tests on platforms like OSX, as long as they are covered by Linux.

Add db_test2

Conditionally retrofit thread_posix for use with std::thread
  and reuse the same logic. Posix users continue using Posix interfaces.
  Enable XPRESS compression in test runs.
  Fix master introduced signed/unsigned mismatch.

  Increase concurrency to 18
  Fix exclusion but in the ps script

  Add sequential rerun for any failed tests. Add env_test case.
  Limit concurrency
  Allow to specify individual tests
  Take $Limit into account when displaying number of tests

  Test code errors are currently blocking Windows Release builew
  We do not want spend time building in Release what we can not run
  We want to eliminate a source of most frequent errors when people
  check-in test only code which can not be built in Release.
  This feature will work only if you invoke msbuild against rocksdb.sln
  Invoking it against ALL_BUILD target will attempt to build everything.

  Add an optimized build config switch for faster test runs
  Change compiler options to introduce more opitmizations and be more inline with MS internal switches.
  Make appveyor build to utilize all the avaiable cores on the VM (parallel)
  Introduce new appveyor configuration for daily test runs as it would take too long
  to run db_test after each checkin even in paralell.
  With some exclusions we make it in 38 minutes. We currently fail to install ramdisk during the build.
  Add a powershell script to faicilitate paralell run for db_test cases.

Summary: Check in a simple auto-build manfiest so that developers can issue ad-hoc build for Windows in Appveyor.

Test Plan: Run it in test branch test_appveyor and it works well.
