U-DESKTOP-SPFP6AQ\twistedtechre 96ec45a82f samples/tasks: repair database demo, add decompress test 
Two related changes under samples/tasks/.

samples/tasks/database: restore a buildable state

  The database demo had bit-rotted to the point where neither the
  C source nor the Makefile matched the current tree:

    * main_msg_queue_push: retro_task_queue_msg_t gained a
      retro_task_t* first parameter
    * main_db_cb: retro_task_callback_t gained the same
    * core_info_init_list: added a sixth bool *cache_supported
      parameter
    * Makefile: hash/rhash.c was renamed to hash/lrc_hash.c
    * Makefile: 7zip source list was stale -- 7zIn.c was renamed to
      7zArcIn.c, and BraIA64.c / CpuArch.c / Delta.c were added
    * Makefile: missing sources for trans_stream*, rzip_stream,
      features_cpu, rtime, rxml, m3u_file, logiqx_dat,
      manual_content_scan, yxml
    * link: missing -lm for roundf

  Several symbols reached via task_push_dbscan are defined only
  when RARCH_INTERNAL is set, which would transitively require
  linking most of retroarch.c, frontend_driver.c, runloop.c,
  configuration.c and the UI/video subsystems.  Since this sample
  exercises only the task queue, it provides lightweight stubs for:

    * msg_hash_get_help_us_enum  (real def in intl/msg_hash_us.c)
    * msg_hash_to_str_us         (real def in intl/msg_hash_us.c)
    * config_get_ptr             (real def in configuration.c)
    * runloop_msg_queue_push     (real def in runloop.c)
    * retroarch_override_setting_is_set
    * ui_companion_driver_notify_refresh
    * video_display_server_set_window_progress
    * frontend_driver_get_free_memory
    * dir_list_new_special       (real def in retroarch.c)

  All stubs are either no-ops or return a conservative value that
  lets the surrounding code bail gracefully; none of them are
  exercised on the happy dbscan path.

  After these changes the demo builds cleanly on a stock Ubuntu
  host (build-essential, zlib1g-dev, libpthread), and both
  `database_task` with no args and `database_task <5 dirs>` exit
  with the expected status.

samples/tasks/decompress: new standalone regression test

  Adds archive_name_safety_test, a 23-case predicate unit test for
  the archive_name_is_safe() function in tasks/task_decompress.c.

  This test was originally developed alongside the Zip Slip patch
  in the first security round and held out of
  libretro-common/samples/ because it exercises code in tasks/
  rather than libretro-common/.  samples/tasks/ is its natural
  home.

  The test keeps a verbatim copy of the predicate and validates it
  against a table of safe / unsafe paths:

    * safe:   file.txt, dir/file.txt, a.b/c, ..foo, foo..
    * unsafe: .., ../etc/passwd, foo/..//bar, /etc/passwd,
              \windows\system32, C:\evil, c:/evil, ..\..\windows,
              foo\..\bar, empty string, NULL

  If the predicate in task_decompress.c is ever edited, the copy
  here must be updated to match -- this is noted in the test file's
  header.
