9bdb5e0a92 kernel safemode: Add functions to get options early
Add get_safemode_option_early() and get_safemode_boolean_early() to get
safemode options before the kernel heap has been initialized. They use a
simplified parser.

7b83ce1142 Add KDL command "mapping"
* VMTranslationMap:
  - Add DebugPrintMappingInfo(): Given a virtual address it is supposed
    to print the paging structure information for that address. To be
    implemented by derived classes.
  - Add DebugGetReverseMappingInfo(): Given a physical addresss it is
    supposed to find all virtual addresses mapped to it. To be
    implemented by derived classes.
* X86VMTranslationMapPAE: Implement the new methods
  DebugPrintMappingInfo() and DebugGetReverseMappingInfo().
* Add KDL command "mapping". It supports both virtual address lookups
  and reverse lookups.

7bf85edf58 Allow disabling ASLR via DISABLE_ASLR environment variable
* VMAddressSpace: Add randomizingEnabled property.
* VMUserAddressSpace: Randomize addresses only when randomizingEnabled
  property is set.
* create_team_arg(): Check, if the team's environment contains
  "DISABLE_ASLR=1". Set the team's address space property
  randomizingEnabled accordingly in load_image_internal() and
  exec_team().

c04f3a625a boot loader: Add safe mode blacklist submenu
It's a browser for the system package content, where entries can be
selected to blacklist them. The selected entries are removed from the
packagefs instance in the boot loader, so that e.g. selected drivers
won't be picked up. The paths are also added to the safe mode driver
settings and will be interpreted when the system packagefs instance is
mounted by the kernel.

6c7abe9829 boot loader: Menu[Item] API improvements
* Make Menu and MenuItem polymorphic.
* MenuItem:
  - Make SetMarked() virtual, so it can be overridden.
  - Add SetSubmenu() and Supermenu().
  - Delete the submenu in the destructor.
* Menu:
  - Add Entered()/Exited() hooks. They frame the time the user navigates
    the menu or any of its submenus. The hooks allow for subclasses
    populating their item list dynamically.
  - Add SortItems().
* Update boot loader menu copyright text to include 2013, now that it is
  over soon. :-)

03fb2d8868 kernel: Remove gSchedulerLock
* Thread::scheduler_lock protects thread state, priority, etc.
 * sThreadCreationLock protects thread creation and removal and list of
   threads in team.
 * Team::signal_lock and Team::time_lock protect list of threads in team
   as well.
 * Scheduler uses its own internal locking.

547cd462f8 trim: Added is_called_via_syscall() function.
* And use it in get_trim_data_from_user(), formerly known as copy_*().
* This fixes differentiating between user and kernel buffers.

99086aa323 trim: Target SCSI UNMAP command instead of WRITE SAME.
* The UNMAP command is theoretically much faster, as it can get many block
  ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
  to trim.
* Updated BFS code to collect array ranges to fully support the new
  fs_trim_data possibilities.

077c84eb27 kernel: atomic_*() functions rework
* No need for the atomically changed variables to be declared as
   volatile.
 * Drop support for atomically getting and setting unaligned data.
 * Introduce atomic_get_and_set[64]() which works the same as
   atomic_set[64]() used to. atomic_set[64]() does not return the
   previous value anymore.
