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. :-)

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.

7f64b301b1 Reduce lock contention in kernel port subsystem.
* Replace ports list mutex with R/W-lock.

* Move team port list protection to separate array of mutexes.
  Relieve contention on sPortsLock by removing Team::port_list from its
  protected items. With this, set_port_owner() only needs to acquire the
  sPortsLock for reading.

* Add another hash table holding the ports by name. Used by find_port()
  so it doesn't have to iterate over the list anymore.

* Use slab-based memory allocator for port messages. sPortQuotaLock was
  acquired on every message send or receive and was thus another point
  of contention. The lock is not necessary anymore.

* Lock for port hashes and Port::lock are no longer locked in a nested
  fashion to reduce chances of blocking other threads.

* Make operations concurrency-safe by adding an atomically accessed
  Port::state which provides linearization points to port creation and
  deletion. Both operations are now divided into logical and physical
  parts, the logical part just updating the state and the physical part
  adding/remove it to/from the port hash and team port list.

* set_port_owner() is the only remaining function which still locks
  Port::lock and one or two of sTeamListLock[] in a nested fashion.
  Since it needs to move the port from one team list to another and
  change Port::owner, there's no way around.

* Ports are now reference counted to make accesses to already-deleted
  ports safe.

* Should fix #8007.

cc65466f0d ARM: kernel: Make KDL more useful on ARM
This adds the -mapcs-frame compiler flag for ARM to have "stable"
stack frames, adds support to the kernel for dumping stack crawls,
and initial support for iframes. There' much more functionality
to unlock in KDL, but this makes debugging already a lot more
comfortable.....

Additional changes:
* Add src/system/kernel/lib/zlib, which builds a kernel version of zlib,
  needed by packagefs.
* BuildFeatures: Add a build feature "gcc2" to allow for easier checks.
* Referenceable.cpp: Include <OS.h> instead of <debugger.h>. The latter
  is not needed and prevents building for the build platform.
* zlib/zutil.h: Fix gcc 2 build. We really should use the external
  package instead.

c24adb2950 Rework DefaultNotificationService registration.
- Instead of implicitly registering and unregistering a service
  instance on construction/destruction, DefaultNotificationService
  now exports explicit Register()/Unregister() calls, which subclasses
  are expected to call when they're ready.

- Adjust all implementing subclasses. Resolves an issue with deadlocks

* Add "bool kernel" parameter to vfs_entry_ref_to_path(), so it can be

* _user_entry_ref_to_path(): Use the calling team's I/O context instead
  of the kernel's. Fixes the bug that in a chroot the syscall would
  return a path for outside the chroot.

e85e399fd7 commpage: randomize position of commpage
This patch introduces randomization of commpage position. From now on commpage
table contains offsets from begining to of the commpage to the particular
commpage entry. Similary addresses of symbols in ELF memory image "commpage"
are just offsets from the begining of the commpage.

This patch also updates KDL so that commpage entries are recognized and shown
correctly in stack trace. An update of Debugger is yet to be done.

5e0c3db286 Account for the physical map area in the kernel VM space. Fixes #9547.
The physical memory map area was not included in the kernel virtual
address space range (it was below KERNEL_BASE). This caused problems
if an I/O operation took place on physical memory mapped there (the
bad address error seen in #9547 was occurring in lock_memory_etc()).
Changed KERNEL_BASE and KERNEL_SIZE to cover the area and add a null
area that covers all of it. Also changed X86VMTranslationMap64Bit to
handle large pages in Query(), as the physical map area uses large
pages.
