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.

e551626f40 Implement support for a SYS:ENV attribute on executable
__flatten_process_args() does now have the executable path as an
additional (optional) parameter. If specified, the function will read
the file's SYS:ENV attribute (if set) and use its value to modified the
environment it is preparing for the new process. Currently supported
attribute values are strings consisting of "<var>=<value>" substrings
separated by "\0" (backslash zero), with '\' being used as an escape
character. The environment will be altered to contain the specified
"<var>=<value>" elements, replacing a preexisting <var> element (if
any).

A possible use case would be setting a SYS:ENV attribute with value
"DISABLE_ASLR=1" on an executable that needs ASLR disabled.

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().

fb52b1f8b4 VFS FIFO: Enlarge FIFO buffer sizes
* Increase FIFO buffer capacity from 32 to 64 KiB and the FIFO atomic
  write size ({BUF_SIZE}) from 512 bytes to 4 KiB (both like Linux).
* Fix *pathconf(..., _PC_PIPE_BUF). It was returning 4 KiB although the
  implemented atomic write size was 512 bytes only. Now both *pathconf()
  and the FIFO implementation refer to the same constant.

ee8e91583e BPackageManager::UserInteractionHandler: Make non-abstract
Most of the hooks don't strictly need a non-empty implementation. The
defaults now simply throw exceptions in those that do. This allows the
class to be instantiated, which is useful when a BPackageManager is only
used for finding packages.

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. :-)

3a7e0b0014 packagefs: Support blacklisting entries in packages
In each installation location, it is now possible to create a settings
file "packages" that allows to blacklist entries contained in packages.
The format is:

Package <package name> {
	EntryBlacklist {
		<entry path>
		...
	}
}
...

<package name> is the base name (no version) of the respective package
(e.g. "haiku"), <entry path> is an installation location relative path
(e.g. "add-ons/Translators/FooTranslator").

Blacklisted entries will be ignored by packagefs, i.e. they won't appear
in the file system. This addresses the issue that it may be necessary to
remove a problematic file (e.g. driver, add-on, or library), which would
otherwise require editing the containing package file.

The settings file is not not "live". Changes take effect only after
reboot (respectively when remounting the concerned packagefs volume).

1c776bfe37 Lock screensaver window directly
By passing the window pointer to ScreenSaverRunner contructor and using that
to lock the window when drawing instead of getting the window from the
Window() method of the view. This is safer.

d34a680c04 Screen Saver: fix race condition
Start the screensaver in the window thread instead of the runner
thread so that there is no lock contention for the window lock in
the runner thread when the saver starts.

The view that gets drawn into is assumed to have been prepared before
being passed to the runner thread, and this assumption has been made
true for the screensaver preview and screen_blanker apps.

Eliminate fHasStarted and the corresponding HasStarted() method in
ScreenSaverRunner as they are no longer needed.

Drawing still happens in the runner thread, and still needs to lock
the window thread potentially causing contention, yet, there
is a timeout here so the contention won't freeze the screensaver window,
only delay drawing the screensaver.

Drawing could be moved to the window thread via message passing to avoid
lock contention with the window but this would defeat a big part of the
purpose of having a separate rendering thread.

This fixes #10125 and #4260

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.

986e4abce4 Add new API find_path[s](), find_path_for_path()
The new functions are meant to replace many uses of find_directory():
* find_paths() is supposed to be used when the directories of a certain
  kind in all installation directories are needed (e.g. font
  directories, add-on directory, etc.). Using this API makes code
  robust wrt addition or removal of installation locations.
* find_path() is supposed to be used when files/directories associated
  with a loaded program, library, or add-on need to be found (e.g. data
  files or global settings).
* find_path_for_path() is similar to find_path(), but it starts from a
  given path instead of an image.

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.

3f40dcb6b4 PackageWriterImpl::_AttributeRemoved(): Update string cache
When removing a string attribute, decrement the referenced string's
usage count in the string cache. This fixes the potentially incorrect
usage counts in update mode. Not a serious problem, but it could lead
to only singly (or no longer) used strings to be written to the string
subsection instead of encoding them inline and thus to slightly greater
file sizes.

bd336e3abc Update semantic shortcuts
Update BKeymap::GetModifiedCharacters() to translate a given character
and set of modifiers filling out a list of all characters that match for another
set of modifiers.

This allows us to, for example, get all characters in the normal map that
have the '+' character in the corresponding shift map.

It is fully generic allowing one to get a list of characters in any map given
a character and modifiers of another map.

Also I converted from using a BList to using a BObjectList.

With this, along with BWindow::HasShortcut(), the semantic shortcuts now
work not only with Command+'=', but any key in the normal map that has
'+' in it's shift map as long as it isn't already taken by another shortcut.

1d04310459 Keymap: Add a method to get modified characters for a key
This method fills out the passed-in BList of modified utf-8 characters for
a given utf-8 character and set of modifiers.

For example if you pass in "=" and B_SHIFT_KEY the list will get filled
out with each character in the shift map that has "=" in the normal map.

Each supported keymap modifier combination is available.

The reason this is useful will soon become apparent.

A BList is used because the character might be mapped multiple times,
for example if you have a Mac keyboard you've got two "=" keys, one in
0x1d and one in 0x6a.

The caller is responsible for creating the BList and destroying it as well as
freeing the resulting character strings.

916be2df3c Consolidate adding add-on directories
This builds off of hrev46243 adding add-on directories all in one place
in AddOnMonitorHandler instead of repeating the code 3 times in
IndexServer, AddOnManager, and MediaAddOnServer.

The safe mode checking in InputServer is now redundant since it all
gets funneled into AddOnMonitorHandler::AddAddOnDirectories()
and the safe mode flags are checked there.

We should probably remove the InputServer::SafeMode() method, but,
I didn't want to break anything that depended on it so I left it.
