findutils: use the HaikuPorts package.

* removed in-tree version.
* added as bootstrap package.
* note: HaikuPorts package has no rdef for binaries.
ScreenSaverSettings: Silly indentiation fix
ScreenSaver: check function return values for success
ScreenSaverSettings: check find_directory return value
ScreenSaverRunner: clarify some comments
ScreenSaverRunner: check return value of methods
ScreenSaverRunner: treat load_add_on return value like an image_id

... rather than a status_t, because that's what it is.
ScreenSaverRunner: print errors to stderr instead of stdout.

Also print on a couple of new error cases:
* print and error if fSaver is NULL,
* print and error if unload_add_on failed.
ScreenSaverSettings: Check that name is valid

... before trying to use it in GetModuleState() and SetModuleState()

also, rename the stateMsg variable to stateMessage (already correct in header)
ScreenSaverRunner: Fix segmentation fault loading bad screen saver.

When Settings.ModuleName() returned NULL here we got a segmentation fault
trying to access the pointer.

I ran into this trying to load up a non-screensaver executable in ScreenSaver,
it crashed instead of doing the right thing and refusing to load.

Also, since we go to the trouble of saving this to a variable, we should actually use it.
Add gawk package for x86, x86_64 and x86_gcc2.
ScreenSaver: pass in true to get a preview

Fixes #10602

This was a simple mistake on my part, unfortunately this means that
a bunch of screen savers that showed preview fine before no longer do.
gawk: use the HaikuPorts package.

* left the in-tree version as its libintl is used by gdb.
* added as bootstrap package.
PackageInstaller: Unbreak selecting custom install folders.

BFilePanel always sends B_CANCEL when it hides (as documented in the BeBook),
not just when the user cancels the file panel. Track what message we expect
and only react to B_CANCEL when it means the user really canceled selecting
the target folder.
Gravity: Add break fixing white option
Fix missing break statement (CID #1108253)
Use delete[] on array (CID #701816)
ARM: Simplify board specification

* Don't assume verdex as it isn't clear this was
  occurring.
* Make an educated guess on HAIKU_BOOT_PLATFORM
  based on provided board (but still allow it to
  be overridden)
* Error out if user doesn't populate
  HAIKU_BOOT_PLATFORM or enters an unknown board
  name.
* You need to add "-sHAIKU_BOOT_BOARD=xxx" to
  your jam to build for the proper ARM device.
* Rename beagle to beagleboneblk as per the
  documentation.
Font.cpp: Style cleanup

 * Unify asterisk style
 * switch indentation style of FontList declaration
 * Order FontList methods according to declaration
 * Use named constants in default BFont constructor for spacing and encoding.
Font: Work on support for spacing modes.

 * Change default spacing to B_BITMAP_SPACING. The BeBook does not document
   what the default spacing is, and I have no BeOS install handy to check.
   However, I believe that B_BITMAP_SPACING is what should be the default,
   since it gives the best visible result for the common use-case.
   In terms of implementation, there is no change, since spacing was ignored
   until now and the behavior was that of B_BITMAP_SPACING. This change could
   however break BeOS apps which assume B_CHAR_SPACING is the default and don't
   set it on new when they need it. Sample code in the BeBook however shows
   setting B_CHAR_SPACING on a newly created BFont.
 * Implement B_STRING_SPACING to do something sensible. The BeBook documentation
   is completely vague in what it is actually supposed to do. Given the
   possibilities of FreeType, I am implementing it to enable the use of
   kerning. Kerning optimizes the spacing between two glyphs, for example, it
   would decrease the spacing between "T" and "e" in the string "Test" for
   our default font. Untested.
