app_server pointer/ownership cleanup: trivial changes

Split apart the work done in https://review.haiku-os.org/c/haiku/+/2695
in smaller, easier to review parts.

This commit contains self-contained/local changes that are unlikely to
cause problems.

Cleanup, no functional change intended. Style, line length, early returns,
variable names, added TODO, variable declaration on first use, simplify some
code, add missing sanity checks...

* Use std::nothrow and check the bitmap/cursor allocations.
* CID 2500 and 2501: Check the BMessage::FindData() returns.
* Defensive programming: Take the bitmap/cursor BitsLength() into account when
copying the data back.
* Some style cleanup, automatic whitespace cleanup.

Applied (part of) a patch by Kaliber, attached to ticket #5875. Thanks!
Will commit the rest later.

* Added BCursorID enumeration in App Kit's Cursor.h and new constructor which
takes such an id.
* Reused the existing mechanism to to have hardcoded tokens for the system
cursors, i.e. removed cursor_which enumeration from ServerProtocol.h and
used BCursorID where cursor_which was previously used.
* Reworked CursorManager.h and CursorSet.h accordingly and removed some methods
that where intended to replace system cursors with client cursors, since
those would break the reference counting and forget to maintain the cursor
list.
* Replaced the cursors in CursorData.h/cpp with the new ones I just designed.
* Removed HaikuSystemCursor.h and HaikuLogo.h from the source, as those are/were
no longer used.

I hope I will not get too much beating for this one... :-) I know the new
default cursor is slightly larger, but I believe the old one was just too small.
Also I noticed that the cursor may be slightly too dark, at least the old one
seems noticeably brighter when compared side by side (the new one has a slight
gradient). That is something I may correct at least. Otherwise I hope nothing
is broken, I've tested in QEMU and so far everything works as intended.

* Removed headers/private/servers/app - everything is in src/servers/app now.
* Removed DisplaySupport.h, wasn't needed anymore.
* Removed private color set functions from InterfaceDefs.cpp - we might want
something similar, but definitely not like that.
* Minor cleanup, added some missing licenses.

various changes to handling custom cursors:
* all cursors owned by a team are visually different,
or (iaw) an already existing cursor is reused when
it is set by the client again
* changed various occurances of cursor data from "int8*"
to "uint8*"
* ServerCursors also remember the R5 data from which
they were created
* the reference counting and destruction of
ServerCursors changed: The cursor knows it is attached
to a CursorManager and one can simply use
ServerCursor::Acquire() and Release() and the reference
counting and everything is being taken care of
* destroying a ViewLayer will now correctly release a set
ServerCursor
* fixed a race condition when setting a cursor through
BView::SetViewCursor(): If the client code looks like this:

BCursor cursor(cursorData);
someView->SetViewCursor(&cursor, false);

there is a relatively high chance the BCursor destructor
told the ServerApp thread to destroy the cursor before
the ServerWindow thread got to "acquire" the cursor for
use by the view layer. The very same problem is likely the
reason that SetViewCursor works to unreliably on R5, even
when the "sync" flag is set to "true" (although it should
theoretically work in that case).

all these fixes make WonderBrush work fine again with the
new support of custom cursors.... coded by axeld and myself
(the joys of pair programming :-)

Some work on cursors:
* Fixed a myriad of bugs all over the place, ranging from locking errors to
deleting objects that don't belong to the one deleting them (hello HWInterface!)
* Almost all ServerWindow cursor stuff was broken; I've replaced all commands
to set a cursor with a single one AS_SET_CURSOR.
* Renamed some cursor commands.
* Changed the (broken) way ServerApp::fAppCursor was maintained - the application
cursor is now NULL as long as possible.
* Removed superfluous ServerCursor app signature stuff.
* The BApplication will no longer duplicate the default/I-beam cursors, it will
just reuse the default ones which now have fixed tokens.
* As a result, changing the cursor is now working as expected, closing bug #102.
* Rewrote Cursor.h, renamed private members to match our style guide.
* Minor cleanup.

What's still left to be done is reference counting the cursor objects to make them
work right and reliable.

Removed {set|get}_syscursor according to DW. Scratch that last sentence in the last commit, with this Appearance builds again.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13727 a95241bf-73f2-0310-859d-f6bbb57e9c96

All cursor related changes:

* Moved setting the default cursor from ServerScreen to Desktop
* Getting the default cursor is now done using the CursorManager
* Removed outdated setcursor from SysCursor.cpp (we have a new implementation by now)
* Renamed SysCursor.cpp to CursorSet.cpp as that's what it is
* Moved headers/private/app/SysCursor.h to headers/private/servers/app/CursorSet.h
* Removed some unneeded header includes along the way

There remains {set|get}_syscursor now in CursorSet.cpp. Serverside for these are not implemented
and they are obvious hacks. Do we need to keep them?
Also this commit _would_ break Appearance, but 1) all the related code is currently commented out
with the comment "cursor set management belongs in another app" and 2) it is already broken
because of ColorSet.
