b1bc7a1b5d TextEditor: Don't try to load contents of files we didn't even open 
If the CFile::open() call fails, we shouldn't continue with trying to
load the file.

d56786ccd8 TextEditor: Avoid an unnecessary whole-file copy when opening something 
This was left over from before we had the StringView(const ByteBuffer&)
constructor to help us.

5768b384b9 Kernel: Give each TTY 1 KB of input buffer 
This papers over an immediate issue where pseudoterminals would choke
on more than 16 characters of pasted input in the GUI terminal.

Longer-term we should find a more elegant solution than using a static
size CircularQueue for this.

32810a920f Kernel: Implement kill(0, signal)

calling process.

748b38d80f GTextEditor: Fix obvious bug in find() 
We forgot to rewind the search cursor after a partial match, which
would make us fail to find "xxy" in "xxxxy".

1ca6adee90 Terminal: Allow selecting words by double-clicking them 
Bonus feature: also allow selecting the whitespace in-between words by
double-clicking that. :^)

fae379b1f0 TextEditor: Search box should find on return, close itself on escape 
This patch adds basic keyboard access to the search box. We also yield
focus back gracefully to the text document when the search box is no
longer wanted.

Focus should probably move automatically when an ancestor of the
currently focused widget if made invisible..

You can get to it via Edit/Find, or by pressing Ctrl+F.

933a98f8fa Kernel: Make Lock::lock() assert early that we're not in the scheduler 
The scheduler is not allowed to take locks, so if that's happening,
we want to make that clear instead of crashing with the more general
"Interrupts disabled while trying to take Lock" error.

bb74832dd6 TextEditor: Add a search bar that allows you to search for text 
If the text is not found, we show a friendly message box that says we
didn't find the text! :^)

0c72371ad9 GTextEditor: Implement a simple text search API 
- GTextRange find(const StringView& needle, const GTextPosition& start)

This function searches for the needle in the haystack (the full text)
and returns a GTextRange for the closest match after "start".
If the needle is not found, it returns an invalid GTextRange.
If no "start" position is provided, the search begins at the head of
the text document. :^)

d5431a6df8 GTextEditor: Rename is_automatic_indentation_enabled() API 
The previous name was is_automatic_indentation() which sounds weird.

9e5c5627d5 GTextEditor: Give Line objects a back-reference to the GTextEditor 
This will allow us to do more complicated things in Line without having
to pass the editor around all the time.

af840af1ce Documentation: Let's have a coding style document 
This is only meant to be about higher-level coding style, not the small
things like brace placement, indentation, etc. For all of that we just
obey clang-format.

The netcat-lite "nc" utility is where we should put all of the various
"lightweight" TCP/UDP client features.

All block devices should have a block size, after all. This defaults to
PAGE_SIZE if no size is specified.

a division by zero occured while calculating the offset.

f7dce05c82 LibGUI: Remove confusing GModelNotification concept 
This was a bad idea and it didn't stick. Instead we should just use the
simple "on_foo" hook functions like we do for everything else. :^)

4f3234148a Inspector: Show remote object properties in a table view 
This patch expands the object model of this program quite a bit.
We now have a RemoteProcess object that contains a list of remote root
RemoteObject objects.

The RemoteProcess vends a RemoteObjectGraphModel&, and indices in that
model have internal_data() pointing to a corresponding RemoteObject.
RemoteObjects in turn vend a RemoteObjectPropertyModel&, which is what
we use to show the object properties.

This is pretty cool :^)

64f16c141d Terminal: Implement basic history scrollback 
This code needs some optimization work to reduce the amount of repaints
but the history feature basically works, which is cool :^)

462336ed49 LibVT: Add scrollback history to VT::Terminal 
The default (hard-coded) history size is 500 lines. When the history is
altered, the TerminalClient is notified via terminal_history_changed().

a5cdd0afa5 NonnullPtrVector: Add ptr_at() getters for accessing the NonnullPtr 
Normally you want to access the T&, but sometimes you need to grab at
the NonnullPtr, for example when moving it out of the Vector before
a call to remove(). This is generally a weird pattern, but I don't have
a better solution at the moment.

6cd9c020ea LibC: Write to the dbg() every time we perror() in userspace 
There's a high chance that we're interested in whatever errors come out
of perror(), so let's output those on the debugger as well.

filename when it prints a line.

c2213449c0 LibCore: Move CObject serialization into CObject::save_to(JsonObject&) 
The idea is for subclasses to override this and add whatever properties
are relevant for them, then call up to their base class, etc.

7038935f74 GraphicsBitmap: create_wrapper() should take pitch as a parameter 
We shouldn't assume that the pitch of some arbitrary bitmap memory that
we're wrapping is going to be 16-byte aligned. Instead, just take the
pitch as a parameter.

Also update WindowServer to pass the pitch to the framebuffer bitmaps.

d11d847161 WindowServer: Fix an assertion 
Now that the window used by a WSMenu is its child CObject, the menu also
receives CChildEvent's about the window, including CEvent::ChildAdded when
the window gets created. At this point, menu_window() still returns nullptr,
so stop unconditionally assuming that it doesn't. We should not care whether
or not we have a window for unrelated events anyway.
