If a DNS server responds with multiple answers for a question, we will
get a newline-separated sequence of answers from LookupServer.
However, we don't handle this properly yet in LibC, so just split the
response by line and only care about the first answer for now.
We should rename all of these functions to match the real VT100 names.
This will make it 100% easier to work on LibVT.

The curious "stomp" state occurs when you type your way all the way
over to the right side of the terminal buffer, and we "stomp" once on
the very last column, before jumping to the next line.
We should never go into "stomp" state in response to programmatically
setting the cursor position. This fixes a small artifact in vttest.
To allow for more asynchronous teardown of IClientConnection, make the
post_message() function simply return if called after the IPC socket
has been closed.
This changes copyright holder to myself for the source code files that I've
created or have (almost) completely rewritten. Not included are the files
that were significantly changed by others even though it was me who originally
created them (think HtmlView), or the many other files I've contributed code to.
Previously it was created the first time you requested a context menu
for the GTextEditor by right-clicking in it.
That meant it wasn't possible to use Ctrl+L to "go to line" before you
had first right-clicked the editor.
It's useful for the GTextDocument to have access to the initiating
GTextEditor widget during the initial execution of a command.
Since commands are executed via calls to GUndoCommand::redo(), we do
this by wrapping the invocation of redo() in a new helper called
GTextDocumentUndoCommand::execute_from(GTextDocument::Client).
This is then used to fetch the current auto-indentation feature state
and the soft tab width, both used by text insertion.
Now that String::split() defaults to keep_empty=false, we need to make
sure the pwd and grp functions in LibC keep the empty ones.
This fixes "id" moaning about invalid lines in /etc/group.
GModel subclasses can now override drag_data_type() to specify which type
GAbstractView should set for drag data. The default implementation returns a
null string, which disables dragging from this widget.
It's now an abstract (pure virtual) public method in GAbstractView that
individual widgets have to implement. This will allow us to move more
selection-related logic into GAbstractView in order to share it between
implementations.
The "stay_within" parameter to CObject::dispatch_event() optionally
specifies a node in the CObject parent chain where event dispatch
should stop bubbling upwards.
Since event dispatch is done recursively, this was not working right,
as we would simply return from the innermost dispatch loop, leaving
the event un-accepted, which meant that the penultimately inner
dispatch loop would pick up the event and keep bubbling it anyway.
This made it possible for events to jump across window boundaries
within an application, in cases where one window was a CObject ancestor
of another window. This is typically the case with dialog windows.
Fix#1078.
A process has one of three veil states:
- None: unveil() has never been called.
- Dropped: unveil() has been called, and can be called again.
- Locked: unveil() has been called, and cannot be called again.
Sergey suggested that having a non-zero O_RDONLY would make some things
less confusing, and it seems like he's right about that.
We can now easily check read/write permissions separately instead of
dancing around with the bits.
This patch also fixes unveil() validation for O_RDWR which previously
forgot to check for "r" permission.
