Allow everything to be built from the top level directory with just
'make', cleaned with 'make clean', and installed with 'make
install'. Also support these in any particular subdirectory.
Specifying 'make VERBOSE=1' will print each ld/g++/etc. command as
it runs.
Kernel and early host tools (IPCCompiler, etc.) are built as
object.host.o so that they don't conflict with other things built
with the cross-compiler.
When we're in a drag, we're no longer concerned with streaming mouse
events to the window that initiated the drag, so just clear the active
input window pointer.
This fixes an issue where you'd have to click once after drag and drop
in order to "release" the mouse from the active input window.
We now try to open image files dropped on us from FileManager. :^)
The QuickShow code is not exactly well-factored, and should be fixes up
to not do the same thing twice, etc.
These fields are intended to carry the real meat of a drag operation,
and the "text" is just for what we show on screen (alongside the cursor
during the actual drag.)
The data field is just a String for now, but in the future we should
make it something more flexible.
Toolchain build makes git repo out of toolchain to allow patching

Parameterize BuildIt with default TARGET of i686 but arm is experimental
While setting up the main thread stack for a new process, we'd incur
some zero-fill page faults. This was to be expected, since we allocate
a huge stack but lazily populate it with physical pages.
The problem is that page fault handlers may enable interrupts in order
to grab a VMObject lock (or to page in from an inode.)
During exec(), a process is reorganizing itself and will be in a very
unrunnable state if the scheduler should interrupt it and then later
ask it to run again. Which is exactly what happens if the process gets
pre-empted while the new stack's zero-fill page fault grabs the lock.
This patch fixes the issue by creating new main thread stacks before
disabling interrupts and going into the critical part of exec().
Now that Frame knows the visible viewport rect, it can easily ignore
repaint requests from e.g <blink> elements that are not currently
scrolled into view. :^)
When the visible viewport rect changes, we walk the layout tree and
check where each LayoutImage is in relation to the viewport rect.
Images outside have their bitmaps marked as volatile.
Note that the bitmaps are managed by ImageDecoder objects. If a bitmap
is purged by the kernel while volatile, we construct a new ImageDecoder
next time we need pixels for the image.
Pushing the TAB key in the shell now prints suggestions to terminal.
This makes it easier to the user to actually see what files are
available before executing the command they currently have typed.
The "Invert tree" checkbox was accidentally defaulted to display true when the actual tree wasn't being inverted, causing the checkbox to say the opposite of the tree state initially. This change just brings the visual indicator in line with what the code is actually doing.
Inverting the tree turns all of the innermost stack frames into roots,
allowing them to accumulate their total sample counts with other
instances of the same frame being innermost. This is an essential
feature of any cool profiler, and now we have it. :^)
A client that only ever does synchronous IPC calls from its side would
never actually process incoming asynchronous messages since they would
arrive while waiting for a synchronous response and then end up sitting
forever in the "unhandled messages" queue.
We now always handle unhandled messages using a deferred invocation.
This fixes the bug where Audio.MenuApplet didn't learn that the muted
state changed in response to its own request to change it. :^)
