Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header.

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information.

LibGUI: Fix broken doubleclick detection due to uninitialized GElapsedTimer.

#include <AK/Assertions.h>
Kernel: Fix timeout support in select The scheduler expects m_select_timeout to act as a deadline. That is, it should contain the time that a task should wake at -- but we were directly copying the time from userspace, which meant that it always returned virtually immediately. At the same time, fix CEventLoop to not rely on the broken select behavior by subtracting the current time from the time of the nearest timer.

LibCore: Remove leading C from filenames

LibGUI: Add GWidget::doubleclick_event(). Now double-clicking an item in a GTableView or GItemView will activate it.

LibCore: Put all classes in the Core namespace and remove the leading C I've been wanting to do this for a long time. It's time we start being consistent about how this stuff works. The new convention is: - "LibFoo" is a userspace library that provides the "Foo" namespace. That's it :^) This was pretty tedious to convert and I didn't even start on LibGUI yet. But it's coming up next.

RequestServer: Handle IPC requests on multiple threads concurrently Previously RS handled all the requests in an event loop, leading to issues with connections being started in the middle of other connections being started (and potentially blowing up the stack), ultimately causing requests to be delayed because of other requests. This commit reworks the way we handle these (specifically starting connections) by first serialising the requests, and then performing them in multiple threads concurrently; which yields a significant loading performance and reliability increase.
