LibMain is dynamically linked in every binary. This results in a
slightly slower load time. In the past people have pegged this at 0.7
ms on some hardware.
This change makes it statically linked and eliminates 0.6 ms of
run-time on my machine. This is tested by running a script which just
executed `/bin/true` in a loop 10,000 times. Before this patch it
reliably executed in ~90,000 ms. After this patch it is ~84,000
ms. This is a speed up of 6,000 ms over 10,000 executions, or 0.6 ms
per execution.
By linking with LibMain, your program no longer needs to provide main().
Instead, execution begins in this function:
ErrorOr<int> serenity_main(Main::Arguments);
This allows programs that link with LibMain to use TRY() already in
their entry function, without having to do manual ErrorOr unwrapping.
This is very experimental, but it seems like a nice idea so let's try it
out. :^)
