35ba4bf005 TTY: Reset VGA start row when setting graphical TTY 
This was causing the screen (on a real machine) to be split in half.

a7dbb3cf96 Kernel: Use a FixedArray for a process's extra GIDs 
There's not really enough of these to justify using a HashTable.

e0ecfc0c92 LibC: Statically allocate allocators

two physical pages for them in each process :^)

4b16ac0034 Kernel: Purging a page should point it back to the shared zero page 
Anonymous VM objects should never have null entries in their physical
page list. Instead, "empty" or untouched pages should refer to the
shared zero page.

Fixes #1237.

0bb4111735 HackStudio: Unbreak the form editor's widget icons

2060da829c WindowServer: Remove unveils of /bin and /etc/passwd

a008e2f63a WindowServer: Drop the "exec" pledge promise entirely 
Now that the system menu is out-of-process, we no longer need to exec()
from WindowServer, allowing us to drop this promise. Very cool!

84520d8b59 WindowServer: Make way for the out-of-process system menu 
This patch removes the internal system menu from WindowServer and
replaces it with two IPC API's:

    SetSystemMenu(menu_id)
    SetSystemTheme(theme_path, theme_name)

These API's will allow us to complete the SystemMenu program and
move it entirely out of process.

189fa68c0b LibGUI: Expose GUI::Menu::menu_id() and also allow forced realization 
Menu realization is when we instruct WindowServer to create the
server-side menu objects on our behalf.

7afd9039d1 Base: Add a Minesweeper app icon that's actually 16x16 
The one we were using was actually 15x15 which tripped up an assertion
when loading it into a menu using the GUI::Action code path.

Andreas Kling
737e455cbc SystemMenu: Add a separate program to host the system menu 
This will allow us to run the system menu as any user. It will also
enable further lockdown of the WindowServer process since it should no
longer need to pledge proc and exec. :^)

Note that this program is not finished yet.

Work towards #1231.

a0ad372b08 AudioServer: Remove ASEventLoop class and do all the setup in main() 
This class was too small and unnecessary.

6eccd166ed SystemDialog: Use Yes/No dialog instead of OK/Cancel 
This also removes some unecessary debug lines. (The debug lines are
unnecessary because LibGUI already outputs the debug information, so
SystemDialog just doubled it up.)

48f7c28a5c Kernel: Replace "current" with Thread::current and Process::current 
Suggested by Sergey. The currently running Thread and Process are now
Thread::current and Process::current respectively. :^)

4f4af24b9d Kernel: Tear down process address space during finalization 
Process teardown is divided into two main stages: finalize and reap.

Finalization happens in the "Finalizer" kernel and runs with interrupts
enabled, allowing destructors to take locks, etc.

Reaping happens either in sys$waitid() or in the scheduler for orphans.

The more work we can do in finalization, the better, since it's fully
pre-emptible and reduces the amount of time the system runs without
interrupts enabled.

0e33f53cf8 Kernel: Allow multiple inspectors of a process (in /proc) 
Replace Process::m_being_inspected with an inspector reference count.
This prevents an assertion from firing when inspecting the same process
in /proc from multiple processes at the same time.

It was trivially reproducible by opening multiple FileManagers.

a78bc5e6fc LibGUI: Generate NotificationServer IPC messages during build 
I hacked this to skip using flock since NotificationServer and LibGUI
depend on each other. There's probably a better solution.

7efb497837 NotificationServer: Add new notification windows below the lowest one 
Don't stack notifications on top of each other, instead put them below
one another on the y axis.

This will obviously break if the screen fills with notifications, but
that's a FIXME for now. :^)
