a5f879ea8c Base: Add a man page documenting security mitigations 
Since so much work is being put into mitigations, I thought
it would be nice to track them all in one place. This is the
start of that document.

ca1c560161 Base: Don't mark "prot_exec" pledge promise as a SerenityOS extension 
OpenBSD also has this promise.

c94392a1cc Applications: Remove "Welcome" application 
This was a cute application for its time, but it's far too jokey and
non-serious for how I'd like this project to treat itself.

6e4e3a7612 Kernel: Remove pledge exception for sys$getsockopt() with SO_PEERCRED 
We had an exception that allowed SOL_SOCKET + SO_PEERCRED on local
socket to support LibIPC's PID exchange mechanism. This is no longer
needed so let's just remove the exception.

90343eeaeb Revert "Kernel: Return -ENOTDIR for non-directory mount target" 
This reverts commit b7b09470ca.

Mounting a file on top of a file is a valid thing we support.

d0c5979d96 Kernel: Add "prot_exec" pledge promise and require it for PROT_EXEC 
This prevents sys$mmap() and sys$mprotect() from creating executable
memory mappings in pledged programs that don't have this promise.

Note that the dynamic loader runs before pledging happens, so it's
unaffected by this.

dbbc378fb2 Kernel: Return -ENOTBLK for non-block device Ext2FS mount source 
When mounting an Ext2FS, a block device source is required. All other
filesystem types are unaffected, as most of them ignore the source file
descriptor anyway.

Fixes #5153.

b7b09470ca Kernel: Return -ENOTDIR for non-directory mount target 
The absence of this check allowed silly things like this:

    # touch file
    # mount /dev/hda file

bf0719092f Kernel+Userland: Remove shared buffers (shbufs) 
All users of this mechanism have been switched to anonymous files and
passing file descriptors with sendfd()/recvfd().

Shbufs got us where we are today, but it's time we say good-bye to them
and welcome a much more idiomatic replacement. :^)

f03800cee3 Kernel: Add dedicated "ptrace" pledge promise 
The vast majority of programs don't ever need to use sys$ptrace(),
and it seems like a high-value system call to prevent a compromised
process from using.

This patch moves sys$ptrace() from the "proc" promise to its own,
new "ptrace" promise and updates the affected apps.

5e5eb615ec Shell: Add runtime errors and implement break/continue 
Such errors are raised when SyntaxError nodes are executed, and are also
used for internal control flow.
The 'break' and 'continue' commands are currently only allowed inside
for loops, and outside function bodies.

This also adds a 'loop' keyword for infinite loops.

b2316701a8 Everywhere: void arguments to C functions 
Problem:
- C functions with no arguments require a single `void` in the argument list.

Solution:
- Put the `void` in the argument list of functions in C header files.

Everywhere: Switch from (void) to [[maybe_unused]] (#4473) 
Problem:
- `(void)` simply casts the expression to void. This is understood to
  indicate that it is ignored, but this is really a compiler trick to
  get the compiler to not generate a warning.

Solution:
- Use the `[[maybe_unused]]` attribute to indicate the value is unused.

Note:
- Functions taking a `(void)` argument list have also been changed to
  `()` because this is not needed and shows up in the same grep
  command.
