5fcd34b810 Userland: Add an "adjtime" utility 
It's a thin userland wrapper around adjtime(2). It can be used
to view current pending time adjustments, and root can use it to
smoothly adjust the system time.

As far as I can tell, other systems don't have a userland utility
for this, but it seems useful. Useful enough that I'm adding it to
the lagom build so I can use it on my linux box too :)

8b76a1e548 js: Remove test mode 
Now that we have a standalone test-js program, the "-t" test mode of the
js REPL is unused and can simply be removed. Required functionality has
been duplicated in test-js (isStrictMode function, loading of testing
utilities).

Also remove outdated information about tests from the js(1) man page.

4fa7146da1 Base: Move the modload and modunload command documentation to man8 
These are system administration commands, not intended for use by
all users. These tend to go in section 8.

38f93ef13b Kernel: Disable x86 RDTSC instruction in userspace 
It's still possible to read the TSC via the read_tsc() syscall, but we
will now clear some of the bottom bits for unprivileged users.

f598bbbb1d Kernel: Prevent executing I/O instructions in userspace 
All threads were running with iomapbase=0 in their TSS, which the CPU
interprets as "there's an I/O permission bitmap starting at offset 0
into my TSS".

Because of that, any bits that were 1 inside the TSS would allow the
thread to execute I/O instructions on the port with that bit index.

Fix this by always setting the iomapbase to sizeof(TSS32), and also
setting the TSS descriptor's limit to sizeof(TSS32), effectively making
the I/O permissions bitmap zero-length.

This should make it no longer possible to do I/O from userspace. :^)

9c0836ce97 Kernel: Enable x86 UMIP (User Mode Instruction Prevention) if supported 
This prevents code running outside of kernel mode from using the
following instructions:

* SGDT - Store Global Descriptor Table
* SIDT - Store Interrupt Descriptor Table
* SLDT - Store Local Descriptor Table
* SMSW - Store Machine Status Word
* STR - Store Task Register

There's no need for userspace to be able to use these instructions so
let's just disable them to prevent information leakage.

d0f9906c17 Crash: Add a "Test All Crash Types" option 
Add an option "-A", that will run all of the crash types in the crash
program. In this mode, all crash tests are run in a child process so
that the crash program does not crash.

Crash uses the return status of the child process to ascertain whether
the crash happened as expected.
