827e375297 LibELF: Validate the mapped file in DynamicLoader constructor 
ELF::DynamicLoader now validates the ELF header and the program headers
in its constructor. The requested program interpreter from the
PT_INTERP program header is now avaiable via a getter. The dynamic
loader program will want to check that this matches its name, for extra
shenanigans checking.

61acca223f LibELF: Move validation methods to their own file 
These validate_elf_* methods really had no business being static
methods of ELF::Image. Now that the ELF namespace exists, it makes
sense to just move them to be free functions in the namespace.

21b5909dc6 LibELF: Move ELF classes into namespace ELF 
This is for consistency with other namespace changes that were made
a while back to the other libraries :)

8dd96ad143 ProfileViewer: Color code the instruction rows by sample percentage 
We now "heat color" the instruction-level samples so you can get a nice
visual picture of where time is spent in functions. :^)

a4006e19d7 ProfileViewer: Don't skip the innermost frame when loading profiles 
We were skipping the innermost frame as a workaround for the kernel
putting garbage data there. Now that the kernel puts the instruction
poiner there, we can load the frame normally! :^)

b7ff3b5ad1 Kernel: Include the current instruction pointer in profile samples 
We were missing the innermost instruction pointer when sampling.
This makes the instruction-level profile info a lot cooler! :^)

69583f07e0 ProfileViewer: Add an instruction-level sample viewer 
When you select a function in the profile tree, we will now display
a per-instruction breakdown of aggregated samples in that function.

This allows us to look much closer at what our code is doing! :^)

54fc972a72 MenuApplets: Support memory usage and custom colors in ResourceGraph 
The ResourceGraph menu applet now supports a few command line options:

--cpu / -C to display a CPU usage graph
--memory / -M to display a memory usage graph
--name / -n to set a name which is used to order applets
--color / -c to set the graph color (supports anything
Gfx::Color::from_string() understands)

The SystemServer.ini and WindowServer.ini config files have been updated
to spawn and show two ResourceGraph menu applets, one for CPU usage
(green) and one for memory usage (cyan) - this matches the colors in the
SystemMonitor graphs.

b46a8d7335 MenuApplets: Rename CPUGraph to ResourceGraph 
The plan is to extend what currently is known as "CPUGraph" and let the
SystemServer spawn multiple instances of it - which then can show memory
or network usages as well :^)

Simply renaming the applet is the first step.
