Jonathan Schwender 1632e61ed6 servoshell: Rename executable to servoshell. (#42958)
This should help clarify the difference between servo the library /
engine and servoshell the browser (demo).

Other changes: 

- Removed etc/servo.sb ( [apple sandbox profile
format](https://angelica.gitbook.io/hacktricks/macos-hardening/macos-security-and-privilege-escalation/macos-security-protections/macos-sandbox#sandbox-profiles))
since it is not needed anymore. See [this
comment](https://github.com/servo/servo/pull/42958#discussion_r2876253489)
for more details.

Testing: This is a very invasive change, and there are bound to be
scripts / places I have overlooked. Searching for usages of `servo` is
very hard, since it's also the name of the library.

The power and performance measurement for Servo parallel browser

This script uses PowerMetrics to measure power usage of Servo on OS X

Running

cd servo/tests/power
sudo python PowerMeasure.py

You can define the maximum number of threads in layout level, rendering by cpu, benchmarks and output directory with these command line arguments:

  • -b BENCHMARK, --benchmark BENCHMARK sets the benchmark, for example '-B "perf-rainbow.html"'
  • -c CPU, --CPU CPU renders with CPU instead of GPU
  • -l LAYOUTTHREADS, --LayoutThreads LAYOUTTHREADS sets the maximum number of threads for layout, for example " -L 5"
  • -o OUTPUT, --Output OUTPUT specifyes the output directory

Example

This command will measure power and performance for 1 to 5 threads in layout with CPU rendering when we are running the about-mozilla.html benchmark

sudo python PowerMeasure.py -L 5 -c cpu -b "/Desktop/servo/src/test/html/about-mozilla.html" -o /Desktop/Results/
