docs, parallelism: Rearrange how jobserver reservations are made
Rasmus correctly observed that the existing jobserver reservation only
worked if no other build targets were specified. The correct approach
is to hold the jobserver slots until sphinx has finished. To fix this,
the following changes are made:
- refactor (and rename) scripts/jobserver-exec to set an environment
variable for the maximally reserved jobserver slots and exec a
child, to release the slots on exit.
- create Documentation/scripts/parallel-wrapper.sh which examines both
$PARALLELISM and the detected "-jauto" logic from Documentation/Makefile
to decide sphinx's final -j argument.
- chain these together in Documentation/Makefile
