dev-manual, ref-manual, yocto-project-qs: Updates to parallelism variables
The way the old manual set had worded the use of the
BB_NUMBER_THREADS, PARALLEL_MAKE, and BB_NUMBER_PARSE_THREADS
had become depricated. It suggested a lot of user intervention
to get these variables set to have the build system utilize
optimal parallelism. The change a while back to the build system
where the variables are set to the number of build host cores
now makes the variables automatically be set to their best
values. I have gone through the manual set and changed wordings
appropriately to reflect this.
