pkg5 module - Speed up installing lists of packages (Check for all packages at once)

[danowar2k]

SUMMARY

As of right now, pkg5 processes a list of packages to install by filtering the packages by checking for each package if it is installed.

I measured the time it takes checking ten packages doing it this way. On my system it was 5 seconds.
I then measured the time it takes checking once for all ten packages, which was below 1 second.

I propose to change the way the pkg5 module checks when installing packages. I'll add a pull request for this later.

COMPONENT NAME

pkg5

ADDITIONAL INFORMATION

This would greatly speed up the installation of multiple packages (the more packages the faster it is)
