[yocto] Size of Packages from bitbake build feature idea

[nick]

Greetings All,

I assume this is possibly already there or is in another tool used by most people
here. However if not I was wondering if it's a good idea to add support for telling
what packages use up the most space on the root filesystem before the build or even
a good idea. 

Something like bitbake show package size can be very useful for trimming down your
packages before the build is done or even before debugging storage requirements. It
should also support telling what shared libraries are used by each package.
