[Toaster] TRDEPENDS, TRRECOMENDS vs RDEPENDS, RRECOMENDS

[Damian, Alexandru]

Hi,

This is an artifact of how data is collected.

TRDEPENDS and TRECOMMENDS are just RDEPENDS and RRECOMMENDS collected at
target creation time, instead of package build time.

What may happen is that for a target we use packages that were not built
during the current build, but either in a previous build or reused from
sstate cache.
Thus we collect the package information two times: once when the package is
build, and once when the package is installed on the target.
Note that these two sets may not be identical, as on target install we
collect data for a different set of packages that what was actually built
during the current run.

I suggest that in "target install packages" page we show the T*
dependencies, and in the "build packages" page we should the non-T
dependencies.

Hope this helps,
Alex
