Jiaming Yuan 5d7cdf2e36 [Breaking] Rename Quantile DMatrix C API. (#7082) 
The role of ProxyDMatrix is going beyond what it was designed.  Now it's used by both
QuantileDeviceDMatrix and inplace prediction.  After the refactoring of sparse DMatrix it
will also be used for external memory.  Renaming the C API to extract it from
QuantileDeviceDMatrix.

Jiaming Yuan 689eb8f620 Check external memory support for exact tree method. (#7088) 2021-07-08 02:12:57 +08:00
Jiaming Yuan 615ab2b03e Extract evaluate splits from CPU hist. (#7079) 
Other than modularizing the split evaluation function, this PR also removes some more functions including `InitNewNodes` and `BuildNodeStats` among some other unused variables.  Also, scattered code like setting leaf weights is grouped into the split evaluator and `NodeEntry` is simplified and made private.  Another subtle difference with the original implementation is that the modified code doesn't call `tree[nidx].Parent()` to traversal upward.

Jeff H d22b293f2f Update reference to treelite website (#7084) 
treelite.io is no longer a valid site and re-directs users to a parked domain. Re-directing to the documentation is safer at this point.
