[PATCH 2/2] docs: improve ordering and remove old header titles

[Harry van Haaren]

Move the "source_org" page to after overview, where it fits
better to explain the source-code layout of DPDK, before getting
into details of specific libraries such as EAL.

Also removes the older titles from the 3 documents which still had them.
