[internals refactor] docs and reorganize compilation units

[majestrate]

begin piecewise refactor

rearrange compilation units in cmake to have unambiguous component separation, with documentation notes on what the responsibilities of each are.

the new library structure:

• creates lokinet-base interface library that sets up common include paths and compile flags
• makes lokinet-amalgum an interface library with everything in it.
• marks the lokinet-service-deprecated-kitchensink component (the thing we are splitting up)
• defines the desired component layout going forward, adds stub libraries but no code or headers
• very brief documentation of component relations

to get the refactor smaller a few concessions have been made:

• have all our headers be referenced in a consistent albeit dumb way (consistency is preferred)

these commits in order are:

1) adding high level plan docs 2) redoing header conversion 3) cmake restructure 4) clang format comment
