Ethernet configuration fix, improve PinManager (#2123)

* Improved pin manager, ethernet config

* Ethernet is configured prior even to LED pins
* Pin Manager allocation / deallocation functions
   now take an "ownership" tag parameter, helping
   avoid accidentally free'ing pins that were allocated
   by other code
* Pin Manager now has ability to allocate multiple
  pins at once; Simplifies error handling

* Fix operator precedence error

Bitwise AND has lower precedence than the
relational "greater than" operator.

* PinManager update for some user modules

* don't build everything...

* Final step to reduce RAM overhead

* update comment

* remove macros

* Remove leftover allocated

* Init ethernet after settings saved
