TNeo: real-time kernel initially based on TNKernel

• TNKernel: copyright 2004, 2013 Yuri Tiomkin.
• PIC32-specific routines: copyright 2013, 2014 Anders Montonen.
• TNeo: copyright 2014 Dmitry Frank.

TNeo was born as a thorough review and re-implementation of TNKernel. The new kernel has well-formed code, inherited bugs are fixed as well as new features being added, and it is tested carefully with unit-tests.

API is changed somewhat, so it's not 100% compatible with TNKernel, hence the new name: TNeo.
