Split in subprojects

[piranna]

Gaia got to be a bigger project that i thought, so it needs to be splited in several subprojects and also integrate with PyMite4Multiboot modifications. This subprojects should be:

• libGaia: library to easy to setup the boot process of an operating system from scratch (bootloader)
• GaiaLib: C standard lib focused on port desktop standard apps to run on baremetal hardware

To do this, the ideal route should be:

• libGaia
  • remove all inline assembly code and put it inside assembler folder
  • move assembler folder inside the library
  • split libGaia as an independent project
• GaiaLib
  • add backends support for GaiaLib, being the first one the Gaia backend (obviously...)
  • add to GaiaLib a backend for kernel_native for modifications done on PyMite4Multiboot, being this the new native one
