- added more header validity checks
- create section name retrieval

This resolves an issue where km_init would fail to find the memory
property if it was not the first node that it looked at.

The ELF parser needs more work, there are more structs to be added.
memcpy was refactored from mem.h into common.h
endianness conversions were standardized in types.h

- fixed an edge case in `kmalloc` where the broken block from a split
may be too small to accomodate another `struct page`. this was fixed
such that if we do not have enough room to allocate another `struct
page` then `kmalloc` simply returns the entire page.
- fixed empty and single-element `free_list` edge cases in `kfree`

the parent commit (b106df2447d23d6b3fcffa7cc87edde218d054f3) discussed
the possibility of creating dtb device discovery. for that, we have
replaced wdt device discovery with dtb device discovery. in the future,
we will use the pci kernel module to use device discovery via a PCI
controller
|
|
discuss: per wrv32em status, consider moving custom wdt format to dtb or
pci device discovery (potentially both: we have the framework for pci.ko
extension after using dtb to discover memory and pci devices)
