d9dd934f8c Change Parse trait implementers to shorten/rename utils::read_* imports to just the method names 
This declutters the code a bit. It's obvious what these methods are doing and
its not important to state which module they're defined in on each invocation.

9aab0d1096 Add simple Parse trait 
My plan is to make the various ELF data structures implement this Parse trait which knows
how to parse that structure based on the given endianness and data width (32- or 64-bit).

f9d4b29ea9 Remove unnecessary macro_use from utils 
It no longer implements any macros
Also, remove the pub on mod utils, since it's only needed internally and shouldn't be considered part of the public interface

4db2b9065e Split Generic System V Application Binary Interface ELF File Header constants out into gabi.rs 
This patch starts changing the type representations for our ELF types. It splits out the raw constants defined in
the Generic System V Application Binary Interface out into its own file (gabi.rs) as native type constants. The
type definitions in types.rs are now left to be higher level semantic representations of these fields which may
or may not directly map to the on-disk ELF data layout.

The intent here is to structure the code such that the opinionated rust representation of these parsed ELF structures
live separately from the official gabi definitions. This could set us up for a future where consumers of this library that
desire their own different rust representations of parsed ELF structures to consume the gabi definitions without
also having to much about with our representations here.

a81e7e7b54 Remove the read_u8!() macro 
The read_u8!() macro is unnecessary since there are not endianness
considers reading a u8. Additionally, the macro is broken because it
tries to specialize the read_u8 function in the ReadBytesExt trait
for LittleEndian and BigEndian which is not supported by that API.
