Better tie together ContentType and Permissions.
...
Since most content types (e.g. typeCode) have a
preferred Permission, add a function to do that mapping.
Then hook up to YAML Reader and Writer such that
the 'permissions:' key does not need to be specified unless
overriding what the content type prefers.

Add first linker pass (StubsPass) which looks for calls to shared library
symbols and replaces them with calls to a StubAtom. On ELF system, a "stub"
is a PLT entry. Added a simple test case.
Pass a Platform object to YAML reader and writer for converting fixup kinds
between names and values.
Change output of Resolver to be a File object instead of a vector of Atoms.
Thus, passes operate on a File instead of just Atoms.
Rework how to walk through a File's Atoms. Now iterator based instead of
a method that visits each atom.

First chunk of native object file reader/writer. The lld-core tool now reads YAML file, links, writes that out as native object format, then reads that native file, then writes the YAML to stdout. Thus the test suite tests both YAML reading/writing as well as native object file reading/writing.
