f98a18acb7 [PECOFF] Refactor module-defintion file parser. 
Refactor the parser so that the parser can return arbitrary type of parse
result other than a vector of ExportDesc. Parsers for non-EXPORTS directives
will be implemented in different patches. No functionality change.

6edd722a2c [mach-o] enable mach-o and native yaml to be intermixed 
The main goal of this patch is to allow "mach-o encoded as yaml" and "native
encoded as yaml" documents to be intermixed.  They are distinguished via 
yaml tags at the start of the document.  This will enable all mach-o test cases
to be written using yaml instead of checking in object files.

The Registry was extend to allow yaml tag handlers to be registered.  The
mach-o Reader adds a yaml tag handler for the tag "!mach-o". 

Additionally, this patch fixes some buffer ownership issues.  When parsing
mach-o binaries, the mach-o atoms can have pointers back into the memory 
mapped .o file.  But with yaml encoded mach-o, name and content are ephemeral, 
so a copyRefs parameter was added to cause the mach-o atoms to make their
own copy.

8b14d14209 [PECOFF] Support module-definition file. 
Module-definition (.def) files are the file containing linker directives,
such as export symbols. Because link.exe supports the same features as command
line options, just as some Linker Script commands overlaps with command line
options, use of module-definition file is not really necessary. It provides
an alternative way to specify some linker options.

This patch implements EXPORTS directive. Other directives will be implemented
in the future.
