-  Process "qXfer:object:read:annex:offset,length" request.
-
-  Returns an XML document that contains loaded libraries. In our case it is
-  infomration in the EFI Debug Inmage Table converted into an XML document.
-
-  GDB will call with an arbitrary length (it can't know the real length and
-  will reply with chunks of XML that are easy for us to deal with. Gdb will
-  keep calling until we say we are done. XML doc looks like:
-
-  <library-list>
-    <library name="/a/a/c/d.dSYM"><segment address="0x10000000"/></library>
-    <library name="/a/m/e/e.pdb"><segment address="0x20000000"/></library>

-  Since we can not allocate memory in interupt context this module has
-  assumptions about how it will get called:
-  1) Length will generally be max remote packet size (big enough)
-  2) First Offset of an XML document read needs to be 0
-  3) This code will return back small chunks of the XML document on every read.
-     Each subseqent call will ask for the next available part of the document.
-
-  Note: The only variable size element in the XML is:
-  "  <library name=\"%s\"><segment address=\"%p\"/></library>\n" and it is
-  based on the file path and name of the symbol file. If the symbol file name
-  is bigger than the max gdb remote packet size we could update this code
-  to respond back in chunks.
