This enables the DWARF reader to properly parse DW_AT_ranges attributes
in compilation units and functions. Code covered by a function is now
represented by a vector of ranges instead of a single contiguous range
and DW_AT_ranges entries are used to populate it. All the code and tests
that assumed functions to be contiguous entities has been updated to
reflect the change. DW_AT_ranges attributes found in compilation units
are parsed but no data is generated for them as it is not currently needed.

We've gotten mixed advice from the lawyery types about whether this
matters. But it's easy enough to do.

Breakpad's DWARF line number info parser provides a code address,
file, and line number for each code/source pairing, but doesn't
provide the length of the machine code. This makes that change, as
discussed in the following thread:
http://groups.google.com/group/google-breakpad-dev/browse_thread/thread/ed8d2fde79319368p
This patch also makes the corresponding changes to the functioninfo.cc
module, used by the Mac dumper. This patch has no effect on the Mac
dumper's output.

Add a new member function to dwarf2reader::Dwarf2Handler,
ProcessAttributeReference, for reporting attribute values that are
references to other DIEs. This handler member function always receives
an absolute offset (that is, relative to the start of the .debug_info
section, not to the start of the compilation unit), regardless of the
form the attribute uses. (Some forms are CU-relative, some are
absolute.)

Move the DWARF parser, and the functioninfo.cc DWARF consumer, from
src/common/mac/dwarf to src/commmon/dwarf, so that it can be shared
between the Mac and Linux dumpers.
Fix up #include directives, multiple inclusion protection macros, and
Xcode build files.
