Breakpad DWARF Reader: Change LineInfoHandler::AddLine to provide the line's length.

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.
