Breakpad DWARF parser: Add support for parsing .eh_frame encoded pointers.

Browse source 
The Linux C++ exception handling data format (.eh_frame) can specify a
number of different encodings for the addresses it contains. This
patch extends dwarf2reader::ByteReader to read pointers encoded in
these ways.
