Breakpad Linux dumper: Add support for dumping DWARF CFI as STACK CFI records.

Browse source 
Define a new DWARF parser class, dwarf2reader::CallFrameInfo.

Extend google_breakpad::Module to store and write out 'STACK CFI' records.

Define a new google_breakpad::DwarfCFIToModule class, to accept DWARF
CFI data from the parser and populate a Module with the equivalent
STACK CFI records.

Extend the Linux symbol dumping tool, dump_syms, to use
dwarf2reader::CallFrameInfo, google_breakpad::DwarfCFIToModule, and
google_breakpad::Module to extract DWARF CFI from the executable or
shared library files and write it to the Breakpad symbol file.

Define CFISection, a new class derived from TestAssembler::Section,
for use in creating DWARF CFI data for test cases.
