Gabriele Svelto 16e08520e6 Add support for parsing the DW_AT_ranges attributes
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.

BUG=754

erikchen@chromium.org 7bebb27fb4 Fix some fragile code that is likely to cause future memory corruption
problems.

- The ordering of keys in stl containers cannot change. Make the relevant
members const to guarantee this assumption.
- Add handling and logging for demangle errors.
- Fix a potential double-delete bug if a function passed to AddFunction() is
already present.

ted.mielczarek 3ca4a120de Add some unit tests for Linux WriteSymbolFile
This patch adds synth_elf::{StringTable,SymbolTable,ELF} classes to
produce in-memory ELF files to properly test the Linux symbol dumping
code. It also uses those classes to add some basic tests for
the WriteSymbolFile function.

ted.mielczarek bf25801d83 Put PUBLIC lines in Mac symbol files.
Exported symbols on Mach-O binaries are defined in a STABS section. This patch makes stabs_reader handle them, adds support for Extern symbols in the Module class (which are output as PUBLIC lines in symbol files), and the proper processing in stabs_to_module to hook it all up.

jimblandy deb500f6c8 Breakpad STABS reader: Properly compute function end addresses.
An N_FUN stabs with no name is an explicit end-of-function marker, whose
value is the size of the function. This patch changes the stabs reader to
recognize these and use them to compute the function's ending address,
instead of treating them as functions with no names and mysterious
addresses. It also adds appropriate unit tests.

jimblandy b28be1254c Breakpad Linux dumper: Rename DumpStabsHandler to StabsToModule.
All the other classes which receive debugging data from some sort of parser
and use it to populate a Module have names ending in "ToModule":
DwarfCUToModule, DwarfCFIToModule. Also, DumpStabsHandler doesn't actually
dump anything.

This patch renames the DumpStabsHandler class to StabsToModule, which is
more consistent and descriptive.
