Reduce duplication of code by
* Removing from elf_common.h definitions available in os/kernel/elf.h
* Deleting elf32.h and elf64.h
* Renaming elf_common.h to elf_private.h
* Updating source to build using public and private ELF header files
together

- Add FindSection() and IsLoaded() calls to ElfFile.
- On init, cache the section start/end for the .text and .plt
sections in DwarfImageDebugInfo. Use them to make the check
for classifying addresses significantly cheaper.

* Created "types" subdirectory for basic types and moved Types.h,
SourceLocation, TargetAddressRange there.
* Added TargetAddressRangeList, representing a list of address ranges.
* Array: Added copy constructor and assignment operator.
* Added DwarfFunctionDebugInfo.
* ElfFile: Also read the program headers and provide access to the segment
information.
* DWARF:
- Some work on DIECompileUnitBase and DIESubprogram to handle attributes we
need.
- Added DwarfUtils class which provides static utility methods. Currently some
to get DIE names. Only provisionally implemented yet.
- Read range list attribute values from the .debug_ranges section. Extended
AttributeValue to handle them correctly (ref-counting).
* DwarfImageDebugInfo:
- Implemented GetFunctions() for real, i.e. we return functions for all
subprogram debug info entries we find (those that refer to actual
functions, that is).
- Implemented the fallback part of LoadSourceCode() (reading the code from the
file and disassembling it).
Things should hopefully work as before, just a bit slower and with less accurate
function names, if DWARF debug info is available. Promising, eh? ;-)

* Added TeamDebugInfo which serves as factory for ImageDebugInfos.
* Added the DWARF code to the build again. It's not used yet, though.
