Added an out-of-bounds check when fetching a PE TLS data address

Also made the unix-style addresses more generic for the other tests

- Moves TLSArchInfo into Archinfo proper
- Moves relocations into a submodule of backends, to reflect their usage
- Minor style changes everywhere

Support for parsing the TLS directory of a PE file

Fix contains_addr for ELFs and refactor a little



See merge request !74

Fix spelling of "independent"



See merge request !73

Lots of messed up stuff. moved tls into backends so deps work correctly, generally prodded at tls until it worked

Fixed address checks in the base Backend class

Allow symbols to be resolved from the main binary (with priority) for all objects. Makes the wyvern example work again.

Add paramter to clemory reads to not respect updates. Use this in calculating relocation addends. Closes #163 on github

Fixed missing sections_map in PE backend

Only segments were being checked for addresses, which was causing checks to fail for PE files because PE files use sections rather than segments. If a segment search fails then we search through sections

Do not attempt demangling symbols if no symbols exist



See merge request !72

Be gentle with file descriptors



See merge request !71

Introduce transparent stream patching to prevent file copying and also support recovery from malicious section pointers
