* Fix a bug where configuration error ends up doing a huge allocation, rather than catching the error. Add some documentation to the slabmgr code.
* Add a unit test and some documentation to answer the question in issue #107. I can't see how offset and map_start would end up being different.
* Rewrite of SGX file_map to remove TOCTTTOU now passes all unit tests
* Apply a similar fix to file_read.
* Factor complicated verification code into a common helper routine.
* Adjust the memory copying strategy so that all bits in the returned buffed are exactly the same bits as verified in the trusted, scratch buffer.
* Fixing the TOCTOU issue in file checking
* Adding comments for load_trusted_file() and copy_and_check_trusted_file(); Deprecate the old design
* Documenting the file checking mechanism
Plenty of bugfixes for Linux kernel later than 3.5 and Ubuntu later than 10.10.
More organized code to improve portability.
Regression tests for Pal to test completeness of implementation.
