libsecp256k1's API changed, so update key.cpp to use it. Libsecp256k1 now has explicit context objects, which makes it completely thread-safe. In turn, keep an explicit context object in key.cpp, which is explicitly initialized destroyed. This is not really pretty now, but it's more efficient than the static initialized object in key.cpp (which made for example bitcoin-tx slow, as for most of its calls, libsecp256k1 wasn't actually needed). This also brings in the new blinding support in libsecp256k1. By passing in a random seed, temporary variables during the elliptic curve computations are altered, in such a way that if an attacker does not know the blind, observing the internal operations leaks less information about the keys used. This was implemented by Greg Maxwell. |

Notes
The sources in this directory are unit test cases. Boost includes a unit testing framework, and since bitcoin already uses boost, it makes sense to simply use this framework rather than require developers to configure some other framework (we want as few impediments to creating unit tests as possible).
The build system is setup to compile an executable called "test_bitcoin" that runs all of the unit tests. The main source file is called test_bitcoin.cpp, which simply includes other files that contain the actual unit tests (outside of a couple required preprocessor directives). The pattern is to create one test file for each class or source file for which you want to create unit tests. The file naming convention is "<source_filename>_tests.cpp" and such files should wrap their tests in a test suite called "<source_filename>_tests". For an examples of this pattern, examine uint160_tests.cpp and uint256_tests.cpp.
For further reading, I found the following website to be helpful in explaining how the boost unit test framework works: http://www.alittlemadness.com/2009/03/31/c-unit-testing-with-boosttest/.
