Add header support to multipart Upload Part - Copy

- Trivial change to all headers to be passed in to the

- Header support is required to set headers such as:
  * x-amz-copy-source-if-match
  * x-amz-copy-source-if-none-match
  * x-amz-copy-source-if-unmodified-since
  * x-amz-copy-source-if-modified-since

Merge branch 'master' of git://github.com/boto/boto
Integration and enhancement of slick53 #478 #272

Starting with a base from slick53: add support for LBR and
WRR records; add documentation; e-factor to pass record
objects opaquely and reduce code duplication; rename tests
file to test_layer2.py and add testing of LBR and WRR
records.
Add status attr to DescribeSpotInstanceRequests

This required a bump of the ec2 API version.
Update boto/auth.py

When using a proxy server AWSAuthConnection.build_base_http_request will modify the http_request.path to include the host header.  It caches the original path in the auth_path field so that the signature can be later correctly generated. 

Both the HMACAuthV3HTTPHandler and HMACAuthV4HTTPHandler signature generation methods in auth.py look at the original path and not auth_path which means boto will generate an incorrect signature when using a proxy server.

This patch updates those signature generation methods to use auth_path instead of path.
Update EC2 unit tests to use new API version.
Add support for bid status messages for spot instances.
