Remove unnecessary package definitions in ASD files.
With ASDF 3 our redefinition of PERFORM when called with a COMPILE-OP and
PROTOBUF-SOURCE-FILE is unnecessary, so use a reader conditional to remove it.
Instead, when running with ASDF 3, define INPUT-FILES on a COMPILE-OP and
PROTOBUF-SOURCE-FILE to be the output files of the PROTO-TO-LISP operation.
Use std::unique_ptr instead of scoped_ptr and scoped_array.
Use the nibbles library when encoding integers.
Be more careful about overflow when parsing backwards.
Increment version number.
Merge branch 'master' into unique-ptr
Use -stdc=c++0x argument so that GCC understands unique_ptr.
Increment version number.
Remove ASDF 2 compatibility code.  Increment version.
Merge remote-tracking branch 'upstream/master'
