Allows suppression of .pb-c.{c,h} file generation on a .proto file
basis.
protobuf-c.proto: Use the new option in itself, because the options are
never used by protobuf-c runtime, only by the protoc-gen-c compiler.
t/test-full.proto: import protobuf-c.proto to test that
protobuf-c.pb-c.h dependency does not get included in test-full.pb-c.h.
The protobuf common.h header currently has a "using std::string;"
statement that pulls std::string into the google::protobuf namespace:
ce66f6047d/src/google/protobuf/stubs/common.h (L195)
I plan to delete that line soon. To keep protobuf-c working, this commit
updates the generator to fully qualify std::string.
Upstream protobuf removed scoped_ptr.h, which provided the scoped_ptr
that we depended on, in commit 67952fab2c766ac5eacc15bb78e5af4039a3d398
(67952fab2c).
This commit converts uses of scoped_ptr type to idiomatic C++11
std::unique_ptr, similar to the changes in the protobuf commit.
This has been tested on protobuf 3.0.0 (the version currently in Debian)
as well as the latest protobuf 3.6.1 release.
per https://code.google.com/p/protobuf/source/detail?r=50, the license
on google-originated protobuf code was switched from Apache-2.0 to
BSD-3-Clause (so-called "New BSD" license). update any of the google
license statements to use this new license.
per email with dave, drop the third clause on his BSD-3-Clause license,
so this now becomes BSD-2-Clause.
make sure to use consistent indentation and wrapping throughout.
