Implement EncodedBuffer that strip pii based on given privacy request.
The reason to implement another buffer is the length-delimited field's
size could change when its submessage gets stripped. It also intends to
keep the orignal data around for other requests to consume it.
In addition, the section implementation has adapted EncodedBuffer so
write out to each request's fd could be request-specific. The next step
is allow requests to set its privacy spec.
Notice the current design set the privacy spec of dropbox to AUTOMATIC,
this behavior might change in the future.

0) Implements a skeleton of incident_helper
1) Implements FileSection class which calls incident_helper to parse
file content to protobuf
2) Adds Kernel Wake Sources to incident.proto and makes it parsed by
FileSection
3) Adds basic gtests to test FdBuffer, io_utils, FileSection
implementation
