MinidumpFileWriter writes the top-level object to a minidump file. This consists of a MINIDUMP_HEADER and a list of MINIDUMP_DIRECTORY entries that point to streams, which are second-level objects in minidump files. This change also adds the base class for stream writers, MinidumpStreamWriter. TEST=minidump_test MinidumpFileWriter* R=rsesek@chromium.org Review URL: https://codereview.chromium.org/432863006
