This extends the API surface so that custom certificates can be provided by an API user in both the standalone and factory creation paths for the OpenSSLAdapter. Prior to this change the SSL roots were hardcoded in a header file and directly included into openssladapter.cc. This forces the 100 kilobytes of certificates to always be compiled into the library. This is undesirable in certain linking cases where these certificates can be shared from another binary that already has an equivalent set of trusted roots hard coded into the binary. Support for removing the hard coded SSL roots has also been added through a new build flag. By default the hard coded SSL roots will be included and will be used if no other trusted root certificates are provided. The main goal of this CL is to reduce total binary size requirements of WebRTC by about 100kb in certain applications where adding these certificates is redundant.
