Reason for revert: Broke chromium fyi build. Original issue's description: > Convert internal representation of Srtp cryptos from string to int. > > Note that the coversion from int to string happens in 3 places > 1) SDP layer from int to external names. mediasession.cc GetSupportedSuiteNames. > 2) for SSL_CTX_set_tlsext_use_srtp(), converting from int to internal names. > 3) stats collection also needs external names. > > External names are like AES_CM_128_HMAC_SHA1_80, specified in sslstreamadapter.cc. > Internal names are like SRTP_AES128_CM_SHA1_80, specified in opensslstreamadapter.cc. > > The conversion from string to int happens in one place only, SDP layer, SrtpFilter::ApplyParams(). > > BUG=webrtc:5043 > > Committed: https://crrev.com/2764e1027a08a5543e04b854a27a520801faf6eb > Cr-Commit-Position: refs/heads/master@{#10701} TBR=juberti@webrtc.org,pthatcher@webrtc.org,juberti@google.com NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=webrtc:5043 Review URL: https://codereview.webrtc.org/1455233005 Cr-Commit-Position: refs/heads/master@{#10702}
