This patch defines new getsockopt options BT_SNDMTU/BT_RCVMTU for SCO socket to be compatible with other bluetooth sockets. These new options return the same value as option SCO_OPTIONS which is already present on existing kernels.

Changes in v3: - Fixed the commit message.
Changes in v2: - Used BT_SNDMTU/BT_RCVMTU instead of creating a new opt name. - Used the existing conn->mtu instead of creating a new member in struct sco_pinfo. - Noted that the old SCO_OPTIONS in sco_sock_getsockopt_old() would just work as it uses sco_pi(sk)->conn->mtu.
