cap le acl buffer size, added hci function

git-svn-id: http://btstack.googlecode.com/svn/trunk@2870 1a0a8af8-31b5-11de-8e0c-53a27eea117e
use hci_acl_le_data_buffer_length to get max le l2cap mtu

git-svn-id: http://btstack.googlecode.com/svn/trunk@2871 1a0a8af8-31b5-11de-8e0c-53a27eea117e
used HCI_ACL_PAYLOAD_SIZE as att request buffer size

git-svn-id: http://btstack.googlecode.com/svn/trunk@2872 1a0a8af8-31b5-11de-8e0c-53a27eea117e
use HCI_ACL_PAYLOAD_SIZE to determine L2CAP MTU

git-svn-id: http://btstack.googlecode.com/svn/trunk@2873 1a0a8af8-31b5-11de-8e0c-53a27eea117e
att mtu is per default ATT MTU MIN. During MTU exchange is set to a max l2cap le mtu
