The msg handling of trace-cmd for the listen and record code is
overly complex due to the multiplexing functions. Rewrite the code
such that it is easier to understand. This will allow us to extend
it in the future for the virt-server work.

Head SHA1: 9420ffed51b5a1a28c175efc41fdd49507acda89
Steven Rostedt (Red Hat) (34):
trace-cmd: Remove the creating of msg out of tracecmd_msg_send()
trace-cmd: Move tracecmd_msg_send_and_wait_for_msg() into its only user
trace-cmd: Turn tracecmd_msg data into an anonymous union
trace-cmd: Remove unused structure tracecmd_msg_error
trace-cmd: Move size and cmd in tracecmd_msg into its own header struct
trace-cmd: Move the tracecmd_msg pointers into their own union
trace-cmd: Just use the buf field for sending pointers
trace-cmd: Use an array to map msg types and min sizes
trace-cmd: Merge msg_do_write_check() into msg_write()
trace-cmd: Simplify msg_free() by using min sizes
trace-cmd: Add tracecmd_msg_init() helper function
trace-cmd: Remove mulitplexer tracecmd_msg_create()
trace-cmd: Simplify msg_read_extra()
trace-cmd: Have msg_free() zero out msg contents
trace-cmd: Verify RINIT was received after TINIT msg sent
trace-cmd: Make send_metadata a flag in the output handle
trace-cmd: Pass cpu count and port array to make_rinit()
trace-cmd: Pass cpu_count instead of having it as a global
trace-cmd: Pass in client_ports instead of using a global variable
trace-cmd msg: Add debug prints of messages sent and received
trace-cmd msg: Move the saved closing fd to the caller
trace-cmd listen: Add better output on error of connections
trace-cmd msg: Create a msg_handle to pass around for saved state
trace-cmd msg: Add server structure of msg_handler
trace-cmd: Remove global use_tcp variable
trace-cmd: Move protocol version into msg_handler
tracecmd: Clean up handling of cpu_count
tracecmd listen: Have pagesize passed as return not parameter
trace-cmd: Have cpu_count reside in instances and not be global
trace-cmd: Add option CPUCOUNT to buffer instance options
trace-cmd: Have msg_handle part of the buffer instance
trace-cmd record: Allow instances to be recorded over the network
trace-cmd: Have keep and profile be flags of buffer instance
trace-cmd: Add network handle into buffer instance
Steven Rostedt (VMware) (4):
trace-cmd recorder: Check if pipe_size was modified by fcntl(F_GETPIPE_SZ)
pevent: Simplify pointer print logic and fix %pF
pevent: Handle new pointer processing of bprint strings
trace-cmd record: Fix clearing out the ctx->instance when used in for_all_instances()
