more xpra top features

[Antoine Martin]

show more details:

• bandwidth used?
• fps?
• client rendering mode?
• video regions?
• encodings used? (as a percentage? of updates / pixels?)

Updates:

• r24784 cpuinfo and client hostname
• r24787 move connection info to a separate line and add more details: encoder, compressor

Updates:

• r24850: show speaker, microphone and av-sync
• r24852: show window gravity as a human readable string
• r24859: minor output adjustments
• r24855 + r24860: show client opengl caps
• r24861 + r24862: warn if server data is out of date
• r24863: show server side opengl caps
• r24864 + r24866: bug fixes
• r24868: use a session id to more easily distinguish client info data and exclude our own
• r24869: fix flickering
• r24871: fix terminal messed up on connection failure
• r24982: list sessions
• r24984: navigate the list of sessions and launch subcommands

This will do for now. Will follow up in #2553.

• bandwidth used: we would need to collect this with a timer, server side
• "fps", "video regions" and "encodings": those are both per window and per-user: so difficult to show, as this would take a lot of space
• client rendering mode: we now have opengl info
