Display values of multiple throttle.up and throttle.down in the first part of status bar

[chros73]

Display values of multiple throttle.up and throttle.down in the first part of status bar, also change name of config directive.

Currently the beginning of status bar looks like this:
[Throttle 500/1500 KB] [Rate: 441.6/981.3 KB]

Include the max limit of the throttles, the main upload rate and the upload rate of the throttles (in this order); and main download rate and the download rate of the selected throttles.

Possible cases look like these:

[Throttle 200 / 500 KB] [Rate 107.4 / 298.6 KB]
[Throttle 200(114) / 500 KB] [Rate 107.0(1.0|105.9) / 307.6 KB]
[Throttle 200 / 500(250) KB] [Rate 124.7 / 298.2(298.2|0.0) KB]
[Throttle 200(114) / 500(250) KB] [Rate 115.9(1.7|114.2) / 333.9(333.9|0.0) KB]

[Throttle 3500(75|25) / 8000 KB] [Rate 1745.5(1635.1|85.0|25.4) /   7.3 KB]

• make the displayable throttle names configurable via config file: ui.status.throttle.up.set and ui.status.throttle.down.set
• original code is refactored
• throttle.up and throttle.down values can be specified simultanously (as in the last example)
• name of throttles must be specified without surrounding quotes (the setting no longer a string but a list)
  • ui.status.throttle.up.set = slowup , tardyup
  • ui.status.throttle.down.set = slowup
• limitation is that every group (there are 4 possible groups) can contain the following number of characters (it leaves space for at least 5 throttles to be displayed):
  • limit: 40 chars
  • rate: 50 chars
• don't display this extra info of a given throttle in the following cases:
  • there isn't any throttle name as the config variables suggest or the given name is "NULL"
  • the throttle is not throttled (=0)
  • the global upload/download is not throttled (=0) (the throttle won't be taken into account in this case)

Refers to: #447 , #564 (comment)

I want to modify this one next, to be able to set/display multiple throttle groups.

[chros73]

I have modified the pull request (updated the description as well), major changes are:

• original code is refactored
• name of the config variables are changed to: ui.status.throttle.up.set and ui.status.throttle.down.set
• name of throttles must be specified without surrounding quotes (the setting is no longer a string but a list)
  • ui.status.throttle.up.set = slowup , tardyup
  • ui.status.throttle.down.set = slowup
• limitation is that every group (there are 4 possible groups) can contain the following number of characters (it leaves space for at least 5 throttles to be displayed):
  • limit: 40 chars
  • rate: 50 chars

Enjoy!

@rakshasa : Thanks for the new release!
I'll update my pending PRs on the current releases in the upcoming weeks, if I'll have time.

Only this one had problems, so I rebased it on current master and solved the merge conflicts.
All my other patches are fine, no need to rebase them.

@rakshasa, it would be really nice of you if you would merge these, so I wouldn't have to do this one more time :) Thanks!
And you can try these features/fixes out using the new release of rtorrent-ps-ch.
