655549df7c [downloader:ytdl] add several options
The "default" downloader options (rate, retries, timeout, verify) are
mapped to corresponding youtube-dl options.

downloader.ytdl.logging tells the downloader to pass youtube-dl's output
to a Logger object.

downloader.ytdl.raw-options allows to pass arbitrary options to the
YoutubeDL constructor.

4a348990f4 adjust value resolution for retries/timeout/verify options
This change introduces 'extractor.*.retries/timeout/verify' options
as a general way to set these values for all HTTP requests.

'downloader.http.retries/timeout/verify' is a way to override these
options for file downloads only and will fall back to 'extractor.*.…*
values if they haven't been explicitly set.

Also: downloader classes now take an extractor object as first argument
instead of a requests.session.

188876d814 implement youtube-dl downloader module
URLs starting with 'ytdl:' will now be handled by youtube-dl.
There is probably a lot to fix and improve, but the basic use case
works.

TODO:
- format selection and ytdl options in general
- better filename/path handling
- ytdl support for "unsupported URLs"
- ...

ebe9b0a04c another attempt at downloader retry behavior
This commit changes the general behavior from
'Retry on every exception and abort on DownloadError' to
'Only retry on DownloadRetry exceptions and abort on every other one'

The previous version would have retried on several states which
would have no chance of ever succeeding (invalid URLs, etc.)

8f518e03f8 add options to set maximum download rate
- -r/--limit-rate as cmdline option
- downloader.http.rate as config option

This implementation very roughly uses the idea of the token bucket
algorithm [1] and mostly uses Wget's approach [2] as inspiration.

42e948584d fix downloader error handling

9a41002b77 fix partial downloads for 'text:' URLs
Using a filesize in bytes as offset into a Python string is not
a good idea if said file contains non-ASCII characters.

963670d73b add options to control usage of .part files (#29)
- '--no-part' command line option to disable them
- 'downloader.http.part' and 'downloader.text.part' config options

Disabling .part files restores the behaviour of the old downloader
implementation.

58e95a7487 share extractor and downloader sessions
There was never any "good" reason for the strict separation
between extractors and downloaders. This change allows for
reduced resource usage (probably unnoticeable) and less lines
of code at the "cost" of tighter coupling.
