Wrap all loggers used by job, extractor, downloader, and postprocessor
objects into a (custom) LoggerAdapter that provides access to the
underlying job, extractor, pathfmt, and kwdict objects and their
properties.
__init__() signatures for all downloader and postprocessor classes have
been changed to take the current Job object as their first argument,
instead of the current extractor or pathfmt.

otherwise the next call to download() with a fallback URL could see
the partially downloaded "remains" from the previous, failed download
attempt and "continue" it, writing the second half of a potentially
different version of that file.
… except ENOSPC (No space left on device), since there is no reason to
continue downloading in that case.
All other errors that would prevent downloading data and writing it to
disk get already raised during directory creation and are therefore not
checked here.
- change 'has_extension' from a simple flag/bool to a field that
contains the original filename extension
- rename 'keywords' to 'kwdict' and some other stuff as well
- inline 'adjust_path()'
- put enumeration index before filename extension (#306)
The default value for both is 'false', i.e. duplicate URLs are NOT
ignored.
The previous behavior was to always ignore duplicate URLs to make
'--abort-on-skip' work properly when new images where added to the
beginning of a collection while gallery-dl is running.
Instead of replacing 'https' with 'http' for every URL in
'get_downloader()', this now only happens once during downloader
initialization. Also unit tests.
Simplified universal serialization support in json.dump() can be achieved
by passing 'default=str', which was already the case in DataJob.run()
for -j/--dump-json, but not for the 'metadata' post-processor.
This commit introduces util.dump_json() that (more or less) unifies the
JSON output procedure of both --write-metadata and --dump-json.

This allows for stuff like "{extractor.url}" and "{extractor.category}"
in logging format strings.
Accessing 'extractor' and 'job' in any way will return "None" if those
fields aren't defined, i.e. in general logging messages.
Child extractors are now directly constructed with Extractor.from_url()
if the extractor class is known beforehand, instead of using
extractor.find() and searching through all possible extractor classes.
