It allows a backend to do requests to user by calling a registered
callback function.

In the requests manager, it locks each call to prevent multiple backends
requesting the same think at a time, from an idea of Adrien Clerc.

Closes #945

Current gpgv has a bug where the gpgv command does not work

A patch has already been sent upstream :
https://lists.gnupg.org/pipermail/gnupg-devel/2015-December/030623.html

Using gpg --verify rather than gpgv fixes the issue.
If gpg is not found, gpgv is used as a fallback.

flake8 --select E713, semi-manual fixing

flake8 --select W391,E302,E301,E304

autopep8 can't fix W391 even though it claims it can.
Fixed using a simple custom script.

This is a cleaner approach that requires less configuration
in other applications.
This also easily allows us to have another color.

Many checks were made on being exactly at the DEBUG level, they were
fixed to also check on being below DEBUG (i.e. DEBUG_FILTERS).

weboob.tools.browser -> weboob.deprecated.browser
weboob.tools.parsers -> weboob.deprecated.browser.parsers
weboob.tools.mech -> weboob.deprecated.mech
weboob.browser2 -> weboob.browser
weboob.core.exceptions -> weboob.exceptions

Also, the new tree for browser2 is:

weboob.browser: import weboob.browser.browsers.* and weboob.browser.url.*
weboob.browser.browsers: all browsers (including PagesBrowser and LoginBrowser)
weboob.browser.url: the URL class
weboob.browser.profiles: all Profile classes
weboob.browser.sessions: WeboobSession and FuturesSession
weboob.browser.cookies: that's a cookies thing
weboob.browser.pages: all Page and derivated classes, and Form class
weboob.browser.exceptions: specific browser exceptions
weboob.browser.elements: AbstractElement classes, and 'method' decorator
weboob.browser.filters.*: all filters

They bring nothing of value (we never use import * anyway) and introduce
a maintenance burden.

The __all__ that I left might not be very useful either but at least
they are not a pain to maintain; they are also used by pyflakes in some
cases.
