Improve signatures to pre/post_* decorators #276

Copied from #153 (comment):

There are a few improvements to the pre/post_* and validates* decorators I'd like to make before the 2.0.0 final release.


  • As pointed out in #216, there is no way to get access to the target object (the data to be (de)serialized). This is possible, however, with validates_schema via the pass_original param.
  • Also related to #216: The "raw" param is misleading. Users might think that it means that the raw target object is passed, but it does not.


  • Rename raw -> pass_many.
  • Add pass_original to post_dump and post_load. Maybe rename to pass_target or pass_input--not sure about this.

Update: pass_original only makes sense for post_dump and post_load.

Add pass_original param to post_load and post_dump
ref #276

IMPORTANT: This effectively drops support for pre/post_*
staticmethods and classmethods because the pass_original relies
on the setting of the __marshmallow_kwargs__ attribute set on
the methods, which doesn't seem to be working static and class
methods. We may revisit this in the future, but for the time
being, processors must be instance methods.
