Fix bug where size of through association is not correct after adding a has_many association (occurs only before main object has been reloaded).

Refactoring: replace the mix of variables like @finder_sql, @counter_sql, etc with just a single scope hash (created on initialization of the proxy). This is now used consistently across all associations. Therefore, all you have to do to ensure finding/counting etc is done correctly is implement the scope correctly.

Revert "Revert "Generate proper :counter_sql from :finder_sql when there is a newline character immediately following 'SELECT' [#2118 state:resolved]""

This reverts commit 80f1f863.

The feature doesn't work on Postgres, so don't test it on Postgres.
Also, Postgres compatibility is irrelevant to the ticket/patch in question.

Revert "Generate proper :counter_sql from :finder_sql when there is a newline character immediately following 'SELECT' [#2118 state:resolved]"

This reverts commit 4851ca9e.

The tests do not pass for postgresql.

You can now add an :inverse_of option to has_one, has_many and belongs_to associations.  This is best described with an example:

class Man < ActiveRecord::Base
  has_one :face, :inverse_of => :man
end

class Face < ActiveRecord::Base
  belongs_to :man, :inverse_of => :face
end

m = Man.first
f = m.face

Without :inverse_of m and f.man would be different instances of the same object (f.man being pulled from the database again).  With these new :inverse_of options m and f.man are the same in memory instance.

Currently :inverse_of supports has_one and has_many (but not the :through variants) associations.  It also supplies inverse support for belongs_to associations where the inverse is a has_one and it's not a polymorphic.

AssociationCollection now starts transactions by calling
AssociationCollection#transaction instead of @owner.transaction or
@reflection.klass.transaction.

[#1081 state:committed]

Add special AssociationReflection methods for creating association objects, and modify the code base to use those methods instead of creating association objects directly. This allows plugins to hook into association object creation behavior.
