Reorganize org-edit-src-code; allow buffer-local `org-edit-src-content-indentation'

* lisp/org-src.el (org-edit-src-code): When generating the code edit
buffer, it is necessary for several variables to inherit their values
from the parent org buffer. These changes collect all such variables
together into a single association list of (variable-name value)
pairs. In addition, a new variable is added to the list:
`org-edit-src-content-indentation'. This has the effect that a buffer
local value can be used for that variable.
