* lisp/ob-python.el (org-babel-python-evaluate-session): Fix a few
related issues with :session :results value blocks, including broken
if-else statements, indented blocks with blank lines, and returning
the wrong value when underscore has been used.
(org-babel-python--eval-ast): New constant variable, a string
consisting of Python code to execute a source block using ast.
Previously, python blocks with parameters ":session :results value"
were entered line-by-line into the Python session, which could cause
issues around indentation and new lines. Now, such python blocks are
written to temp files, then the built-in ast python module is used to
parse and execute them, and to extract the last line separately to
return as a result. Introduces a change in behavior, requiring that
the last line must be a top-level expression statement if its result
is to be saved (otherwise, the result is None).
* lisp/ob-python.el (org-bable-python-evaluate-session):
Syntax error occurs when evaluating the following code block:
\#+begin_src python :session
if True:
1
2
\#+end_src
A blank line is required for top level module code to end an indented block, such as a for loop, try/except, or if statement.

TINYCHANGE
* lisp/ob-python.el (orb-babel-python-evaluate-session): When :session
:results output, send multiline code blocks to tmpfile and execute in
Python with exec().
(org-babel-python--exec-tmpfile): New variable.
* testing/lisp/test-ob-python.el (test-ob-python/session-multiline):
Test for :session with multiple lines and indentation.

Use NAME instead of TBLNAME.
TBLNAME is deprecated syntax since Org 8.
I started from the 78ec8e commit then cherry-picked and squashed
commits that have been done in master since then, except the bad
commits that overwrote the tree (in master) with the tree in maint.
This commit also bumps the version number to 7.8.06.
The only "fix" that was made between 78ec8e and the previous commit
is e0072f which has been reported to break stuff.
This fixes a wrong merge that should not have happened:
commit 7e903a merges the master branch into the maint branch,
while we really want to keep the maint branch a bugfix-only
branch.
This commit reverts back the maint branch to its state before
merging the master branch. From there, we will fix remaining
problems with the maint branch (e.g. copyright issues) then
release this maint branch as Org-mode 7.8.05.
