Allow multiple context managers in one with statement, as proposed
...
in http://codereview.appspot.com/53094 and accepted by Guido.
The construct is transformed into multiple With AST nodes so that
there should be no problems with the semantics.

Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} with
...
POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing
a POP_TOP on each conditional and sometimes allows the peephole optimizer to
skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.

Get rid of __context__, per the latest changes to PEP 343 and python-dev
...
discussion.
There are two places of documentation that still mention __context__:
Doc/lib/libstdtypes.tex -- I wasn't quite sure how to rewrite that without
spending a whole lot of time thinking about it; and whatsnew, which Andrew
usually likes to change himself.

Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.

Add support for absolute/relative imports and if/else expressions:
...
- regenerate ast.py
- add future flags for absolute-import and with-statement so they
(hopefully) properly get set in code-object flags
- try out if/else expressions in actual code for the hell of it.
Seems to generate the same kind of bytecode as the normal compiler.

PEP 343 -- the with-statement.
...
This was started by Mike Bland and completed by Guido
(with help from Neal).
This still needs a __future__ statement added;
Thomas is working on Michael's patch for that aspect.
There's a small amount of code cleanup and refactoring
in ast.c, compile.c and ceval.c (I fixed the lltrace
behavior when EXT_POP is used -- however I had to make
lltrace a static global).
