b7dd75c904 Handle nested items correctly in typestate_check 
Summary says it all. Actually, only nested objects and functions
are handled, but that's better than before. The fold that I was using
before to traverse a crate wasn't working correctly, because annotations
have to reflect the number of local variables of the nearest enclosing
function (in turn, because annotations are represented as bit vectors).
The fold was traversing the AST in the wrong order, first filling in
the annotations correctly, but then re-traversing them with the bit
vector length for any outer nested functions, and so on.

Remedying this required writing a lot of tedious boilerplate code
because I scrapped the idea of using a fold altogether.

I also made typestate_check handle unary, field, alt, and fail.

Also, some miscellaneous changes:
* added annotations to blocks in typeck
* fix pprust so it can handle spawn
* added more logging functions in util.common
* fixed _vec.or
* added maybe and from_maybe in option
* removed fold_block field from ast_fold, since it was never used

f6be25a870 Update foregoing patches to leave rust_crate alone. 
Apparently it can't live in the main binary, since on non-Linux
platforms, dynamics libs won't find symbols in the binary. This
removes the crate_map pointer from rust_crate again, and instead
passes it as an extra argument to rust_start. Rustboot doesn't pass
this argument, but supposedly that's okay as long as we don't actually
use it on that platform.

148e6f7b00 Make log the log level configurable per module 
This overloads the meaning of RUST_LOG to also allow
'module.submodule' or 'module.somethingelse=2' forms. The first turn
on all logging for a module (loglevel 3), the second sets its loglevel
to 2. Log levels are:

 0: Show only errors
 1: Errors and warnings
 2: Errors, warnings, and notes
 3: Everything, including debug logging

Right now, since we only have one 'log' operation, everything happens
at level 1 (warning), so the only meaningful thing that can be done
with the new RUST_LOG support is disable logging (=0) for some
modules.

TODOS:
 * Language support for logging at a specific level
 * Also add a log level field to tasks, query the current task as well
   as the current module before logging (log if one of them allows it)
 * Revise the C logging API to conform to this set-up (globals for
   per-module log level, query the task level before logging, stop
   using a global mask)

Implementation notes:

Crates now contain two extra data structures. A 'module map' that
contains names and pointers to the module-log-level globals for each
module in the crate that logs, and a 'crate map' that points at the
crate's module map, as well as at the crate maps of all external
crates it depends on. These are walked by the runtime (in
rust_crate.cpp) to set the currect log levels based on RUST_LOG.

These module log globals are allocated as-needed whenever a log
expression is encountered, and their location is hard-coded into the
logging code, which compares the current level to the log statement's
level, and skips over all logging code when it is lower.

63e87c102d typestate_check can now handle expr_block, expr_if, and expr_binary 
(caveat for the latter: it assumes that binary operations are strict;
a TODO is to detect or and and and correctly reflect that they're lazy
in the second argument). I had to add an ann field to ast.block,
resulting in the usual boilerplate changes.

Test cases that currently work (if you uncomment the typestate pass
in the driver) (all these are under test/compile-fail):

fru-typestate
ret-uninit
use-uninit
use-uninit-2
use-uninit-3

d7e8818414 Further work on typestate. Handles expr_rec and expr_assign now. 
Also changed the ts_ann field on statements to be an ann instead,
which explains most of the changes.

As well, got rid of the "warning: no type for expression" error
by filling in annotations for local decls in typeck (not sure whether
this was my fault or not).

Finally, in bitv, added a clone() function to copy a bit vector,
and fixed is_true, is_false, and to_str to not be nonsense.

I think just about every type can be used as a block result now. There's quite
a proliferation of tests here, but they all test slightly different things and
some are split out to remain XFAILed. The tests of generic vectors are still
XFAILed because generic aliased boxes still don't work in general.

2e90bd94de Continued sketching out code for checking states against preconditions. 
It's still sketchy. I added a typestate annotation field to statements
tagged stmt_decl or stmt_expr, because a stmt_decl statement has a typestate
that's different from that of its child node. This necessitated trivial
changes to a bunch of other files all over to the compiler. I also added a
few small standard library functions, some of which I didn't actually end
up using but which I thought might be useful anyway.

4fc8de1969 Last pieces of self-call support. 
The last few pieces of the hack that lets us use trans.trans_call() to
translate self-calls, plus a fix for the parser buy that was
preventing self-call expressions from getting past parsing.
test/run-pass/obj-self.rs works now (as in it actually prints "hi!"
twice!).

b8bb2e118e Further on the path toward self-awareness. 
Mostly:

  * Merciless refactoring of trans.rs so that trans_call can work for
    self-calls as well as other kinds of calls

Also:

  * Various changes to go with having idents, rather than exprs, in
    expr_call_self AST nodes
  * Added missing case for SELF token to token.to_str()

Tim Chevalier
3130348ee1 Started adding support for typestate checking. 
I added a new field to the ast "ann" type for typestate information.
Currently, the field contains a record of a precondition bit vector and
postcondition vector, but I tried to structure things so as to make
it easy to change the representation of the typestate annotation type.
I also had to add annotations to some syntactic forms that didn't have
them before (fail, ret, be...), with all the boilerplate changes
that that would imply.

The main call to the typestate_check entry point is commented out and
the actual pre-postcondition algorithm only has a few cases
implemented, though the overall AST traversal is there. The rest of
the typestate algorithm isn't implemented yet.
