To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.
This patch adds that feature in all places. This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.
py: Move to guarded includes, everywhere in py/ core.2015-01-01T20:32:09+00:00Damien Georgedamien.p.george@gmail.com2015-01-01T20:27:54+00:00urn:sha1:51dfcb4bb7613ed164952712d9a5235a7b833cde
Addresses issue #1022.
py: Optimise lexer by exposing lexer type.2014-12-05T19:35:18+00:00Damien Georgedamien.p.george@gmail.com2014-12-05T19:35:18+00:00urn:sha1:a4c52c5a3d19b5527023fedfaae96cb717d03802
mp_lexer_t type is exposed, mp_token_t type is removed, and simple lexer
functions (like checking current token kind) are now inlined.
This saves 784 bytes ROM on 32-bit unix, 348 bytes on stmhal, and 460
bytes on bare-arm. It also saves a tiny bit of RAM since mp_lexer_t
is a bit smaller. Also will run a bit more efficiently.

It defines types used by all other headers.
Fixes #691.
Add license header to (almost) all files.2014-05-03T22:27:38+00:00Damien Georgedamien.p.george@gmail.com2014-05-03T22:27:38+00:00urn:sha1:04b9147e150d2d6fa3750f312fe328b6a71c1b28
Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Previously, a failed malloc/realloc would throw an exception, which was
not caught. I think it's better to keep the parser free from NLR
(exception throwing), hence this patch.
Implement proper exception type hierarchy.2014-02-15T16:10:44+00:00Damien Georgedamien.p.george@gmail.com2014-02-15T16:10:44+00:00urn:sha1:c5966128c7c8a768f6726f299d85d5daef6bed48
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of. When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).
Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.
Handling of parse error changed to match new exceptions.
mp_const_type renamed to mp_type_type for consistency.
