This removes need for some casts (at least, more than it adds need
for new casts!).
py: Don't automatically intern strings in parser.2014-05-25T21:06:06+00:00Damien Georgedamien.p.george@gmail.com2014-05-25T21:06:06+00:00urn:sha1:5042bce8fb268849ba1afcbeb946b840318c4e49
This completes non-automatic interning of strings in the parser, so that
doc strings don't take up RAM. It complicates the parser and compiler,
and bloats stmhal by about 300 bytes. It's complicated because now
there are 2 kinds of parse-nodes that can be strings: interned leaves
and non-interned structs.

Parser shouldn't raise exceptions, so needs to check when memory
allocation fails. This patch does that for the initial set up of the
parser state.
Also, we now put the parser object on the stack. It's small enough to
go there instead of on the heap.
This partially addresses issue #558.

Doesn't help with RAM reduction because doc strings are interned as soon
as they are encountered, which is too soon to do any optimisations on
them.
py: Turn down amount of RAM parser and compiler use.2014-05-05T12:19:03+00:00Damien Georgedamien.p.george@gmail.com2014-05-05T12:19:03+00:00urn:sha1:66e18f04d811197854c0ce970b2dc8ac17deaebc
There are 2 locations in parser, and 1 in compiler, where memory
allocation is not precise. In the parser it's the rule stack and result
stack, in the compiler it's the array for the identifiers in the current
scope. All other mallocs are exact (ie they don't allocate more than is
needed).
This patch adds tuning options (MP_ALLOC_*) to mpconfig.h for these 3
inexact allocations.
The inexact allocations in the parser should actually be close to
logarithmic: you need an exponentially larger script (absent pathological
cases) to use up more room on the rule and result stacks. As such, the
default allocation policy for these is now to start with a modest sized
stack, but grow only in small increments.
For the identifier arrays in the compiler, these now start out quite
small (4 entries, since most functions don't have that many ids), and
grow incrementally by 6 (since if you have more ids than 4, you probably
have quite a few more, but it wouldn't be exponentially more).
Partially addresses issue #560.
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/.
