Damien George 71c5181a8d Convert Python types to proper Python type hierarchy.
Now much more inline with how CPython does types.

Damien George eb7bfcb286 Split qstr into pools, and put initial pool in ROM.
Qstr's are now split into a linked-list of qstr pools.  This has 2
benefits: the first pool can be in ROM (huge benefit, since we no longer
use RAM for the core qstrs), and subsequent pools use m_new for the next
pool instead of m_renew (thus avoiding a huge single table for all the
qstrs).

Still would be better to use a hash table, but this scheme takes us part
of the way (eventually convert the pools to hash tables).

Also fixed bug with import.

Also improved the way the module code is referenced (not magic number 1
anymore).

Damien George fe8fb9165c py: remove depedence on strcat and stpcpy.
This fixes Issue #29, and means the core is no longer dependent on
string functions, except strlen.

Damien 732407f1bf Change memory allocation API to require size for free and realloc. 2013-12-29 19:33:23 +00:00
Damien d99b05282d Change object representation from 1 big union to individual structs.
A big change.  Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object).  This scheme follows CPython.  Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.

Also change name prefix, from py_ to mp_ (mp for Micro Python).
