Damien George 5cbeacebdb py: Make math special functions configurable and disabled by default.
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.

They are however enabled in stmhal and unix, since we have the room.

Paul Sokolovsky 1f91e92cc6 py: Revamp mp_obj_print() to use Python streams.
Most of printing infrastructure now uses streams, but mp_obj_print() used
libc's printf(), which led to weird buffering issues in output. So, switch
mp_obj_print() to streams too, even though it may make sense to move it to
a separate file, as it is purely a debugging function now.

Paul Sokolovsky 9e6c82960e builtinimport: Revamp&refactor handling of relative imports.
Relative imports are based of a package, so we're currently at a module
within a package, we should get to package first.

Also, factor out path travsering operation, but this broke testing for
boundary errors with relative imports. TODO: reintroduce them, together
with proper tests.

Paul Sokolovsky e8432b3c72 stackctrl: Encode "recursion depth exceeded" message as qstr.
So corresponding exception can be thrown even under tight memory conditions.

Paul Sokolovsky fa3b895145 objexcept: Optimize traceback allocation for exception.
Traceback allocation for exception will now never lead to recursive
MemoryError exception - if there's no memory for traceback, it simply
won't be created.

Paul Sokolovsky 29c4f92e13 objexcept: Optimize using messages without formatting substitutions.
They are directly cast to str object, skipping allocation of formatting
buffer.

Paul Sokolovsky 3077fbff26 nlr: Add even more optional debugging logging.
Has to be enabled by manual editing, but at least it's there, as debugging
NLR issues may be weird.

Paul Sokolovsky e89cc13e5c nlr: If DEBUG, guard against recursive nlr_push().
Pushing same NLR record twice would lead to "infinite loop" in nlr_jump
(but more realistically, it will crash as soon as NLR record on stack is
overwritten).

as the rest of state.

Damien George 7d414a1b52 py: Parse big-int/float/imag constants directly in parser.
Previous to this patch, a big-int, float or imag constant was interned
(made into a qstr) and then parsed at runtime to create an object each
time it was needed.  This is wasteful in RAM and not efficient.  Now,
these constants are parsed straight away in the parser and turned into
objects.  This allows constants with large numbers of digits (so
addresses issue #1103) and takes us a step closer to #722.

Damien George 0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
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.

Damien George e1e359ff59 py: Put mp_sys_path, mp_sys_argv and gc_collected in mp_state_ctx_t.
Without mp_sys_path and mp_sys_argv in the root pointer section of the

Damien George 0d3cb6726d py: Change vstr so that it doesn't null terminate buffer by default.
This cleans up vstr so that it's a pure "variable buffer", and the user
can decide whether they need to add a terminating null byte.  In most
places where vstr is used, the vstr did not need to be null terminated
and so this patch saves code size, a tiny bit of RAM, and makes vstr
usage more efficient.  When null termination is needed it must be
done explicitly using vstr_null_terminate.
