Use CTRL-E to enter paste mode. Prompt starts with "===" and accepts
all characters verbatim, echoing them back. Only control characters are
CTRL-C which cancels the input and returns to normal REPL, and CTRL-D
which ends the input and executes it. The input is executed as though
it were a file. The input is not added to the prompt history.
With this patch parse nodes are allocated sequentially in chunks. This
reduces fragmentation of the heap and prevents waste at the end of
individually allocated parse nodes.
Saves roughly 20% of RAM during parse stage.
This fixes errors like these ones:
modffi.c: In function 'return_ffi_value':
modffi.c:143:29: error: cast to pointer from integer of different size
[-Werror=int-to-pointer-cast]
const char *s = (const char *)val;

These errors can be highlighted when building micropython from MIPS64
n32 because ffi_arg is 64-bit wide and the pointers on MIPS64 n32 are
32-bit wide, so it's trying to case an integer to a pointer (or
vice-versa) of a different size. We should cast first the pointer (or the
integer) to a pointer sized integer (intptr_t) to fix that problem.

Linking against local libffi (and other libs in future) is triggered by
"make MICROPY_STANDALONE=1". Before that, dependent libs should be built
with "make deplibs".
Indeed, this flag efectively selects architecture target, and must
consistently apply to all compiles and links, including 3rd-party
libraries, unlike CFLAGS, which have MicroPython-specific setting.
