      py: Allow builtins to be overridden. · 78d702c3
      Damien George authored
      This patch adds a configuration option (MICROPY_CAN_OVERRIDE_BUILTINS)
      which, when enabled, allows to override all names within the builtins
      module.  A builtins override dict is created the first time the user
      assigns to a name in the builtins model, and then that dict is searched
      first on subsequent lookups.  Note that this implementation doesn't
      allow deleting of names.
      
      This patch also does some refactoring of builtins code, creating the
      modbuiltins.c file.
      
      Addresses issue #959.

      modsys: Add sys.print_exception(exc, file=sys.stdout) function. · 46c3ab20
      Paul Sokolovsky authored
      The function is modeled after traceback.print_exception(), but unbloated,
      and put into existing module to save overhead on adding another module.
      Compliant traceback.print_exception() is intended to be implemented in
      micropython-lib in terms of sys.print_exception().
      
      This change required refactoring mp_obj_print_exception() to take pfenv_t
      interface arguments.
      
      Addresses #751.

      py: Add mp_pending_exception global variable, for VM soft interrupt. · 124df6f8
      Damien George authored
      This allows to implement KeyboardInterrupt on unix, and a much safer
      ctrl-C in stmhal port.  First ctrl-C is a soft one, with hope that VM
      will notice it; second ctrl-C is a hard one that kills anything (for
      both unix and stmhal).
      
      One needs to check for a pending exception in the VM only for jump
      opcodes.  Others can't produce an infinite loop (infinite recursion is
      caught by stack check).

      py: Store bytecode arg names in bytecode (were in own array). · 1084b0f9
      Damien George authored
      This saves a lot of RAM for 2 reasons:
      
      1. For functions that don't have default values, var args or var kw
      args (which is a large number of functions in the general case), the
      mp_obj_fun_bc_t type now fits in 1 GC block (previously needed 2 because
      of the extra pointer to point to the arg_names array).  So this saves 16
      bytes per function (32 bytes on 64-bit machines).
      
      2. Combining separate memory regions generally saves RAM because the
      unused bytes at the end of the GC block are saved for 1 of the blocks
      (since that block doesn't exist on its own anymore).  So generally this
      saves 8 bytes per function.
      
      Tested by importing lots of modules:
      
      - 64-bit Linux gave about an 8% RAM saving for 86k of used RAM.
      - pyboard gave about a 6% RAM saving for 31k of used RAM.

      py: Implement builtin reversed() function. · 4c03b3a8
      Damien George authored
      reversed function now implemented, and works for tuple, list, str, bytes
      and user objects with __len__ and __getitem__.
      
      Renamed mp_builtin_len to mp_obj_len to make it publically available (eg
      for reversed).
