Provides helpers for migrating from Duktape 1.x to 2.x:

• Add duk_v1_compat.c to list of C sources to compile.

• Ensure duk_v1_compat.h is in the include path.

• Include the extra header in calling code:

  #include "duktape.h"
  #include "duk_v1_compat.h"
  
  /* ... */
  
  duk_dump_context_stdout(ctx);  /* Removed in Duktape 2.x. */
  

The helpers don't restore full 1.x compatibility because some API calls such as duk_safe_call() have changed in an incompatible manner.

The old APIs are documented in:
