[PATCH v13 0/4] Add support for Lua scripting

[Victor Krapivensky]

Changelog:
 * Factored out the preparational part from the "initial support for Lua
   scripting" commit.
 * func_next_sc is no longer exposed as strace.C.next_sc; instead, it is
   passed as a part of private data table, and is now wrapped by
   strace.next_sc, which saves the current trace control pointer to a
   local variable.
 * Helper library function now don't take tcp arguments; instead, this
   local variable is used.
 * New function strace.inject_retval that wraps strace.C.inject_retval.
 * Added validations for personality numbers and various stuff that gets
   converted to cdata const char *. It is much more difficult to
   unintentionally crash strace process from a script now.
 * Other minor fixes.
