Clean changes introduced by 47abdbd

* Replace the save/load_buffer_state by a dynarray approach:
  - Filename and libname are added to a dynarray when first encountered
  - Load repeatedly the files in the dynarray until no new undefined
    symbol are encountered
* Replace snprintf by sprintf in libname_to_filename
* Use tcc_fileextension in filename_to_libname
* Introduce a tcc_strcpy_part fonction to copy only a subset of a
  string
* Move new_undef_syms declaration from tcc.h to tccelf.c
