Activate our new multibyte implementation.

Browse Source 
* add implementations for the following multibyte-related
  functions:
    btwoc()
    mblen()
    mbrlen()
    mbrtowc()
    mbsinit()
    mbtowc()
    wcrtomb()
    wcswidth()
    wctob()
    wctomb()
* the implementation of the above function live in a symbol
  named __<name>, the above symbol names are defined as a weak
  alias to the internal ones - TODO: we need to make sure to
  only invoked the internal functions (i.e. prepended with __)
  in order to avoid problems with symbol preemption.
* deactivate the limited mb implementation we provided before,
  as well as respective stuff from glibc
