Summary: cpp_regex_traits<charT>::toi() method fails in the MT case

Initial Comment:
cpp_regex_traits<charT>::toi() method fails to parse
the string correctly when it is used in multi-threaded
environment. Originally, I run into this problem in
regex parser code and traced it down to
cpp_regex_traits<charT>::toi() method (btw, this
happens on Linux only, Windows code goes thru a
different code path). 

I believe that the problem is caused by the fact that
*buffered* m_pimpl->m_sbuf and m_pimpl->m_is are used
inside cpp_regex_traits<charT>::toi() method without
locking. Thus, if two threads are trying to use it in
the same time, it fails.
