Title: "BOOST_SYSTEM_NOEXCEPT does not name a type" fix

Compilation fails when boost version is 1.49:
```
lazy_bdecode.cpp:558:30: error: expected ‘;’ at end of member declaration
lazy_bdecode.cpp:558:36: error: ‘BOOST_SYSTEM_NOEXCEPT’ does not name a type
lazy_bdecode.cpp:559:39: error: expected ‘;’ at end of member declaration
lazy_bdecode.cpp:559:45: error: ‘BOOST_SYSTEM_NOEXCEPT’ does not name a type
lazy_bdecode.cpp:560:74: error: expected ‘;’ at end of member declaration
lazy_bdecode.cpp:560:80: error: ‘BOOST_SYSTEM_NOEXCEPT’ does not name a type
lazy_bdecode.cpp:564:51: error: expected initializer before ‘BOOST_SYSTEM_NOEXCEPT’
lazy_bdecode.cpp:569:60: error: expected initializer before ‘BOOST_SYSTEM_NOEXCEPT’
lazy_bdecode.cpp:592:2: error: expected ‘}’ at end of input`
```
Added
```
#ifndef BOOST_SYSTEM_NOEXCEPT
#define BOOST_SYSTEM_NOEXCEPT BOOST_NOEXCEPT
#endif
```
for compatability.
