sample: Use bernoulli_distribution from boost::, not stl:: or boost::TR1
The TR1 sub namespace no longer exists in recent versions of boost.
Previously, this was fixed by using the C++11 STL version if it's
available, otherwise falling back on TR1. But that didn't work
due to a slight incompatibility between the C++11 and the boost
version. The boost version still exists, just not under TR1--and
we already use it elsewhere in the codebase, so this should be
the cleanest fix.
Also fix memory-corruption crash in std::domain_error(), by copying formatted
string to memory allocated safely via postgres with palloc()
Also improve some non-critical C++ issues:
- Convert ptr_fun() to function() to get rid of C++11 deprecation warning
- src/dbal/Reference_proto.hpp: Fix an error in the template definition
of class Ref. The default value for IsMutable should be the value true
or false, not the type bool. The only reason this wasn't generating
compiler errors is that IsMutable happens to be passed explicitly in
every place in the code where the template is instantiated--so the
default was ignored.
- Hide global boost symbols from external libraries
We were already doing this for all STL symbols--for the same reasons,
doing it for boost as well should make MADlib more robust when
integrating with 3rd party libraries.
