result_of clash in interprocess tests

[Chris Jefferson]

Lots of interprocess tests have:

using namespace boost; using namespace std;

and then use result_of. This causes clashes for libraries (such as libc++) which are starting to add support for std::result_of.

I can see two obvious fixes:

1) Remove the 'using namespace std;'. They don't actually seem to be doing anything.

2) Qualify result_of with boost::

I assume (1) is the obvious fix. Except I wondered if the 'using namespace std' in most tests was there for some reason?

[Chris Jefferson]

Removes 'using namespace std' from conflicting tests. Adds 'std::' to count and endl in the one test which did not have them.

Updated patch

[Chris Jefferson]

Added a new patch, that fixes the existing issues, and one new one, by adding a boost::fusion:: to a couple of result_of calls, in a test.

[Ion Gaztañaga]

using namespace std was removed from interprocess but those patches are for boost::fusion so I guess we need to change the bug owner.

[Joel de Guzman]

patch applied. I'll commit as soon as all the tests pass. i'm closing this one.
