Template antioch_version for basic_ostream usage

Reworks antioch_version_stdout to delegate to antioch_version.  New
antioch_version accepts any templated basic_ostream you like, avoids
repeatedly flushing the stream via std::endl, and returns the stream for
later use.

Result is, caveat build time, identical on my system.

Desirable as dumping version information to a ostringstream can be handy
at times.

Update m4 file to not check for library linkage

We went header only, so the antioch.m4 check should not be checking
for a library to link against anymore.
Make utility function inline

When compiling in GRINS, the compiler complained about multiple
definitions of of this function. Making it inline fixed it for me.
Not sure why there weren't any complaints within Antioch proper.
