math::parseFloat is locale-dependent

Environment

• OS Version: Ubuntu 18.04 LTS
• Source or binary build? ign-math6 9519ce7

parseFloat relies on std::stod which is locale-dependent.

When using my locale LC_NUMERIC=es_AR.UTF-8; the Collada importer in ign-common/graphics/src/ColladaLoader.cc will end up reading garbage. Hence this little sensor:

will end up looking like this:

This bug is related to gazebosim/gz-common#120 and gazebosim/gz-rendering#365

Description

• Expected behavior: Collada loads the importer correctly
• Actual behavior: Collada loads a triangle soup

Steps to reproduce

1. Launch LC_ALL=es_AR.UTF-8 ign gazebo near_clip.sdf using near_clip.sdf

Workaround

Launching gazebo with LC_ALL=C fixes the issue.

I'm centralizing the information and issues related to locale independent conversions in gazebosim/gz-common#233. PRs are very welcome :)
