Build error with libbullet

[olzhas]

Hello everyone,
today I updated dart to 5.0.0, then built it and tried to rebuild my project. I failed to do obtaining this error:

/usr/local/include/dart/collision/bullet/BulletTypes.h:50: error: 'btInfinityMask' was not declared in this scopec
return btInfinityMask;
^

The problem can be fixed removing the line BulletTypes.h:50.

I use libbullet 2.81 on ubuntu 14.04.2 x86_64.

The dummy function was added to suppress unused-variable-warnings due to btInfinityMask but it doesn't seem to be exposed on all the platforms. Actually bitInfinityMask is surrounded by some preprocessors, and Bullet 2.83 added similar code only when the variable is exposed.

I don't know how to expose the dummy function only when bitInfinityMask is exposed. Maybe we should remove the dummy function and let the compiler to complains warnings.

This should be fixed by #480. Please confirm.

Closing for now. Please reopen if it sill doesn't work.
