check for rlimits on Linux

[daschuer]

Gives a hint in sound preferences if the Limits are not set.

Please use the absolute path:
#include "util/rlimit.h"

Other than the minor comments, LGTM

Imo we can leave out translator comments here, because dealing with small HTML blobs like links or %1 variables are explained in the glossary as well as the translator pages, see http://mixxx.org/wiki/doku.php/internationalization . OTOH I would suggest to delete the <ul> tags ,also for the other bullet points in the latency tips. If we`d move them to separate rows in a horizontal layout, each line is presented as separate string in the translation interface.

I am in favor not to change the lines above, because they are already translated. If we try to make them more easy to translate by changing them we will in fact force the translators to translate them again.

If the check is performed on Linux only, isn't it redundant to display the hint in sound preferences on Mac ( and probably Windows)?

[daschuer]

This should be only displayed in the Linux version. I will prepare a fix.
