Make rganalysis and rglimiter elements GAP-flag aware.

Original commit message from CVS:
* gst/replaygain/gstrganalysis.c (gst_rg_analysis_init),
(gst_rg_analysis_transform_ip):
* gst/replaygain/gstrglimiter.c (gst_rg_limiter_init),
(gst_rg_limiter_transform_ip):
Make rganalysis and rglimiter elements GAP-flag aware.
* tests/check/elements/rganalysis.c: (test_gap_buffers),
(rganalysis_suite):
* tests/check/elements/rglimiter.c (test_gap), (rglimiter_suite):
