* Fix string literal concatenation to not be interpreted as UD
literals.
* Add constexpr compatibility for non-integral static members.
* Use __typeof__ instead of typeof (should become decltype once this
actually becomes C++11).
* Add an appropriate cast for atomic_uintptr_t, since moving to C++11
means moving from <stdatomic.h> to <atomic>, which has better
typechecking (hooray for not macros!).

Approximate speed improvement is 10-15% for filter computation,
which is floating point intensive. This will be important
for devices without hw floating point support.

Improve dynamic audio resampler filter generation speed by 2x.
The resulting filters should be the same (excepting roundoff).
Also added check for upsampling sample rate changes to share
previously generated filters.
Modify the profiling to improve output format and sampling result
reliability.

This does not affect the existing resamplers.
New resampler accessed through additional quality settings:
DYN_LOW_QUALITY = 5
DYN_MED_QUALITY = 6
DYN_HIGH_QUALITY = 7
