dict: const pointers to dictionary where possible
...
This avoids temporaries or ugly casting in the calling code where
const dictionaries are used. Esp. helpful when writing C++ wrappers
for an AVDictionary having const member functions and CTORs with const
references.

Not guaranteed to be in nanosecond resolution. On iOS 7 the duration
of one tick is 125/3 ns which is still more than an order of magnitude
better then microseconds.
Replace decicycles with the neutral UNITS. Decicycles is strange but
tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time
is just silly.
