037bca67fd Allocate the dictionaries in examples/zran.c. 
This reduces the memory needed for dictionaries, and avoids the
need to reallocate the index at the end to return unused memory.

6378d33478 Provide a reusable inflate engine in the index in example/zran.c. 
Avoids the overhead of creating a new inflate engine for each
random access extraction.

be4db0a79a Set returned index to NULL on an index build error in zran.c. 
An attempt to use the returned pointer in deflate_index_extract()
will now return cleanly with an error. The returned pointer can
now also be used with deflate_index_free() even on error.

7e6dc429af Add a NOPRIME #define to zran.c to not use inflatePrime(). 
This supports zlib versions earlier than 1.2.3 (July 2005), as
well as incomplete clones of zlib that do not have inflatePrime().

d00c147f53 Clarify that prefix codes are counted in enough.c. 
There is no assurance that all prefix codes are reachable as
optimal Huffman codes for the numbers of symbols encountered in
a deflate block. This code considers all possible prefix codes,
which might be a larger set than all possible Huffman codes,
depending on the constraints.

17068938ce Avoid shift equal to bits in type (caused endless loop). 
Also clean up comparisons between different types, and some odd
indentation problems that showed up somehow.

A new endless loop was introduced by the clang compiler, which
apparently does odd things when the right operand of << is equal to
or greater than the number of bits in the type.  The C standard in
fact states that the behavior of << is undefined in that case.  The
loop was rewritten to use single-bit shifts.
