5a1b02bc10 Fix uninitialized use of scatter_unit_uX due to padding 
These non-packed structures are placed into a std::vector.  Later, they
contents of the vector are memcpy'd and the CRC of this space is taken.
Some compilers will zero the struct padding but GCC8.2 with -O2 at least
will not.  This means that the CRC is based on uninitialized memory.

Since it is expected that these bytes will be memcpy'd, zero in place once
they're in the std::vector.

Found by Valgrind.

Q.v. Issue #148

08bf909e2b ng_violet: make calcSplitRatio operation faster 
Implements count_reachable in a less malloc-happy way, improving
compile performance. Adds a count() function to small_color_map.

50ea83cb26 Move cpuid checks inline. 
During fat runtime function resolution there was a chance that the PLT
might not be initialised in time for us to call the cpuid check
functions. Moving them inline means there is no PLT to worry about.

Fixes #78

14cf5c3684 small_vector: require boost >= 1.61 
We use the small_vector constructors introduced in Boost 1.61 (trac bug
11866, github commit b436c91). If the Boost version is too old, we fall
back to using std::vector.

4528485a56 determinise: use find first, rather than emplace 
For non-trivial StateSet types, copying to do the emplace if it is
already in the map is more expensive than checking with find() first.

9cf66b6ac9 util: switch from Boost to std::unordered set/map 
This commit replaces the ue2::unordered_{set,map} types with their STL
versions, with some new hashing utilities in util/hash.h. The new types
ue2_unordered_set<T> and ue2_unordered_map<Key, T> default to using the
ue2_hasher.

The header util/ue2_containers.h has been removed, and the flat_set/map
containers moved to util/flat_containers.h.

31141dd35b determinise: use queue, improve api 
- Use a queue rather than always building the full vector of state
   sets.
 - Make more use of move, emplace, reserve.
 - Write directly into dstates argument.
 - Return bool rather than int.

345897f096 cpuid: exclude AVX512 flag when target not enabled 
If we have a fat runtime build without AVX512 enabled, we should not
pick up the AVX512 flag from cpuid.

09f5699df7 flat_set/map: workaround for gcc-4.8 C++11 defect 
The STL shipped with gcc-4.8 does not provide
vector::erase(const_iterator) for C++11, instead only taking a mutable
iterator.  This causes problems with flat_set/map if we don't have
Boost small_vector available and we fall back to std::vector.

We work around this by providing a function to construct a mutable
iterator given a const_iterator for internal use.
