23e5f06594 add new Literal API for pure literal expressions: 
Design compile time api hs_compile_lit() and hs_compile_lit_multi()
to handle pure literal pattern sets. Corresponding option --literal-on
is added for hyperscan testing suites. Extended parameters and part of
flags are not supported for this api.

e15954a4bd Avoid array-bounds error when debug/fortify enabled 
This code causes GCC to error out due to a bounds error with the following set

	-D_GLIBCXX_DEBUG
	-D_FORTIFY_SOURCE=2

The solution is to copy via iterator.

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.

ExpressionInfo.
