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.

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.

86c5f7feb1 FDR: Squash buckets of included literals in FDR confirm 
- Change the compile of literal matchers to two passes.
 - Reverse the bucket assignment in FDR, bucket with longer literals has
   smaller bucket id.
 - Squash the buckets of included literals and jump to the the program of
   included literals directly from parent literal program without going
   through FDR confirm for included iterals.

to look for accel states at init.
