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.

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.

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.

fdr: move long literal handling into Rose

Move the hash table used for long literal support in streaming mode from
FDR to Rose, and introduce new instructions CHECK_LONG_LIT and
CHECK_LONG_LIT_NOCASE for doing literal confirm for long literals.
This simplifies FDR confirm, and guarantees that HWLM matchers will only
be used for literals < 256 bytes long.
