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.
Hyperscan
Hyperscan is a high-performance multiple regex matching library. It follows the regular expression syntax of the commonly-used libpcre library, but is a standalone library with its own C API.
Hyperscan uses hybrid automata techniques to allow simultaneous matching of large numbers (up to tens of thousands) of regular expressions and for the matching of regular expressions across streams of data.
Hyperscan is typically used in a DPI library stack.
Documentation
Information on building the Hyperscan library and using its API is available in the Developer Reference Guide.

Versioning
The master branch on Github will always contain the most recent release of
Hyperscan. Each version released to master goes through QA and testing before
it is released; if you're a user, rather than a developer, this is the version
you should be using.
Further development towards the next release takes place on the develop
branch.
