Roll back fix for github issue #350 About Scratch Usage: For compile time, scratch space is strongly recommended to be allocated immediately after database generation. For runtime, besides using scratch for corresponding database, Hyperscan also allows user to use larger scratch space allocated for another database. When multiple concurrent threads need to use the same databases and a new scratch space is required, cloning the largest one is always safe. This is realized based on API hs_scratch_size() and hs_clone_scratch(). Behaviors beyond above are discouraged and results are undefined.
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.
