| | |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some contexts, *cough*like at facebook*cough*, dynamic linking is used in contexts which aren't truly dynamic. That is, the guarantee is maintained that a program will only ever execute against the library version it was compiled to interact with. For those situations, introduce a compile-time flag that overrides hiding these unstable APIs in shared objects.

Reason is : `nbSearches` provides a built-in protection for these cases. The problem with patterns is that they dramatically increase the number of candidates to visit. But with a low nbSearches, the match finder just aborts early. In such cases, pattern analysis adds some complexity without reducing total nb of candidates. It actually increases compression ratio a little bit, by filtering only "good" candidates, but at a measurable speed cost, so it's not a good trade-off. This patch makes pattern analysis optional. It's enabled for levels 8+ only.

| | |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lz4opt is only competitive vs lz4hc level 10. Below that level, it doesn't match the speed / compression effectiveness of regular hc parser. This patch propose to extend lz4opt to levels 10-12. The new level 10 tend to compress a bit better and a bit faster than previous one (mileage vary depending on file) The only downside is that `limitedDestSize` mode is now limited to max level 9 (vs 10), since it's only compatible with regular HC parser. (Note : I suspect it's possible to convert lz4opt to support it too, but haven't spent time into it).
