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.

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.

221229f71c gcc7: comments for falling through a switch case 
GCC 7 adds a warning -Wimplicit-fallthrough to catch when falling
through a switch statement without a break. Since we actually want that
behaviour sometimes, we can add a comment so the compiler knows we
intended the fallthrough.

bbd64f98ae allow streams to marked as exhausted in more cases 
At stream boundaries, we can mark streams as exhausted if there are no
groups active and there are no other ways to report matches. This allows us
to stop maintaining the history buffer on subsequent stream writes.
Previously, streams were only marked as exhausted if a pure highlander case
reported all patterns or the outfix in a sole outfix case died.

68bf473e2e 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.
