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.

5a1b02bc10 Fix uninitialized use of scatter_unit_uX due to padding 
These non-packed structures are placed into a std::vector.  Later, they
contents of the vector are memcpy'd and the CRC of this space is taken.
Some compilers will zero the struct padding but GCC8.2 with -O2 at least
will not.  This means that the CRC is based on uninitialized memory.

Since it is expected that these bytes will be memcpy'd, zero in place once
they're in the std::vector.

Found by Valgrind.
