0bf86a7c15 scratch: remove quick validity check 
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.

9b4ba34c68 Fix segfaults on allocation failure (#4) 
Throw std::bad_alloc instead of returning nullptr from
ue2::AlignedAllocator. Allocators for STL containers are expected never
to return with an invalid pointer, and instead must throw on failure.
Violating this expectation can lead to invalid pointer dereferences.

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.
