Victor Julien 84448d3bae tests: remove unnecessary flow locks 
Added once to satisfy debug validation, but we don't mix unittests
and debug validation anymore.

Jason Ish fcbdc30426 dns: create transaction even if z-bit was set 
It appears that DNS servers will still process a DNS request even if the
z-bit is set, our parser will fail the transaction. So create the
transaction, but still set the event.

Ticket #4924

Philippe Antoine 7d0a39412b detect: use u32 for InspectionBufferMultipleForList 
So that we do not have an endless loop casting index to
u16 and having more than 65536 buffers in one transaction

Changes for all protocols, even ones where it is impossible
to have such a pattern, so as to avoid bad pattern copy/paste
in the future

Victor Julien 3dc50322db detect: fix multi inspect buffer issue; clean up 
Fix multi inspect buffer API causing cleanup logic in the single
inspect buffer paths. This could lead to a buffer overrun in the
"to clear" logic.

Multi buffers now use InspectionBufferSetupMulti instead of
InspectionBuffer. This is enforced by a check in debug validation.

Simplify the multi inspect buffer setup code and update the callers.

Victor Julien 13cebb1857 detect: fix heap overflow issue with buffer setup 
In some cases, the InspectionBufferGet function would be followed by
a failure to set the buffer up, for example due to a HTTP body limit
not yet being reached. Yet each call to InspectionBufferGet would lead
to the matching list_id to be added to the
DetectEngineThreadCtx::inspect.to_clear_queue. This array is sized to
add each list only once, but in this case the same id could be added
multiple times, potentially overflowing the array.

Victor Julien 4dff903b35 detect: introduce pkt mpm engines 
Instead of the hardcode L4 matching in MPM that was recently introduced,
add an API similar to the AppLayer MPM and inspect engines.

Share part of the registration code with the AppLayer.

Implement for the tcp.hdr and udp.hdr keywords.

Victor Julien 3eec088d31 detect/parse: error out on unused sticky buffers 7 years ago
Victor Julien 0b3220a0df detect: improve inspect buffer handling 
Fix and Optimize cleanup. For the simple single inspect buffer optimize
the cleanup by keeping track of the actually used buffers. This avoid
looping over unused buffers.

Fix the case of cleaning not being done after a tx if the next tx is
also inspected in the context of the same packet.

Fix cleanup of the multi-inspect buffers. Optimize in 2 ways. First
like with single keep track of which multi-inspect buffers have been
used. Second, keep a max of the buffers within a multi-inspect buffer.
Use this max to limit (nested) looping.

Victor Julien ab1200fbd7 compiler: more strict compiler warnings 
Set flags by default:

    -Wmissing-prototypes

    -Wbad-function-cast

Sascha Steinbiss e6044aaf1c mpm/spm: check for SSSE3 and enable/disable HS 
The new Hyperscan 4.4 API provides a function to check for SSSE3
presence at runtime. This allows us to fall back to non-Hyperscan
matchers on systems without SSSE3 even when the suricata executable
is built with Hyperscan support. Addresses Redmine issue #2010.

int foo(void)

Rather than:
