Implement SMB app-layer parser for SMB1/2/3. Features:
- file extraction
- eve logging
- existing dce keyword support
- smb_share/smb_named_pipe keyword support (stickybuffers)
- auth meta data extraction (ntlmssp, kerberos5)
READ replies with large data chunks are processed partially to avoid
queuing too much data. When the final chunk was received however, the
start of the chunk would already tag the transaction as 'done'. The
more aggressive tx freeing that was recently merged would cause this
tx to be freed before the rest of the in-progress chunk was done.
This patch delays the tagging of the tx until the final data has been
received.
In normal records it will try to continue parsing.
GAP 'data' will be passed to file api as '0's. New call is used
so that the file API does know it is dealing with a GAP. Such
files are flagged as truncated at the end of the file and no
checksums are calculated.
Initial version of a filetracker API that depends on the filecontainer
and wraps around the Suricata File API in C.
The API expects chunk based transfers where chunks can be out of order.
