Philippe Antoine b113bdd9e3 src: remove unused headers-exported functions 
+ remove double definition of IPPairLock

Ticket: #4083

Jason Ish 44388f1b69 src: make include guards more library friendly 
Include guards for libraries should use a prefix that is meaningful for
the library to avoid conflicts with other user code. For Suricata, use
SURICATA.

Additionally, remove the pattern of leading and trailing underscores as
these are reserved for the language implementation per the C and C++
standards.

Victor Julien 007a461d69 detect/parse: track negation during address parsing 
Fix address negation detection not resolving variables when
looking for the negation.

This patch makes use of the actual parsing routines to relay this
information to the signature parser.

Bug #3389.

Alexander Gozman 2cf2387e31 rules: optimize bidir rules with same src/dst 
As an optimization, reset bidirectional flag for rules with same src and dst.
If one created bidirectional rule like 'alert tcp any any <> any any ...',
the rule was checked twice (for each packet in every direction). This is
suboptimal and may give duplicated alerts. To avoid this, bidirectional
rules are now checked for the same src and dst (addresses and ports) and
if it's the case, the rule is treated as unidirectional and a corresponding
message is logged.

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

    -Wmissing-prototypes
    -Wmissing-declarations
    -Wstrict-prototypes
    -Wwrite-strings
    -Wcast-align
    -Wbad-function-cast
    -Wformat-security
    -Wno-format-nonliteral
    -Wmissing-format-attribute
    -funsigned-char

Fix minor compiler warnings for these new flags on gcc and clang.

Victor Julien e072e70ea6 alert: fix rate_filter issues 
Fix rate_filter issues: if action was modified it wouldn't be logged
in EVE. To address this pass the PacketAlert structure to the threshold
code so it can flag the PacketAlert as modified. Use this in logging.

Update API to use const where possible. Fix a timout issue that this
uncovered.

Victor Julien 215d0d54c7 detect: optimize rule address parsing 
Many rules have the same address vars, so instead of parsing them
each time use a hash to store the string and the parsed result.

Rules now reference the stored result in the hash table.
