Set flags by default:

-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.
In preparation of turning input to keyword parsers to const add
options to the common rule parser to enforce and strip double
quotes and parse negation support.
At registration, the keyword can register 3 extra flags:
SIGMATCH_QUOTES_MANDATORY: value to keyword must be quoted
SIGMATCH_QUOTES_OPTIONAL: value to keyword may be quoted
SIGMATCH_HANDLE_NEGATION: leading ! is parsed
In all cases leading spaces are removed. If the 'quote' flags are
set, the quotes are removed from the input as well.
The output of the list-keyword is modified to include the url to
the keyword documentation when this is available. All documented
keywords should have their link set.
list-keyword can be used with an optional value:
no option or short: display list of keywords
csv: display a csv output on info an all keywords
all: display a human readable output of keywords info
$KWD: display the info about one keyword.
When handling error case on SCMallog, SCCalloc or SCStrdup
we are in an unlikely case. This patch adds the unlikely()
expression to indicate this to gcc.
This patch has been obtained via coccinelle. The transformation
is the following:
@istested@
identifier x;
statement S1;
identifier func =~ "(SCMalloc|SCStrdup|SCCalloc)";
@@
x = func(...)
... when != x
- if (x == NULL) S1
+ if (unlikely(x == NULL)) S1
