Support http stat code detection engine, fast pattern(mpm engine included). Fix http stat code setup function. Fix pcre option for stat msg keyword. With this the pcre options for server_body is Q, for stat_msg is Y and for stat_code is S 13 years ago			`#define DETECT_PCRE_RELATIVE 0x00001`
			`#define DETECT_PCRE_RAWBYTES 0x00002`
pcre: parsing cleanup Remove all flags indicating the buffer type. They were only used at parse time. Because of this the DetectPcreData_ structure could shrink to 32 bytes. 11 years ago			`#define DETECT_PCRE_CASELESS 0x00004`

pcre P modifier support (pcre match over http body requests) 15 years ago
Rename all structure definitions in the "typedef struct _SomeStruct" format to "typedef struct SomeStruct_" to make the Doxygen output more useful. Remove the Trie multi pattern matcher code. It wasn't used anymore. 16 years ago			`typedef struct DetectPcreData_ {`
