lib-http: message parsers: Record beginning of parsed data.

Updated copyright notices to include the year 2018.

lib-http: Restructured the header, message, request, and response parsers to have an extensible and consistent API using flags. Extended the test suites with a few cases that test parsing with and without the STRICT flag.

lib-http: message parser: Don't allocate a pool for the next message until it is needed. This prevents wasting memory when no message is being parsed.

Updated copyright notices to include the year 2017.

global: Replaced all instances of memset(p, 0, sizeof(*p)) with the new i_zero() macro. Used the following script: C_FILES=`git ls-files *.c` H_FILES=`git ls-files *.h` for F in "$C_FILES $H_FILES"; do echo "$F" perl -p -i -e 's/safe_memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero_safe(&$1)/g' $F perl -p -i -e 's/safe_memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero_safe($1)/g' $F perl -p -i -e 's/memset\(&\(?([^,]*)\)?,\s*0,\s*sizeof\(\g1\)\)/i_zero(&$1)/g' $F perl -p -i -e 's/memset\(([^,]*),\s*0,\s*sizeof\(\*\g1\)\)/i_zero($1)/g' $F done

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

global: Replaced all i_stream_read_data() with _more() and _bytes()

lib-http: Always set *_obj=NULL first in deinit functions (mainly for consistency) This doesn't usually matter, but in case deinit calls some callback they may be trying to access the partially destroyed object.

lib-http: request parser: Added support for explicitly finishing payload of previous request.

lib-http: request parser: Made sure that partially parsed requests never have stale string values. Due to the fact that we assign method and target fields early for proper error messages, stale fields from previous requests could have ended up in a partially parsed new request.

lib-http: Forgot to assign pointer parameter to NULL in request/response parser deinit functions.

lib-http: Updated comments to RFC7230/RFC7231.

Added "fall through" comments to switch statements where break is intentionally missing. This should make Coverity quiet about these..

Updated copyright notices to include year 2014.

lib-http: Added option to the header parser to make it lenient towards illegal characters in header field content. The offending characters are then skipped without error. This is required for the http client as a workaround for bugs in certain HTTP servers. This behavior is explicitly not enabled for the http-request-parser as used by our own HTTP server implementation.

lib-http: Fixed handling of limits=NULL parameter for http_request_parser_init. Got messed up in patch queue.

lib-http: Added support for parsing Expect: header (currently only accepts `100-continue').

lib-http: http-request-parser: Added function to test whether payload from previous request is still being parsed. This is needed in the server implementation to check whether a request is completely read.

lib-http: Implemented limits on request method and target length.

lib-http: Added support for enforcing a payload limit for incoming HTTP messages.

lib-http: Adjusted message and request parsers to return an error code.

lib-http: Adjusted request parser to pre-parse the request target and host header into a proper target url.

lib-http: Improved display of invalid characters in parse error messages.

lib-http: Implemented limits on overall HTTP header size, size of individual header fields and the number of fields in the header.

lib-http: Unified http-request.h and http-response.h headers. Renamed struct http_response_header to struct http_header_field, encapsulated the array in struct http_header and put it all in http-header.h/c Added inline utility functions for header querying and getting response/request payload size.

lib-http: Improved message header and body parsing for better RFC compliance. Added pre-parsed transfer-encoding and connection header content (array) to parsed message struct. Fixed message body handling for when both transfer-encoding and content-length headers are missing. Now duplicates of unique important message headers yield an error.

lib-http: Adjusted message parser to accept pool from caller.

lib-http: Adjusted response and request parsers to accept a request/response object to fill with data, rather than have it return one.

lib-http: Fixed handling of non-standard CRLF at end of request.

lib-http: Implemented http-request-parser for HTTP servers. Moved code common with it and http-response-parser to http-message-parser.
