replace /* fall through */ comment with __attribute_fallthrough__ macro
Note: not adding attribute to code with external origins:
xxhash.h (algo_xxhash.h)
ls-hpack/lshpack.c
so to avoid warnings, may need to compile with -Wno-implicit-fallthrough
(thx flynn)
To reduce log noise, skip warning trace reporting error on backend
socket if the connection has been upgraded, e.g. to websockets

When server.stream-request-body = 0 (the default), the entire request
body is collected before engaging the backend. For backends which
require data framing, this could lead to growth in memory use as large
requests were framed all at once.
Prefer to retain large request bodies in temporary files on disk and
frame in portions as write queue to backend drains below a threshold.

move code from connections-glue.c back into connections.c
move code from connections-glue.c to http-header-glue.c
rename connection_response_reset()
to http_response_reset()
rename connection_handle_read_post_error()
to http_response_reqbody_read_error()
r->con->reqbody_read() replaces connection_handle_read_post_state()
future: might provide different callbacks for request body with
Content-Length versus request body sent via Transfer-Encoding: chunked
(expansion of buffer_string_lenth() inline function and CONST_BUF_LEN()
macro, which always check for NULL, appears to cause the analyzer to
believe that a pointer might be NULL in cases where it otherwise can
not be NULL)
x-ref:
http://clang-analyzer.llvm.org/faq.html
stream request body using HTTP/1.1 Transfer-Encoding: chunked
(Note: if backend proxy target does not support HTTP/1.1,
then do not use server.stream-request-body = 1 or 2)
If not streaming to backend, collect request body
(now supporting Transfer-Encoding: chunked from client
and then sending with Content-Length to backend)

NB: r->tmp_buf == srv->tmp_buf (pointer is copied for quicker access)
NB: request read and write chunkqueues currently point to connection
chunkqueues; per-request and per-connection chunkqueues are
not distinct from one another
con->read_queue == r->read_queue
con->write_queue == r->write_queue
NB: in the future, a separate connection config may be needed for
connection-level module hooks. Similarly, might need to have
per-request chunkqueues separate from per-connection chunkqueues.
Should probably also have a request_reset() which is distinct from
connection_reset().
use global rather than passing around (server *) just for that
li_itostrn() and li_utostrn() return string length
(rather than requiring subsequent strlen() to find length)
convert all log_error_write() to log_error() and pass (log_error_st *)
use con->errh in preference to srv->errh (even though currently same)
avoid passing (server *) when previously used only for logging (errh)
