76e1571749 Upstream: consistent error handling after u->input_filter_init().
In all cases ngx_http_upstream_finalize_request() with NGX_ERROR now used.
Previously used NGX_HTTP_INTERNAL_SERVER_ERROR in the subrequest in memory
case don't cause any harm, but inconsistent with other uses.

84d2ecf87e Gzip: clearing of c->buffered if all data are flushed.
This allows to finalize unfinished responses while still sending as
much data as available.

be6fbbb47e Event pipe: fixed writing cache header to a temp file.
With previous code the p->temp_file->offset wasn't adjusted if a temp
file was written by the code in ngx_event_pipe_write_to_downstream()
after an EOF, resulting in cache not being used with empty scgi and uwsgi
responses with Content-Length set to 0.

Fix it to call ngx_event_pipe_write_chain_to_temp_file() there instead
of calling ngx_write_chain_to_temp_file() directly.

f52042498d Fixed ngx_http_test_reading() to finalize request properly.
Previous code called ngx_http_finalize_request() with rc = 0.  This is
ok if a response status was already set, but resulted in "000" being
logged if it wasn't.  In particular this happened with limit_req
if a connection was prematurely closed during limit_req delay.

1936a67647 Sub filter: fixed matching after a partial match.
After a failed partial match we now check if there is another partial
match in previously matched substring to fix cases like "aab" in "aaab".

The ctx->saved string is now always sent if it's present on return
from the ngx_http_sub_parse() function (and reset accordingly).  This
allows to release parts of previously matched data.

ce7a5a0537 Sub filter: fixed incomplete last buffer on partial match.
If a pattern was partially matched at a response end, partially matched
string wasn't send.  E.g., a response "fo" was truncated to an empty response
if partially mathed by a pattern "foo".

32e167e211 SPDY: fixed segfault with "client_body_in_file_only" enabled.
It is possible to send FLAG_FIN in additional empty data frame, even if it is
known from the content-length header that request body is empty.  And Firefox
actually behaves like this (see ticket #357).

To simplify code we sacrificed our microoptimization that did not work right
due to missing check in the ngx_http_spdy_state_data() function for rb->buf
set to NULL.

809d05769b Xslt: exsltRegisterAll() moved to preconfiguration.
The exsltRegisterAll() needs to be called before XSLT stylesheets
are compiled, else stylesheet compilation hooks will not work.  This
change fixes EXSLT Functions extension.

615d558843 Events: honor NGX_USE_GREEDY_EVENT when kqueue support is enabled.
Currently this flag is needed for epoll and rtsig, and though these methods
usually present on different platforms than kqueue, nginx can be compiled to
support all of them.

4ef36b38a1 Configure: perl Makefile rebuild after configure.
The $NGX_AUTO_CONFIG_H added to perl module Makefile dependencies to
make sure it's always rebuild after a configure.  It is needed as we
expand various variables used for Makefile generation during configure
(in particular, nginx version).

d79c8abcaa Core: fixed possible use of an uninitialized variable.
The call to ngx_sock_ntop() in ngx_connection_local_sockaddr() might be
performed with the uninitialized "len" variable.  The fix is to initialize
variable to the size of corresponding socket address type.

The issue was introduced in commit 05ba5bce31e0.

af18946d76 Core: extended ngx_sock_ntop() with socklen parameter.
On Linux, sockaddr length is required to process unix socket addresses properly
due to unnamed sockets (which don't have sun_path set at all) and abstract
namespace sockets.

88fc0f793e Fixed ngx_http_parse_chunked() minimal length calculation.
Minimal data length we expect for further calls was calculated incorrectly
if parsing stopped right after parsing chunk size.  This might in theory
affect clients and/or backends using LF instead of CRLF.

982f4de9f0 Fixed build on Linux with x32 ABI.
On Linux x32 inclusion of sys/sysctl.h produces an error.  As sysctl() is
only used by rtsig event method code, which is legacy and not compiled
in by default on modern linuxes, the sys/sysctl.h file now only included
if rtsig support is enabled.

Based on patch by Serguei I. Ivantsov.

11ff177a9f Core: support several "error_log" directives.
When several "error_log" directives are specified in the same configuration
block, logs are written to all files with a matching log level.

All logs are stored in the singly-linked list that is sorted by log level in
the descending order.

Specific debug levels (NGX_LOG_DEBUG_HTTP,EVENT, etc.) are not supported
if several "error_log" directives are specified.  In this case all logs
will use debug level that has largest absolute value.

40c4e7b73c Valgrind: supressed complaints about uninitialized bytes.
Valgrind complains if we pass uninitialized memory to a syscall:

==36492== Syscall param sendmsg(msg.msg_iov[0]) points to uninitialised byte(s)
==36492==    at 0x6B5E6A: sendmsg (in /usr/lib/system/libsystem_kernel.dylib)
==36492==    by 0x10004288E: ngx_signal_worker_processes (ngx_process_cycle.c:527)
==36492==    by 0x1000417A7: ngx_master_process_cycle (ngx_process_cycle.c:203)
==36492==    by 0x100001F10: main (nginx.c:410)
==36492==  Address 0x7fff5fbff71c is on thread 1's stack

Even initialization of all members of the structure passed isn't enough, as
there is padding which still remains uninitialized and results in Valgrind
complaint.  Note there is no real problem here as data from uninitialized
memory isn't used.

start due to sigaction() failure.  If compiled with NGX_VALGRIND defined,

work with stderr, as already used by ngx_init_cycle() and main() since
rev. d8316f307b6a.
