Gzip static: "always" parameter in "gzip_static" directive.
With "always" gzip static returns gzipped content in all cases, without
checking if client supports it. It is useful if there are no uncompressed
files on disk anyway.
This directive allows to test desired flag as returned by memcached and
sets Content-Encoding to gzip if one found.
This is reimplementation of patch by Tomash Brechko as available on
http://openhack.ru/. It should be a bit more correct though (at least
I think so). In particular, it doesn't try to detect if we are able to
gunzip data, but instead just sets correct Content-Encoding.

Limit req: fix of rbtree node insertion on hash collisions.
The rbtree used in ngx_http_limit_req_module has two level of keys, the top is
hash, and the next is the value string itself. However, when inserting a new
node, only hash has been set, while the value string has been left empty.

Fixed the "include" directive.
The "include" directive should be able to include multiple files if
given a filename mask. Fixed this to work for "include" directives
inside the "map" or "types" blocks. The "include" directive inside
the "geo" block is still not fixed.

Radix tree preallocation fix.
The preallocation size was calculated incorrectly and was always 8 due to
sizeof(ngx_radix_tree_t) accidentally used instead of sizeof(ngx_radix_node_t).

Map: fixed optimization of variables as values.
Previous code incorrectly used ctx->var_values as an array of pointers to
ngx_http_variable_value_t, but the array contains structures, not pointers.
Additionally, ctx->var_values inspection failed to properly set var on
match.

Explicitly ignore returned value from unlink() in ngx_open_tempfile().
The only thing we could potentially do here in case of error
returned is to complain to error log, but we don't have log
structure available here due to interface limitations.

Fixed possible use of old cached times if runtime went backwards.
If ngx_time_sigsafe_update() updated only ngx_cached_err_log_time, and
then clock was adjusted backwards, the cached_time[slot].sec might
accidentally match current seconds on next ngx_time_update() call,
resulting in various cached times not being updated.
Fix is to clear the cached_time[slot].sec to explicitly mark cached times
are stale and need updating.

Win32: fixed build with Visual Studio 2005 Express.
It is available via winetricks which makes it still usable, and has
an old crtdefs.h which uses _CRT_SECURE_NO_DEPRECATE instead of
_CRT_SECURE_NO_WARNINGS to suppress warnings.

Core: ipv6only is now on by default.
There is a general consensus that this change results in better
consistency between different operating systems and differently
tuned operating systems.
Note: this changes the width and meaning of the ipv6only field
of the ngx_listening_t structure. 3rd party modules that create
their own listening sockets might need fixing.
Win32: fixed cpu hog after process startup failure.
If ngx_spawn_process() failed while starting a process, the process
handle was closed but left non-NULL in the ngx_processes[] array.
The handle later was used in WaitForMultipleObjects() (if there
were multiple worker processes configured and at least one worker
process was started successfully), resulting in infinite loop.

Fixed sorting of listen addresses so that wildcard address is always at
the end (closes #187). Failure to do so could result in several listen
sockets to be created instead of only one listening on wildcard address.
It allows to disable generation of nginx's own entity tags, while
still handling ETags in cache properly. This may be useful e.g.
if one want to serve static files from servers with different ETag
generation algorithms.
Entity tags: basic support in not modified filter.
This includes handling of ETag headers (if present in a response) with
basic support for If-Match, If-None-Match conditionals in not modified
filter.
Note that the "r->headers_out.last_modified_time == -1" check in the not
modified filter is left as is intentionally. It's to prevent handling
of If-* headers in case of proxy without cache (much like currently
done with If-Modified-Since).
Not modified filter: tests separated from actions.
This makes code more extendable. The only functional change is when
If-Modified-Since and If-Unmodified-Since are specified together, the
case which is explicitly left undefined by RFC 2616. The new behaviour
is to respect them both, which seems better.
If modification time isn't known, skip range processing and return full
entity body instead of just ignoring If-Range. Ignoring If-Range isn't
safe as client will assume entity wasn't changed since time specified.
The original idea was to optimize edge cases in case of interchangeable
backends, i.e. don't establish a new connection if we have any one
cached. This causes more harm than good though, as it screws up
underlying balancer's idea about backends used and may result in
various unexpected problems.
