In Mac OS X Lion, Apple deprecated the use of the system OpenSSL library
in favour of their CommonCrypto library.  This change adds a work-around
that allows nginx to still be built on Lion with OpenSSL.
Fix of case when start sample does not reside on chunk boundary.
Skipping traks with unsupported media formats.
Bugfix: open_file_cache did not update file info on retest.

If file inode was not changed, cached file information was not updated
on retest.  As a result stale information might be cached forever if file
attributes was changed and/or file was extended.

This fix also makes obsolete r4077 change of is_directio flag handling,
since this flag is updated together with other file information.
Fix of the previous commit: is_directio flag processing introduced in r4077
is still worthwhile.
nginx-1.1.3-RELEASE
Version bump.
Fixing building by gcc-4.7.
Style fix.
Fix of struct field name.
- The module name is now also output as an HTML header.
- Agreed that examples can only contain literal text.
- Agreed to call modules "ngx_*_module".
- Renamed XML element "http-error" to a more general "http-status".
- Fixed text of error codes to match the actual code.
Regenerated after previous commit.
Added ngx_http_mp4_module documentation.
Regenerated after previous commit.
MP4 co64 atom support added.
Buffers reuse in chunked filter.

There were 2 buffers allocated on each buffer chain sent through chunked
filter (one buffer for chunk size, another one for trailing CRLF, about
120 bytes in total on 32-bit platforms).  This resulted in large memory
consumption with long-lived requests sending many buffer chains.  Usual
example of problematic scenario is streaming though proxy with
proxy_buffering set to off.

Introduced buffers reuse reduces memory consumption in the above problematic
scenario.

See here for initial report:

API change: ngx_chain_update_chains() now requires pool.

The ngx_chain_update_chains() needs pool to free chain links used for buffers
with non-matching tags.  Providing one helps to reduce memory consumption
for long-lived requests.
Workaround for cpu hog on errors with cached connections.

Just doing another connect isn't safe as peer.get() may expect peer.tries
to be strictly positive (this is the case e.g. with round robin with multiple
upstream servers).  Increment peer.tries to at least avoid cpu hog in
round robin balancer (with the patch alert will be seen instead).

This is not enough to fully address the problem though, hence TODO.  We
should be able to inform balancer that the error wasn't considered fatal
and it may make sense to retry the same peer.
Upstream: separate pool for peer connections.

This is required to support persistent https connections as various ssl
structures are allocated from connection's pool.
Upstream: content_length_n API change.

We no longer use r->headers_out.content_length_n as a primary source of
backend's response length.  Instead we parse response length to
u->headers_in.content_length_n and copy to r->headers_out.content_length_n
when needed.
