MIME: added application/font-woff MIME type (ticket #292).
MIME: added the most common OOXML MIME types (ticket #243).
MIME: eot MIME type updated to follow IANA (ticket #306).
Fixed try_files with empty argument (ticket #390).
Upstream: posted requests handling after ssl handshake errors.

Missing call to ngx_http_run_posted_request() resulted in a main request hang
if subrequest's ssl handshake with an upstream server failed for some reason.

Reported by Aviram Cohen.
Cache: lock timeouts are now logged at info level.
Configure: pcre.lib dependencies fix.

Previously, an attempt to build pcre.lib on win32 before anything else
failed due to no pcre.h.
Updated PCRE used for win32 builds.

As of PCRE 8.33, config.h.generic no longer contains boolean macros.  Two
of them (SUPPORT_PCRE8 and HAVE_MEMMOVE) were added to appropriate makefiles.
This allows PCRE 8.33 to compile and don't change anything for previous
versions.
