Warning: INCOMPATIBLE CHANGE
The module now outputs JSONP by default. To restore the old behavior
one need to add "upload_progress_java_output" to the progress
probe location.

This release is compatible with nginx 1.1.15

Nginx 1.1.15 removed the NGX_PARSE_LARGE_TIME error code.
The code checking this error is not used anymore, so let's remove
it.

This should fix the compilation error when compiling with the
-Wunused-but-set-variable gcc option.

Due to the done flag not being correctly set to 0 when the error
tracker triggers, it could happen that such upload could be mistakenly
removed from the the rbtree that contains all in-flight uploads.
Thanks to Theo Cushion for finding this issue.

It could happen that when several keys produces the same hash that
find_node was not trying hard enough to traverse the rb tree.

Added an 'upload_progress_jsonp_output' directive that sets templates that work with jsonp.
Make jsonp parameter name configurable with the 'upload_progress_jsonp_parameter' directive.

Some uninitialized memory could lead to non array allocation in scripts,
leading to a segfault when reloading nginx.

It was impossible to inherit the templates from an higher config level,
because the templates were overwritten when the config were merged.

* global templates were not inited before their use
* relying on unpushed array made nelts == 0 and no array use
* code deduplication when initializing global templates

This could happen with the upload module if for a reason the upload
is aborted. In this case an internal redirect is done, but the request
still contains our read even handler.
Unfortunately the request args are nullified before calling this read
even handler. So we were crashing because we didn't check for id==null.
This patch fixes this issue.

When we clean a node, we ask nginx to free the memory. On some
platform or no load there were great chance the memory wasn't
reused for something else.
With high load and on FreeBSD, the memory seems to be reused
immediatly and we jump in the middle of f*****g nowhere, and
we crash.

Thanks to Vladimir Getmanshchuk for his bug report.

This was due by reusing slabs from a terminated upload without reseting the
various parameters including the done parameter.
