Only go for keep-alive if they submit a 'connection: keep-alive' header
in the request, keep behaviour the same otherwise.
The new RFC 7230 (http://tools.ietf.org/html/rfc7230#section-6.3)
states:
If the received protocol is HTTP/1.0, the "keep-alive" connection
option is present, the recipient is not a proxy, and the recipient
wishes to honor the HTTP/1.0 "keep-alive" mechanism, the
connection will persist after the current response;
Even though clients are discouraged from doing so in Appendix A.1.2
(http://tools.ietf.org/html/rfc7230#appendix-A.1.2)

This is a first step to improve the HTTP status codes returned
by Cowboy on crashes. We will tweak it over time.
Also fixes a small bug where two replies may have been sent
when using loop handlers under rare conditions.

A fix for a possible bug has been made to the original patch.

422 is undefined for HTTP and interpreted as 400.

This would allow us to override them without messing up the body,
and would make it usable with the static file handler for example.
Experimental at this point.

The options were added to allow developers to fix timeout
issues when reading large bodies. It is also a cleaner and
easier to extend interface.
This commit deprecates the functions init_stream, stream_body
and skip_body which are no longer needed. They will be removed
in 1.0.
The body function can now take an additional argument that is a
list of options. The body_qs, part and part_body functions can
too and simply pass this argument down to the body call.
There are options for disabling the automatic continue reply,
setting a maximum length to be returned (soft limit), setting
the read length and read timeout, and setting the transfer and
content decode functions.
The return value of the body and body_qs have changed slightly.
The body function now works similarly to the part_body function,
in that it returns either an ok or a more tuple depending on
whether there is additional data to be read. The body_qs function
can return a badlength tuple if the body is too big. The default
size has been increased from 16KB to 64KB.
The default read length and timeout have been tweaked and vary
depending on the function called.
The body function will now adequately process chunked bodies,
which means that the body_qs function will too. But this means
that the behavior has changed slightly and your code should be
tested properly when updating your code.
The body and body_qs still accept a length as first argument
for compatibility purpose with older code. Note that this form
is deprecated and will be removed in 1.0. The part and part_body
function, being new and never having been in a release yet, have
this form completely removed in this commit.
Again, while most code should work as-is, you should make sure
that it actually does before pushing this to production.

Adds a loop_handler test suite that runs all tests under HTTP, HTTPS,
SPDY each with and without the compress option enabled.
Fixes output filtering that used to filter more than it should have.
This forces us to parse the string sent by the emulator, which means
it's probably not perfect yet. But it should at least not hide errors
we want to see.
Fix a crash in the output filtering code that entirely disabled
output. Now when there is a crash the normal tty output is restored.
Handlers are now in test/handlers/ as they can be reused between
suites.
Only generate a single certificate for the whole ct run to speed
things up when we got many different test groups each needing
certificates.

Instead of relying on the encoding of the file we now simply
have list of numbers as they would be inside a latin1 file.

Tiny optimization.

Use cow_qs:urldecode/1 and cow_qs:urlencode/1 instead
|

Pointed out during the ConcuError tutorial by Kostis. Thanks! :-)

Before, we could have
Header: the value
is multiline
Become "the valueis multiline".
Now it will properly be "the value is multiline".

Since I made it for similar code in cowlib, let's use it here too.

The old undocumented API is removed entirely.
While a documentation exists for the new API, it will not
be considered set in stone until further testing has been
performed, and a file upload example has been added.
The new API should be a little more efficient than the
old API, especially with smaller messages.

tohexu(16) or tohexl(16) will now crash, instead of evaluating to $G or $g.

Previously if a loop handler received the timeout message from a
previous request on the same connection the socket would be set to
{active, once} incorrectly - when a socket packet was already in the
message queue. This second packet would not be added to the buffer
before a Handler:info/3 call if a user message was in the message
queue before both socket packets.

Regardless of whether a location header has been set, as explained
in the HTTP RFC.

This is an undocumented workaround to disable chunks when using HTTP/1.1.
It can be used when the client advertises itself as HTTP/1.1 despite not
understanding the chunked transfer-encoding.
Usage can be found looking at the test for it. When activated, Cowboy
will still advertise itself as HTTP/1.1, but will send the body the same
way it would if it was HTTP/1.0.
