Allows language_range/2 to parse RFC5646 language codes.
Cleanup the configuration handling in http_SUITE
Enable Autobahn Test Suite by default

Includes a variety of small changes that are a first step to
improving the test system heavily.
Silence expected test error reports from the console output

The errors are still logged by common_test to the report it creates.
The process that is going to crash has to call cowboy_error_h:ignore/3
with the MFA where the crash is expected to occur for it to be ignored.
Gun retry failures are also ignored. Only unexpected crashes are printed.
Start applications directly from the ct hook
Move listener initialization to cowboy_test
Fix two issues where listeners didn't get stopped properly
Make loop handlers work with SPDY

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.

Add request body reading options

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.
Add a return value to onresponse hook to override status/headers

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.
Add a simple multipart upload example
Add a REST principles chapter to the guide

This is a complex subject so hopefully I did not introduce
errors while trying to explain it.
