* Fix two problems with the auto_reloader in Linux.
1) Change 'posix' to 'linux' in sys.plaform check, because 'posix' is an invalid value and 'linux' is the correct value to use here.
2) In kill_process_children, don't just kill the 2nd level procs, also kill the 1st level procs.
Also in kill_process_children, catch and ignore errors in the case that the child proc is already killed.
* Fix flake8 formatting on PR
The Canceled exception handler purposely sets `response` to `None` to drop references to the handler coroutine, in an attempt to preemptively release resources.
This commit also fixes a possible reference-before-assignment of the `response` variable in the `handle_request` function.
Finally, another byproduct of this change is that ResponseMiddleware will no longer run if the `response` is `None`.
* Add content_type flag to Sanic.static
Fixes#1266
* Fix flake8 error in travis
Add line to document `content_type` arg
* Fix content_type for file streams
Update tests

* Remove content_type as an arg to HTTPResponse
`response.HTTPResponse` will default to `headers['Content-Type']` instead of `content_type`

* URL Quote the URL before redirecting
* Use safe url instead of unsafe one
* Fix query params
* fix build
* Whitelist all reserved characters from rfc3986
* Add tests for redirect url sanitizing
* Remove check for resulting URL on header injection test
The thing the tests are testing for can be implemented in other
ways that don't redirect to 100% the same address, but they'll all have
to match the remaining parts of the test to succeed.
* add unit tests, which should fail
* fix CIDict
* moving CIDict to avoid circular imports
* fix unit tests
* use multidict for headers
* fix cookie
* add version constraint for multidict
* omit test coverage for __main__.py
* make flake8 happy
* consolidate check in for loop
* travisci retry build
* introduced basic entity and hopbyhop header identification
* removed entity headers
* coding style fixes
* remove unneeded header check
* moved from bytes to unicode in headers
* changed list to tuple in empty response statuses
causes a route to be added twice. One without the slash, the other with the
Setting strict_slashes to false when a route does not end with slashes
slash. This is ok if the Router._add method runs linearly, but problematic
when it runs recursively. Unfortunately recursion is triggered when
the host param to the Router._add function is a list of hosts.
A field name in the Content-Disposition header is required by the multipart/form-data spec. If one field/part does not have it, it will be omitted from the request. When this happens, we log it to DEBUG.
Sanic automatically assumes that a form field is a file if it has a content-type header, even though the header is text/plain or application/json. This is a fix for it, I took into account the RFC7578 specification regarding the defaults.
When passing a null value as parameter (ex.: 0, None or False), Sanic said "Error: Required parameter `param` was not passed to url_for"
Example:
```
@app.route("/<idx>")
def route(rq, idx):
pass
```
```
url_for("route", idx=0)
```
No longer raises: `Error: Required parameter `idx` was not passed to url_for`
Change auto reloader enviroment varible name to SANIC_SERVER_RUNNING
Fix some typo mistakes, flake uncompatibilities and such problems.
Raise NotImplementedError for operating systems except posix systems for auto reloading.
Before: Even after raising ResponseTimeout, server still processes
remaining tasks until it is done
After: Before raising ResponseTimeout, server stops working task.
