When the thread is writing to the response in
RECEIVED.onWritePossible(), the execution may stop because isReady()
returned false. In this case the buffer is partially written.
When there is partially written case:
1. The state will be changed from WRITING to RECEIVED
2. A check for "write possible" will be performed:
- If onWritePossible event has been already called by the web
container while in WRITING state then this check will trigger
RECEIVED.onWritePossible() because isReady() will be true and the
writing will continue.
- Otherwise the writing will be resumed when the web container sends
onWritePossible event.
This commit adds a test runtime dependency on log4j 2 for every project
and migrates all log4j.properties files to log4j2-test.xml files.

This commit introduces initial support for JUnit Jupiter (i.e., the new
programming and extension models in JUnit 5) in the Spring TestContext
Framework.
Specifically, this commit introduces the following.
- SpringExtension: an implementation of multiple extension APIs from
JUnit Jupiter that provides full support for the existing feature set
of the Spring TestContext Framework. This support is enabled via
@ExtendWith(SpringExtension.class).
- @SpringJUnitConfig: a composed annotation that combines
@ExtendWith(SpringExtension.class) from JUnit Jupiter with
@ContextConfiguration from the Spring TestContext Framework.
- @SpringJUnitWebConfig: a composed annotation that combines
@ExtendWith(SpringExtension.class) from JUnit Jupiter with
@ContextConfiguration and @WebAppConfiguration from the Spring
TestContext Framework.

Before this commit, it was not possible to set the status code of an
HTTP response without throwing an exception if it was already
committed. The consequence was a lot of errors in the logs for long
lived HTTP exchanges like Server-Sent Events for example.
After this commit, ServerHttpResponse#setStatusCode() returns
true if the operation succeeded and false if the status code has not
been set because the response has already been committed.
In term of implementation, that makes status code managed
consistently with headers and cookies:
AbstractServerHttpResponse#setStatusCode() stores the status
code that will be effectively set later in the response lifecycle by
the HTTP server via AbstractServerHttpResponse#writeStatusCode()
when the response will be committed.
