summary:
  Make urllib.unquote be linear in performance, not quadratic.

Removes in-place string concatenation in the implementation of
urllib.unquote and instead uses a list to buffer writes, then joins
together. Because of mixed unicode/str issues, this implementation
avoids using the higher-level StringIO.StringIO that would manage this
buffering.

See discussion on Jython users mailing list
(http://sourceforge.net/p/jython/mailman/message/34685791/)

+r"""HTTP/1.1 client library
+
+<intro stuff goes here>
+<other stuff, too>
+
+HTTPConnection goes through a number of "states", which define when a client
+may legally make another request or fetch the response for a particular
+request. This diagram details these state transitions:
+
+    (null)
+      |
+      | HTTPConnection()
+      v
+    Idle
+      |
+      | putrequest()
+      v
+    Request-started
+      |
+      | ( putheader() )*  endheaders()
+      v
+    Request-sent
+      |
+      | response = getresponse()
+      v
+    Unread-response   [Response-headers-read]
+      |\____________________
+      |                     |
+      | response.read()     | putrequest()
+      v                     v
+    Idle                  Req-started-unread-response
+                     ______/|
+                   /        |
+   response.read() |        | ( putheader() )*  endheaders()
+                   v        v
+       Request-started    Req-sent-unread-response
+                            |
+                            | response.read()
+                            v
+                          Request-sent
+
+This diagram presents the following rules:
+  -- a second request may not be started until {response-headers-read}
+  -- a response [object] cannot be retrieved until {request-sent}
+  -- there is no differentiation between an unread response body and a
+     partially read response body
+
+Note: this enforcement is applied by the HTTPConnection class. The
+      HTTPResponse class does not enforce this state machine, which
+      implies sophisticated clients may accelerate the request/response
+      pipeline. Caution should be taken, though: accelerating the states
+      beyond the above pattern may imply knowledge of the server's
+      connection-close behavior for certain requests. For example, it
+      is impossible to tell whether the server will close the connection
+      UNTIL the response headers have been read; this means that further
+      requests cannot be placed into the pipeline until it is known that
+      the server will NOT be closing the connection.
+

-r"""HTTP/1.1 client library
-
-<intro stuff goes here>
-<other stuff, too>
-
-HTTPConnection goes through a number of "states", which define when a client
-may legally make another request or fetch the response for a particular
-request. This diagram details these state transitions:
-
-    (null)
-      |
-      | HTTPConnection()
-      v
-    Idle
-      |
-      | putrequest()
-      v
-    Request-started
-      |
-      | ( putheader() )*  endheaders()
-      v
-    Request-sent
-      |
-      | response = getresponse()
-      v
-    Unread-response   [Response-headers-read]
-      |\____________________
-      |                     |
-      | response.read()     | putrequest()
-      v                     v
-    Idle                  Req-started-unread-response
-                     ______/|
-                   /        |
-   response.read() |        | ( putheader() )*  endheaders()
-                   v        v
-       Request-started    Req-sent-unread-response
-                            |
-                            | response.read()
-                            v
-                          Request-sent
-
-This diagram presents the following rules:
-  -- a second request may not be started until {response-headers-read}
-  -- a response [object] cannot be retrieved until {request-sent}
-  -- there is no differentiation between an unread response body and a
-     partially read response body
-
-Note: this enforcement is applied by the HTTPConnection class. The
-      HTTPResponse class does not enforce this state machine, which
-      implies sophisticated clients may accelerate the request/response
-      pipeline. Caution should be taken, though: accelerating the states
-      beyond the above pattern may imply knowledge of the server's
-      connection-close behavior for certain requests. For example, it
-      is impossible to tell whether the server will close the connection
-      UNTIL the response headers have been read; this means that further
-      requests cannot be placed into the pipeline until it is known that
-      the server will NOT be closing the connection.

summary:
  Better mgmt of lifecycle in ThreadState and PySystemState. Fixes #2321, #2404

ThreadStateMapping tracks the relationship of ThreadState and
java.lang.Thread objects so that ThreadState can be used to augment
threads with additional information needed for Python semantics (a
classic canonical mapping). Indirectly, this augmentation includes
PySystemState, which is exposed to Python code as the sys
module. However if threads are live longer than
ThreadState/PySystemState, as seen in certain app servers for example,
we need to maintain weak relationship to avoid ClassLoader resource
leaks. Previous work to fix #1327 was too aggressive in avoiding this
coupling, which had impact on the public API of the Jython
runtime. Rather than requiring this API to be changed, this commit
dfixes this issue by using a ReferenceQueue to determine when a
PySystemState is no longer referenced outside of a Python call stack,
which means the corresponding ThreadState can be cleaned up.

Based on this PR from Jan Vorwerk
https://bitbucket.org/jython/jython/pull-requests/62/suggested-fix-for-2321/

Also adds a test based on one proposed by Eli Oxman in #2404.

summary:
  Support "readall" on files reported as having size=0. Fixes #2358

On Linux for files in the /proc virtual filesystem, nearly all files
have a reported size of zero. Previously the implementation of
"readall" functionality (eg, file.read()) depended on this size as
being accurate. Now if the size=0, Jython attempts to read the file in
chunks.

summary:
  Load default CA certs on Java 9 (#2390); and passing cert, key into engine (#2437)

Java 9 has a slightly different layout of installed CA certs. Also now
passes cert and key files, if specified from the wrapping call, into
the underlying SSL engine.

summary:
  Upgrade bundled jars in extlibs to latest, excluding those requiring pinning

Maven coordinates for upgraded jars:

    com.github.jnr:jffi:1.2.10
    com.github.jnr:jnr-constants:0.9.0
    com.github.jnr:jnr-ffi:2.0.7
    com.github.jnr:jnr-netdb:1.1.5
    com.github.jnr:jnr-posix:3.0.23
    com.google.guava:guava:19.0
    com.ibm.icu:icu4j:56.1
    jline:jline:2.13
    org.apache.commons:commons-compress:1.10
    org.bouncycastle:bcpkix-jdk15on:1.54
    org.bouncycastle:bcprov-jdk15on:1.54

Currently we have to pin Antlr to 3.13 and ASM to 5.0.3 until we fix
parsing and compilation respectively.

Also removed a unused jars in extlibs: libreadline-java-0.8.jar,
profile.jar

We plan to stop bundling all extlibs jars (except perhaps precompiled
JFFI stubs for each architecture) in Jython 2.7.2; see #2182
