TCM service indicates to close the TCP idle connections on
time so that the application servers do not time out on
connection and wake the modem cellular data connection up
and cost power.

This reverts behaviour introduced in 60f5406dcc094d043 where HttpEngine
doesn't attempt to recover connections on timeout / interruption. This
new behaviour introduced regressions on some devices where we're handed
a mixture of IPV4 / IPV6 routes but where only one aspect of the network
(either IPV4 or 6) is functional.

    Change Timeout.throwIfReached() to throw InterruptedIOException

    Previously this was throwing IOException, but nothing was anticipated
    that. This is slightly semantically incorrect; the thread wasn't
    interrupted. But it's much more convenient to use a single exception
    type for both timeouts.

    Also add a new type, ForwardingTimeout.

OkHttp:

Upstream commit: 4df674f8c5e2c07d881b4f2780922c7d15940814

Author: jwilson <jwilson@squareup.com>

    Don't share timeouts between pooled connections.

    This was causing crashes.

Patches applied cleanly without conflicts.

This submission will break some CTS tests due
to https://github.com/square/okhttp/issues/1552
Solutions will be made upstream and patched in.
The CTS tests broken are related to SPDY/HTTP2
which are not used by Android's embedded OkHttp.

Changes that might affect Android:
1) Cache control request headers: If-None-Match
or If-Modified-Since sent, never both.
2) Make okhttp behave more like a private, not a
shared cache.
3) SSLPeerUnverifiedException now thrown on
hostname verification errors, not IOException.

okio:

okio is now managed upstream as a separate project but has
been included here as a sub directory: the okio version here
is intended only for use with OkHttp.
okio is synced to upstream commit
82358df7f09e18aa42348836c614212085bbf045.
See okio/README.android for local changed needed to make it
compile.

okhttp:

This is effectively an upgrade from a snapshot close to
OkHttp 1.5 with Android additions to a snapshot close to
OkHttp 2.2.
okhttp was synced to upstream commit
0a197466608681593cc9be9487965a0b1d5c244c
See README.android for local changes needed to make it
compile.

Most of the old Android changes have been pushed upstream
and other upstream changes have been made to keep OkHttp
working on Android.

TLS fallback changes have not been upstreamed yet:
bcce0a3d26d66d33beb742ae2adddb3b7db5ad08
ede2bf1af0917482da8ccb7b048130592034253d

This means that some CTS tests will start to fail. A later
commit will fix those changes when it has been accepted
upstream.

There are associated changes in libcore and frameworks/base.
