These classes are meant to be extended, but the test runner
tries to run them anyway which causes a warning message to
surfaced as a test result. Making them abstract allows
them to be used by subclasses.

Explicitly set librarySearchPath of the system classloader to
"java.library.path". It used to be set implicitly by BaseDexPathClassLoader
implementation but it is no longer the case. Application classloaders
do not have access to java.library.path anymore.

So that all modifications to the cached manifest entry and to the
underlying JarVerifier are synchronized.

computedHasClassPathAttribute and hasClassPathAttribute are just cached
booleans that don't change once set, unsynchronized access to them would
cause only for them to be computed twice in the worst case.

Also, removed dead code and corresponding test.

Document that classloading with malformed certificates succeed, although
the call to getCertificates returns null.

hyts_signed_wrong_cert.jar was obtained by taking
hyts_signed.jar and changing META-INF/TEST.DSA by deleting
the first byte.

We cannot assert that HttpsURLConnection's defaultSSLSocketFactory
is the same as SSLSocketFactory.getDefault(). In the absence of calls
to HttpsURLConnection.setDefaultSSLSocketFactory, the default factory
will be the same as SSLSocketFactory.getDefault at the point at which
the first HttpsURLConnection object in the runtime is created. The
state of SSLSocketFactory can subsequently be modified via public
API to return a different default.

The best we can do is to return that the default is non-null and that
the value of getSSLSocketFactory mirrors the default. This is already
tested in libcore.javax.net.ssl.HttpsURLConnectionTest.

This reverts commit ce0115e0.

This topic has been reverted because it causes build flakiness and
bogus verification failures on most active changes.
