* lib/rubygems:  Apply the following security fixes to RubyGems 1.3.7:

  RubyGems now disallows redirection from HTTPS to HTTP.

  RubyGems now verifies SSL connections.

  Patch by Hiroshi Nakamura.
* test/rubygems:  ditto.

* ext/openssl/ossl_ssl.c: Add SSL constants and allow to unset SSL
  option to prevent BEAST attack. See [Bug #5353].

  In OpenSSL, OP_DONT_INSERT_EMPTY_FRAGMENTS is used to prevent
  TLS-CBC-IV vulunerability described at
  http://www.openssl.org/~bodo/tls-cbc.txt
  It's known issue of TLSv1/SSLv3 but it attracts lots of attention
  these days as BEAST attack. (CVE-2011-3389)

  Until now ossl sets OP_ALL at SSLContext allocation and call
  SSL_CTX_set_options at connection.  SSL_CTX_set_options updates the
  value by using |= so bits set by OP_ALL cannot be unset afterwards.
  This commit changes to call SSL_CTX_set_options only 1 time for each
  SSLContext. It sets the specified value if SSLContext#options= are
  called and sets OP_ALL if not.

  To help users to unset bits in OP_ALL, this commit also adds several
  constant to SSL such as
  OpenSSL::SSL::OP_DONT_INSERT_EMPTY_FRAGMENTS.  These constants were
  not exposed in Ruby because there's no way to unset bits in OP_ALL
  before.

  Following is an example to enable 0/n split for BEAST prevention.

    ctx.options = OP_ALL & ~OP_DONT_INSERT_EMPTY_FRAGMENTS

* test/openssl/test_ssl.rb: Test above option exists.

--
* vm_insnhelper.c (vm_call_bmethod): fix to hook call/return event
  for methods defined by define_method().
* thread.c (call_trace_proc): Fix to skip if class is not given (0).
  Note that ID and Class object are passed for call/return event
  if the called method was defined by define_method().
  If you are author of tracer/profiler/debugger, this may be an
  important change.  You should check passed class as zero or
  non-zero instead of checking the event type.
* test/ruby/test_settracefunc.rb: add a test for above.
