RFR: Disable all DES cipher suites

[Jamil Nimeh]

Hello all,

This change adds all DES cipher suites to the jdk.tls.disabledAlgorithms 
Security property.  This will have the effect of making all DES-based 
suites unavailable to SunJSSE SSLSocket and SSLEngine instances, even if 
explicitly enabled using calls like SSLEngine.setEnabledCipherSuites() 
or SSLSocket.setEnabledCipherSuites().  Users wishing to re-enable these 
suites for legacy purposes must first alter the 
jdk.tls.disabledAlgorithms property in the java.security file.

Please note that prior to this change, DES-based suites were available, 
but not enabled by default on SSLSocket and SSLEngine objects.  This 
change just makes these suites no longer available without further 
intervention.

This change also removes RC4_40 from this Security property as it is 
already superseded by the RC4 identifier.  It also cleans up a 
cut-and-paste bug in a couple of the RC4_40 export suites (those suites 
are disabled already).
