removing some algs due to patent concerns, and rearranging

disabling RC5 at <redacted>'s request, also removing IDEA and MDC2 since the openssl FAQ on patents mentions those and we are not using them.

rearranged the code slightly to remove duplication, and added disable-gost to all of the compiles (i added that to one of them to get 1.0.1c to compile awhile back, and in the interests of uniformity it should be removed from them all).
