Fixed the yassl base64 decoding to correctly allocate a maximum decoded buffer size. 


mysql-test/std_data/server8k-cert.pem:
  BitKeeper file /Users/dkatz/50/mysql-test/std_data/server8k-cert.pem
mysql-test/std_data/server8k-key.pem:
  BitKeeper file /Users/dkatz/50/mysql-test/std_data/server8k-key.pem
extra/yassl/taocrypt/src/coding.cpp:
  Fixed buffer allocation to compute the proper maximum decoded size: (EncodedLength * 3/4) + 3
mysql-test/r/ssl_8k_key.result:
  New BitKeeper file ``mysql-test/r/ssl_8k_key.result''
  
  Test connection to server using large SSL key.
mysql-test/t/ssl_8k_key.test:
  New BitKeeper file ``mysql-test/t/ssl_8k_key.test''
  
  Test connection to server using large SSL key.
