Changes 5.5.48:
* yaSSL was upgraded to version 2.3.9. This upgrade corrects an issue in which \ 
yaSSL handled only cases of zero or one leading zeros for the key agreement \ 
instead of potentially any number, which in rare cases could cause connections \ 
to fail when using DHE cipher suites.
* The Valgrind function signature in mysql-test/valgrind.supp was upgraded for \ 
Valgrind 3.11.
* Bugs Fixed
