ECPGdeallocate_all(), ECPGprepared_statement(), ECPGget_desc(), and ecpg_freeStmtCacheEntry() could crash with a SIGSEGV when called without an established connection (for example, when EXEC SQL CONNECT was forgotten or a non-existent connection name was used), because they dereferenced the result of ecpg_get_connection() without first checking it for NULL. Each site is fixed in the style of the surrounding code. New tests are added for these conditions.
