odbc_sqlconnect() stripped a trailing semicolon by writing a NUL into the Z_PARAM_STRING buffer, which is a zend_string. Shared variables, interned literals, and const values used as the DSN were permanently altered (strlen unchanged, last byte became NUL). Compute the base length instead and pass it to spprintf with %.*s, matching the non-mutating approach used when assembling UID/PWD into the connect string. Closes phpGH-22776
