lang/seed7: update to 05_20170501

With this update, lang/seed7 depends on a number of database client libraries
(MySQL, SQLite, unixODBC and PostgreSQL). The reason for this is that the
configuration stage doesn't allow to specify which database drivers to use, but
rather automatically links against what's installed. This would cause
non-tracked dependencies in the case the user building the port happens to have
any of the drivers installed at build time.

20170501:
- The example program diff7.sd7 has been added. This program compares
  two files line by line.
- The example program hd.sd7 has been added. This program writes a
  hexdump of a given file.
- The functions sha384 and sha512 have been added to msgdigest.s7i.
- The compiler has been improved to optimize expressions like
  bin64(aBigExpression mod aPowerOfTwo).
- The library vectorfont.s7i has been improved to allow scaling of
  vector fonts.
- The dialog element passwordField has been added to cgidialog.s7i.
  The passwordField dialog element allows entering a password without
  readable echo.
- The function readPassword has been added to editline.s7i.
- In array.s7i the for-until loops for arrays have been improved to
  work correct, when the until-condition uses the for variable.
- In cli_cmds.s7i the functions getCommandParameter,
  getUnixCommandParameter and getDosCommandParameter has been
  improved to recognize when a closing quote is missing.
- In cli_cmds.s7i in the function processCommand the handling of
  external commands with redirection of stdin has been improved.
- The functions xyArray and scale have been added to graph.s7i.
- In seed7_05.s7i the exception DATABASE_ERROR has been introduced.
- The programs sql7.sd7 and chkdb.sd7 have been improved to use the
  new exception DATABASE_ERROR.
- A parse operator for dbCategory has been added to sql_base.s7i.
- The pictures return_pic and right_arrow_pic have been added to
  pic32.s7i and pic16.s7i.
- The function checkBinBinaryWithBigMod has been added to chkbin.sd7.
  This function checks the optimizations done with expressions like
  bin64(aBigExpression mod aPowerOfTwo).
- In tls.s7i the type securityParameters has been renamed to
  tlsParameters. The functions showMsg and showMsgType have been
  renamed to showTlsMsg respectively showTlsMsgType.
- In tls.s7i the generation of CLIENT_HELLO, SERVER_HELLO,
  CERTIFICATE, SERVER_HELLO_DONE, CLIENT_KEY_EXCHANGE,
  CHANGE_CIPHER_SPEC, FINISHED, ALERT and APPLICATION_DATA messages
  has been improved.
- In int_act.s7i the types addSubElementType and
  addSubElementListType have been renamed to addSubIntElementType
  respectively addSubIntListType.
- In the compiler (in big_act.s7i, function process_const_big_mod)
  the handling of the bigInteger mod operator, when the divisor is a
  power of two, has been improved. Now a temporary result is freed.
- In the compiler (in big_act.s7i, function process_const_big_mult)
  the handling of the bigInteger multiplication with a negated power
  of two has been improved. Now a temporary result is freed.
- The functions generateAddSubParamList and evaluateConstants have
  been added to comp/big_act.s7i.
- The function optimize_bin_binary_of_big_mod has been added to the
