- mclient's executing time profiling options and output format have
  been changed. Instead of implicitly via the "--interactive"/"-i"
  option (or when using and interactive mclient console), execution time
  profiling is now controlled via an explicit "--timer=timermode"/"-t
  timermode" command-line option, or a "\t timermode" command in the
  interactive mclient console. The default (also in the interactive
  mclient console) is now timermode "none", i.e., no timing information
  is given. Timermode "clock" activates client-side wall-clock timing
  ("clk") in "human-friendly" format much like the interactive mode did
  before. Timermode "performance" also provides detailed server-side
  timings: "sql" is the time to parse the SQL query, optimize the
  logical relational plan and create the initial physical (MAL) plan;
  "opt" is the time to optimize the physical (MAL) plan; "run" is the
  time to execute the physical (MAL) plan. With timermode "performance"
  all server-side timings and the client-side wall-clock time are given
  in milliseconds (ms). Note that the client-measured wall-clock time
  "clk" is reported per query only when options "--interactive" or
  "--echo" are used, because only then does mclient send individual
  lines (statements) of the SQL script to the server. Otherwise, mclient
  sends the SQL script in large(r) batch(es) to the server, and, thus,
  only the total wall-clock time per batch is measured and reported. The
  server-measured detailed performance timings "sql", "opt", "run" are
  always measured and reported per query. Also, all timing information
  is now given on a separate line and set to stderr rather than stdout.

- Some types and constants were moved from configure (and hence
  monetdb_config.h) to gdk.h.  In particular, the types "lng" and
  "ulng" have been moved and can therefore no longer be used by code
  that doesn't (ultimately) include gdk.h.  Just use int64_t instead.
  A bunch of format defines have been removed: SZFMT, SSZFMT, PTRFMT,
  PDFMT.  Just use the C standard codes for those (%zu, %zd, %p, %td).
  The define for printing a lng (LLFMT) was also moved.  Use PRId64 for
  printing int64_t in code not using gdk.h.  Removed all references to
  __int64 and long long (use int64_t instead).
