Bug#24795: SHOW PROFILE

Profiling is only partially functional on some architectures.  Where 
there is no getrusage() system call, presently Null values are 
returned where it would be required.  Notably, Windows needs some love 
applied to make it as useful.

  Syntax this adds:
  
  SHOW PROFILES
  
  SHOW PROFILE [types] [FOR QUERY n] [OFFSET n] [LIMIT n]
   where "n" is an integer
   and "types" is zero or many (comma-separated) of
      "CPU"
      "MEMORY" (not presently supported)
      "BLOCK IO"
      "CONTEXT SWITCHES"
      "PAGE FAULTS"
      "IPC"
      "SWAPS"
      "SOURCE"
      "ALL"

It also adds a session variable (boolean) "profiling", set to "no"
by default, and (integer) profiling_history_size, set to 15 by 
default.

This patch abstracts setting THDs' "proc_info" behind a macro that 
can be used as a hook into the profiling code when profiling 
support is compiled in.  All future code in this line should use
that mechanism for setting thd->proc_info.

---

Tests are now set to omit the statistics.

---

Adds an Information_schema table, "profiling" for access to 
"show profile" data.

- configure --disable-grant-options defines DISABLE_GRANT_OPTIONS
- configure.js/cmake also updated
- if DISABLE_GRANT_OPTIONS is defined, mysqld no longer recognizes:
  --bootstrap

Scripts which rely on those three options are modified to check the environment for MYSQLD_BOOTSTRAP; it should be set to the full path of a mysqld which does handle those options.

$ mysql_install_db
$ make test

The Item::save_in_field() function is called from fill_record() to fill the 
new row with data while execution of the CREATE TABLE ... SELECT statement.
Item::save_in_field() calls val_xxx() methods in order to get values.
val_xxx() methods do not take into account the result field. Due to this
Item_func_set_user_var::val_xxx() methods returns values from the original
table, not from the temporary one.

The save_in_field() member function is added to the Item_func_set_user_var
class. It detects whether the result field should be used and properly updates
the value of the user variable.

A BINARY field is represented by the Field_string class. The space character
is used as the filler for unused characters in such a field. But a BINARY field 
should use \x00 instead.

Field_string:reset() now detects whether the current field is a BINARY one
and if so uses the \x00 character as a default value filler.
