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.

Fix merge problems.
---
Fixed one bug in the query_source being NULL.  

Updated test results.
---
Include more thorough profiling tests.

Improve support for prepared statements.

Use session-specific query IDs, starting at zero.
---
Selecting from I_S.profiling is no longer quashed in profiling, as
requested by Giuseppe.

Limit the size of captured query text.

No longer log queries that are zero length.

Provide the number of seconds since flush as a new status variable
named "Uptime_since_flush_status".
---
Override the post-flush value, as a second could pass between the two
statements.

           aliases ignored
When a column reference to a column in JOIN USING is resolved and a new 
Item is created for this column the user defined name was lost.
This fix preserves the alias by setting the name of the new Item to the
original alias.

  Reverted change for bug#13859, applied smaller patch from Marko

2nd version
During tmp tables cleanup we get the handler for temporary table
and delete table using handler method.

In the method Item_field::fix_fields we try to resolve the name of
the field against the names of the aliases that occur in the select
list. This is done by a call of the function find_item_in_list.
When this function finds several occurrences of the field name
it sends an error message to the error queue and returns 0.
Yet the code did not take into account that find_item_in_list
could return 0 and tried to dereference the returned value.

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

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.

For example:

$ export MYSQLD_BOOTSTRAP
$ MYSQLD_BOOTSTRAP=/path/to/full/MySQL/bin/mysqld
$ mysql_install_db
$ make test

used.

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.
