Also added mysql-test files:
 include/is_debug_build.inc
 r/is_debug_build.require
 r/sp-code.result
 t/sp-code.test

Since long, the compiled code of stored routines has been printed in the trace file
when starting mysqld with the "--debug" flag. (At creation time only, and only in
debug builds of course.) This has been helpful when debugging stored procedure
execution, but it's a bit awkward to use. Also, the printing of some of the
instructions is a bit terse, in particular for sp_instr_stmt where only the command
code was printed.

This improves the printout of several of the instructions, and adds the debugging-
only commands "show procedure code <name>" and "show function code <name>".
(In non-debug builds they are not available.)

my_sopen() on win32 which allows to use FILE_SHARE_DELETE flag to 
allow deleting opened files. my_sopen() implementation is added to
support this functionality.

  Corrected search for 'mysqlimport' executable

we changing current db temporarily and restore it when sp is created. however thd->db
in this case becomes empty string rather than NULL and so all checks of thd->db == NULL 
will be false. So if after this we'll issue create procedure sp2()... without specifying
db it will succeed and create sp with db=NULL, which causes mysqldto crash on 
show procedure status statement.

This patch fixes the problem.

it is added a check of not being empty value. When modifying SP with Admin 
application on win32 it does not pass curent database so sp is stored with
db=null which causes a crash later on show procedure status;

the same column as an aliased and as a non-aliased column.

The problem was that Item_direct_view_ref::eq() was first comparing view columns
by name, and in this case the name of one of them is different since it is aliased.

Indeed now that stored procedures CALL is not binlogged, but instead the invoked substatements are,
the restrictions applied by log-bin-trust-routine-creators=0 are superfluous for procedures.
They still need to apply to functions where function calls are written to the binlog (for example as "DO myfunc(3)").
We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used).
