In many cases, binaries can no longer dump core after calling setuid().

Where the PR_SET_DUMPABLE macro is set, use the prctl() system call 
to tell the kernel that it's allowed to dump the core of the server.


configure.in:
  Test system for "sys/prctl.h", to get access to prctl().
sql/mysqld.cc:
  Add a process-control operation that tells the Linux kernel that it 
  is allowed to dump core after setuid().

	DragonflyBSD misc patches

The bug reporter anticipated a problem, instead of experiencing one.

IRC conversation:
<xtraeme> sem_init is defined in librt on NetBSD
	solaris uses libposix4 iirc
	that's why I sent a patch
<chadmiller> xtraeme: Agreed.  But, AFAICT, mysql doesn't use 
	sem_init() anywhere.  Thus my confusion.
<xtraeme> I didn't verify that, but I saw that sem_init wasn't detected 
	correctly...
	why are you checking for sem_init if it's unused then? :-)
<chadmiller> xtraeme: In recent autoconf scripts, we change it to test 
	for sched_yield() .
<xtraeme> that's ok then
	sched_yield is in libc
	feel free to close the bug report then :-)


configure.in:
  Remove useless test for sem_init() .

	DragonflyBSD misc patches

Add the original intended test, since our current test for sched_yield
is insufficient to copy.


configure.in:
  We can't check for sched_yield, as that is in libc on FBSD.
  
  Re-add the check for sem_init in librt.

mysqldump didn't properly handle getting no data on
SHOW CREATE PROCEDURE.  If S/C/P fails (due to dumping
user's insufficient privileges on mysql.proc, say),
mysqldump will print a comment to that effect to the
output and return an error-code.  If the -f (force) option
is used, the dump will continue, otherwise, it will abort
right there and then.

Also fixes Bug#22761, "mysqldump reports no errors when using
--routines without mysql.proc privileges"

some rollup rows (rows with NULLs for grouping attributes) if GROUP BY
list contained constant expressions.

This happened because the results of constant expressions were not put
in the temporary table used for duplicate elimination. In fact a constant
item from the GROUP BY list of a ROLLUP query can be replaced for an
Item_null_result object when a rollup row is produced . 

Now the JOIN::rollup_init function wraps any constant item referenced in
the GROYP BY list of a ROLLUP query into an Item_func object of a special
class that is never detected as constant item. This ensures creation of
fields for such  constant items in temporary tables and guarantees right
results when the result of the rollup operation first has to be written
into a temporary table, e.g. in the cases when duplicate elimination is
required.

  Itroduced class Item_func_rollup_const derived from Item_func. The object of
  this class are never detected as constant items.
  We use them for wrapping constant items from the GROUP BY list of any ROLLUP
  query. This wrapping allows us to ensure writing constant items into temporary
  tables whenever the result of the ROLLUP operation has to be written into a
  temporary table, e.g. when ROLLUP is used together with DISTINCT in the SELECT
  list.
