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.

	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 :-)

	DragonflyBSD misc patches

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

The message is gramatically wrong, and factually wrong.

Change it to refer to the myisam_sort_buffer_size variable and change
"to" to "too".

Warnings may show up in the error log that complain about a table, yet
don't tell us which table.

Add the database and table names to the message.

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.

If isinf() is not available on a target platform, use our own imlementation via finite() and isnan(). If either of the last two is not available as well, use simple replacements which are platform-neutral, but slower than compiler intrinsics.
