The DOF file output by dtrace -A contains only the loadable sections.
However, as it was created by a call to dtrace_dof_create() without
flags, the original DOF was created with the loadable sections. The
result is that the DOF includes the section headers for the unloadable
sections (COMMENTS and UTSNAME) without these sections actually being
present. This is inconsistent.
A simple change to anon_prog() ensures that the missing sections are
present in the outputted DOF. Alternatively, the call to
dtrace_dof_create() could pass the DTRACE_D_STRIP flag stripping out the
loadable sections. As the unloadable sections contain info useful for
debugging purposes they haven't been stripped.

server in the background. However, when running in the background,
stdin is closed and ncat initiates a graceful shutdown of the SCTP
association. This is not expected by the client. Therefore, the
ncat-based discard server is replaced by a perl-based one.
In addition, to remove the dependency from ncat, which needs to be
installed via the nmap port, also the code testing for a free SCTP port
is changed to use the perl-based client.
Finally, remove some debug output from the report generated.

The code imported from opensolaris was depending on ping supporting
UDP for sending probes. Since this is not supported by ping on FreeBSD
use a perl script instead.
The remote test requires the usage of ksh93, so state that in the

Enable the local test, but keep the remote test disabled, since it

We can't link an executable using -m32 until the lib32 phase of a
buildworld, though the build works fine when executing make from
cddl/usr.sbin/dtrace/tests. Some other solution will need to be found.
- The exit probe was not appropriately filtered to only the known pid so it
was firing on any random process that would exit rather the only the one
we cared about.
- The dtest script executes the tst.raise*.exe in the background from
POSIX sh without jobs control. POSIX mandates that SIGINT be set to
SIG_IGN in this case. The test executable never actually tested that
SIGINT could be caught despite trying to block and delay the signal.
So the SIGINT sent from raise() is never actually received since it
is ignored. This could be fixed by calling 'trap - INT' from dtest
before running the executable but I've opted to just use SIGUSR1
instead in these specific tests rather than adding more logic to
test that SIGINT is not ignored at startup.
These 2 issues meant that the tests would randomly work but only if a process
coincidentally exited during the test.

It seems that currently normalization of stddev aggregation is done
incorrectly.
We divide both the sum of values and the sum of their squares by the
normalization factor. But we should divide the sum of squares by the
normalization factor squared to scale the original values properly.
