events. The probes mirror many of the SNMP statistics defined
in /usr/include/linux/snmp.h. Each probe represents a single SNMP
statistic or MIB. Each of the probe's handler is called when system
performs an operation that would alter the associated statistic. Along
with each probe is defined an indexed set of counters used to record
probe hits. The probe handlers call a user supplied callback functions
to determine which counter to alter. The user's callback should returns a
key value that will be used to index the counter. For example a callback
could return a unique value for each socket. This would results in a
separate counter being used for each socket.
tcpipstat.stp shows how snmp tapsets could be used. Tcpipstat collects and
displays network statistics related to individual TCP sockets or groups of
sockets. The statistics that are collected are simmer to that of the command
netstat -s, only sorted and grouped by individual sockets.

This only happened if there was a lot of cruft in the testsuite dir since
expect wasn't "draining" the output of the spawned ls command for some
reason. Work around it by just using tcl file globs to match.

For shared libraries (.dynamic sections) we need the eh frame section
address offset. This is the sh_addr if the shared library isn't prelinked
(since the base load address is zero in that case), otherwise it is
the module start address minus the bias (which also works for the
non-prelinked case).
* translate.cxx (get_unwind_data): Adjust eh_addr for module start and
bias if module isn't absolute (has no relocations).
* testsuite/systemtap.exelib/ustack.tcl: Accept all prelink tests.

g++ is also supported but disabled because it didn't add much interesting
differences in binaries and exploded the test search case a bit.

keep support for enabling it.

We split debuginfo before prelinking, that means that the base load address
of the .so is non-zero, while for the .debug files they are zero. In the
other case we supported sep-debug without prelinking both .so and .debug
load bases were zero. In this new test case both base load addresses are
non-zero.
* testsuite/systemtap.exelib/exelib.exp: Add libdebug == "sep-after" to
indicate separate debuginfo after prelinking library. Skip sep-after
if not prelinking.
