used to mark entries after recovering a tracing log from a previous session.

tracing buffer entries even when not in the kernel debugger.

* Fixed TraceEntryIterator::Current(): If fEntry was NULL, it would
return 0x4.

compatible with what our code assumed (pointers to objects of
TraceEntry and its POD base class trace_entry aren't identical
anymore).
* Added optional stack traces for ktrace_printf() output in the kernel.

* Added capture_tracing_stack_trace() which allocates space in the
tracing buffer and captures the stack trace according to the given
parameters.
* Added TraceOutput::PrintStackTrace() to print a stack trace thus
created.
* Added TraceEntry::DumpStackTrace() callback which is supposed to print
a stack trace for the entry, if it can do that.
* Added "--stacktrace" switch to the "traced" command, which causes the
stack traces for all entries that have one to be printed as well.

kernel and added a WrapperTraceFilter* parameter, which allows for
additional filtering. This way other commands can print tracing output
with special filtering.

finally created a solution to avoid that: Header files that contain
configuration settings (and nothing else) go to build/config_headers.
To change settings, create a directory build/user_config_headers (which
is ignored by svn), copy the respective header there and modify it at
your leisure. Currently only tracing_config.h has been moved to the new
location, but more files will follow eventually. It is also recommended
to move optional macro definitions in Jamfile (as for BFS) to a config
header instead; the build system will then automatically rebuild on
changes.

TraceOutput for output options instead.
* Added "traced" option --difftime. Instead of the absolute system time
it prints the difference time to the previously printed entry.

is recorded in a kernel trace entry (if tracing is enabled).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23686 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added "printteam" switch to "traced" command, enabling the printing of
the team ID.
* Added "team" filter to the "traced" command expression language.

write code aligned to what one has written in the comment (or the
other way around).
* Made trace_entry structure doubly linked, by introducing a
previous_size member. By using bit fields, shrinking the flags field
to 4 bits, and not saving the lower two bits of size and previous_size
(which are always 0 due to alignment), the structure remains 4 byte
sized and can still address the same entry size.
* kBufferSize is no longer one less than it could be.
* "traced" command:
- Use static variable for the iteration state rather then cluttering
the temporary debug variable name space.
- The <count> parameter can now be negative, in which case the entries
before (and including) <start> are printed.
- Added a new optional parameter, specifying the maximal number of
entries to be filtered. Filtered iteration is beautifully
comfortable now.

boolean operators ("not", "and", "or") and filters matching thread IDs
or contained strings.
I'm still not fully happy with the command. It should be possible to
define a filter and then comfortably scroll through the matching
entries. Currently having to specify an index range of the unfiltered
entries is rather unhandy in combination with filtering.

So now there's a central place to enable tracing in general and for
individual components.

* Added function to allocate space in the buffer.
* Dump() now fills a buffer instead of printing its data directly.
* This allows the new "#pattern" argument of the "traced" command to
work. When you're using that, the index of the trace entry is printed
out, too, so that you can then get a full dump around the hits.
* Added an AddDump() method to the AbstractTraceEntry class so that
there is no need to call the inherited function anymore.
* Minor cleanup.

will not accept if the allocator returns NULL and crashes instead
(ie. not compiling in tracing would have crashed if some module tried
to use it).
* Added total entries count to the KDL command output.
* Fixed computing the start index of the KDL command.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23460 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented an optional tracing layer that can be used in the kernel.
Nice to use if you don't have serial output or need something that doesn't
slow down the system as much.
