* user_debug_break_or_watchpoint_hit() into separate functions for
break- and watchpoints. The one for breakpoints gets another parameter
which indicates whether the breakpoint was a soft- or hardware
breakpoint. This info is also sent to the debugger.

* Changed the index-based lookup of strings for debug message and
exception codes to a search through entry lists. A bit slower, but more
robust with respect to changes of the underlying enumerations.

Most of the debug events had their own message, but some were grouped
into this `stopped' message with a `why' field to describe what kind
of event it actually was. Hence the user had to check two levels until
they could know what event occurred. So I got rid of this message and
provided separate messages for the concerned events.
* Got rid of B_DEBUG_MESSAGE_GET_WHY_STOPPED and introduced
B_DEBUG_MESSAGE_GET_CPU_STATE which is pretty much the same.
* Put B_DEBUG_MESSAGE_RUN_THREAD and B_DEBUG_MESSAGE_STEP_THREAD into
a single B_DEBUG_MESSAGE_CONTINUE_THREAD message with a boolean
`single_step' field.
* get_debug_why_stopped_string() -> get_debug_message_string().

changes.
RootLayer.cpp: window tab was properly lit only when changing focus with
the mouse. Now the same happens when showing or hidding windows.
Desktop.cpp: normal windows created after floating windows did not had
B_FLOATING_APP_WINDOW_FEEL windows in their internal list, thus when such
a window was selected to become the front most it did not show floating
app windows in front of it. Fixed that now.

(there's a separate B_DEBUGGER_MESSAGE_EXCEPTION_OCCURRED now).

condition when the traced team exits, but this seems to be a inherent
problem. The thread that calls _kern_exit_team() apparently still manages
to send the post-syscall message, but when the debugger tries to continue
it, it is already gone. Not really harmful. We'll probably find a remedy
later.

* No longer kill the time when a page fault occurs, but rather send a
SIGSEGV.

of a signal.
* Added sigaction_etc(). It's just a sigaction() for which the thread
in question can be specified.

not to be notified.
* Added debugger commands for setting/getting of thread signal ignore
masks and signal handlers.
* Renamed user_debug_fault_occurred() to a more correct
user_debug_exception_occurred(). It no longer sends a `stopped' message,
but the new one dedicated to exceptions. Additionally the number of the
signal is supplied that will be sent, when the thread continues (without
indicating to ignore the event).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11703 a95241bf-73f2-0310-859d-f6bbb57e9c96
get_debug_exception_string() to get a user-readable string for an
exception type.
* Added more signal support. Now the debugger can set per thread which
signals it wishes to be notified of. It can also just ignore the next
occurrence of a signal.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11701 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added support for debugger handover. The current debugger need to send
a B_DEBUG_MESSAGE_HANDED_OVER message. The rest is completely
transparent to the new debugger. It simply calls install_team_debugger().
* Implemented _user_wait_for_debugger().
* Reworked a few bits to ensure that after a remove_team_debugger() or
after requesting a debugger handover the debugger doesn't get any more
messages.
* When the debugger is removed or dies, the debugged threads should now
cleanup their debug info and continue, instead of waiting at their
debug port forever.
All the new features are not tested. Will happen, when gdb will be
debugged.

(new `flags' parameter, flag B_WAIT_TILL_LOADED). This is the default
behaviour for load_image(), so it behaves like R5's implementation now,
i.e. errors while loading are reported to the caller.

* We no longer notify the debugger about a new image when it is registered,
but when it has been relocated.
* When the application image has been relocated, we notify the one who
initiated its loading.

(maybe this should better go into a private header?). If given the function
waits till the loader is done with loading and relocating the executable.
Otherwise it returns before the loader starts.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11690 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added _kern_image_relocated() and _kern_loading_app_failed(), which
are invoked by the loader to provide the kernel with more info.

it actually meant.
* Refactored the image initialization process (init_dependencies()) a bit.
topological_sort() is now more flexible.
* The image relocation is now done by relocate_dependencies(). The order
of relocating the images is the same as the initialization order, so
that the app image is the last to be relocated. After having relocated
an image the kernel is notified.
* The FATAL() macro has another parameter, an error code now, and calls
the new syscall _kern_loading_app_failed() instead of _kern_exit_team().
So the error can be reported to the team that called load_image().

second time for already loaded libraries, when a library/add-on is
loaded.
* image_t features now both, a path and a name. The name is the DT_SONAME,
if present, the leaf name otherwise.
* Modified find_image() to compare both path and name, if necessary.
Added a type mask parameter to specify what image types one is
interested.
* Refactored open_container(). We now also support DT_RPATH, a dependency
search path list that can be specified for the dependencies of a shared
object.
* Extended [un]load_library() to support add-ons.

* When the target is a symlink, it is tried to be resolved before making
the decision what to do.
* If the (resolved) target is a file and the source is a file, we don't
fail anymore, if `-f' wasn't specified. We truncate the target file
instead and copy the source data into it.

Also removed team::user_env_base: environment variables are now changed on the app's heap.

malloc() currently cannot be used in initialize_before() in libroot.so,
and therefore a _after() call has been added for this.

made it thread-safe, although this is not required by POSIX.
Implemented unsetenv(), improved putenv().
