happen on syscalls or "int" instructions. The debug exception handler sets
the thread debug flags B_THREAD_DEBUG_STOP and
B_THREAD_DEBUG_NOTIFY_SINGLE_STEP (new) and lets the thread continue. Before
leaving the kernel the thread is stopped and a single-step notification is
sent. Fixes#3487.

Work-around for a jam bug with multiple jobs that causes the builtins.o
actions to be executed before builtins.c has been built.

* Renamed DownloadFile to DownloadLocatedFile.
* Pulled a generalized rule DownloadFile out of DownloadOptionalPackage.
* Added InstallSourceArchive rule which can be used in OptionalPackages to
add sources for installed packages to the image.
* Added configure option --include-sources to enable including the sources
for third party software in the image.

notably:
- in hpet_clear_hardware_timer() we cleared the HPET_CONF_TIMER_INT_ENABLE
flag, and never set it back anymore (now we do, in hpet_set_hardware_timer())
- the incorrect interrupt configuration (although it shouldn't matter in legacy mode).
Also test the HPET counter before trying to use it.
Improved debug information.
HPET timers are still at priority 0, since I coulnd't yet test on other
machines (besides mine, QEMU and XenServer 5.5), and doen't work for
some reason with SMP enabled.

mode, revert to the old behavior to include the room for the labels, even if
there aren't any.
Also in layouted mode, trigger a layout invalidation when switching from running
without labels to using labels and vice versa.

* On context switches we do now set the IA32_MSR_SYSENTER_ESP. This saves us
setting esp at the beginning of x86_sysenter(). More importantly when
entering it in single-step mode, this no longer causes a double fault
(cf. #3487). We still don't handle the resulting debug exception correctly,
so that we still get a (continuable) panic().

they were never freed unless the cache was destroyed (I just wondered why
my system would bury >1G in the magazines).
* Made the magazine capacity variable per cache, ie. for larger objects, it's
not a good idea to have 64*CPU buffers lying around in the worst case.
* Furthermore, the create_object_cache_etc()/object_depot_init() now have
arguments for the magazine capacity as well as the maximum number of full
unused magazines.
* By default, you might want to initialize both to zero, as then some hopefully
usable defaults are computed. Otherwise (the only current example is the
vm_page_mapping cache) you can just put in the values you'd want there.
The page mapping cache uses larger values, as its objects are usually
allocated and deleted in larger chunks.
* Beware, though, I couldn't test these changes yet as Qemu didn't like to run
today. I'll test these changes on another machine now.

the terminal size limits defined in TermConst.h. Fixes#3440, although the
main cause -- the incorrect computation of the window size limits -- still
exists.

* Apparently Draw() can be invoked with new view bounds in effect before the
FrameResized() hook has been invoked (I suppose that's not really kosher).
Since TermView updates the terminal dimensions in FrameResized() and relied
on the update rect passed to Draw() to translate to positions within the
limits, an on-stack buffer could overflow, leading to #2851. Now we clamp
the translated positions to terminal size.
* Draw the background areas right of the last column and below the last row
explicitly instead of drawing an additional non-existing partial
character/row.

ReaderLocker::AcquireReader() before starting to wait. This could lead to
busy waiting in loops in certain situations.
* Got rid of the ReaderLocker::AcquireReader(bool) version to avoid confusion.
* Cleaned up and fixed the code introduced in r25408 (VMIN, VTIME support):
- Gave the second ReaderLocker::AcquireReader() parameter the same name as
the corresponding one of WriterLocker::AcquireWriter() and fixed its weird
semantics (one less than the desired number of bytes -- huh?). Since it was
not set on the request, it didn't work correctly anyway.
- tty_input_read(): The O_NONBLOCK return code was broken. It returned B_OK
instead of B_WOULD_BLOCK. The O_NONBLOCK mode overrides VMIN/VTIME now.

* Added command line option '-S', which triggers a new summary mode. When
enabled the image/symbol hits aren't counted for individual threads
anymore, but summed up for all threads. The results are printed at the end.
Works together with all profiling modes (inclusive, exclusive, callgrind).
