24df65921b Merged signals-merge branch into trunk with the following changes:
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
  handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
  support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
  of the real-time signal range. Closes #1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes #6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
  [set]itimer(). Closes #5682.
* Implemented support for thread cancellation. Closes #5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554.
* Lots over smaller more or less related changes.

ea71d6eb4f Made Remove() safe to be called with an element not in the list and changed its
return type to bool to indicate whether it was.

9536ec0297 Reimplemented the gdb stub support for the 'g' command (read registers):
* Added an arch_debug_gdb_get_registers() interface that is supposed to provide
  the register values in the format expected by gdb and implemented it for x86.
* Reimplemented gdb_regreply() to use that. Also made it buffer overflow safe.

8837310ce7 * Slightly alter the semantics of the input gathering function to take the
menu item it's associated with rather than an input string. This allows it
  to calculate the position to start the input at, as well as the correct
  line to place it on. The previous solution always put the input at the
  center line, which happened to be the right place by happy coincidence
  unless one also had the menu items for viewing/saving the debug syslog
  present.
* Implement input buffer scrolling, and consequently lift the previous size
  limit on user input (it is now only limited by the size of the passed in
  buffer).
* Implement parsing of the input buffer to allow it to handle comma-separated
  options. Thus, one can now input things like "disable_smp true, serial_debug_output false"
  and it will be handled properly.

d2b49a0031 * Implement support for user input of additional safe mode options that
aren't otherwise exposed via the safe mode menus. The option can be 
found under the debug options menu, where additional settings can be 
added one at a time with the same syntax used in kernel settings files 
(i.e. disable_acpi on). 

Scrolling of the input buffer is not yet supported (will implement that 
soon), so currently the input is clamped to the size of one line. This 
shouldn't be a problem for our current set of options though.

fb5a1727f4 * Implement interrupt source overrides. We install a relay interrupt handler
at the override entry to trigger the overriden vector so that we don't need
  to configure any additional redirections.
* Also configures the polarity and trigger modes found in the override entry.
* When disabling the legacy PIC, retrieve the enabled interrupts and re-enable
  then in the IO-APIC. This will for example make the ACPI SCI work that is
  installed prior to switching interrupt models. Through the transparent support
  for interrupt source overrides it'll also automatically relay from the old to
  the new vector.

This should make ACPI interrupts work and should support relocating the ISA PIT
from irq 0 to a different global system interrupt (usually 2) so that it can
still work when IO-APICs are in use.

8908aef9c2 * Don't map the IO-APIC within the bootloader. We don't need it to set up SMP
at all and, since there can be multiple IO-APICs, we need to do the
  enumeration again in the kernel anyway. Also only set ioapic_phys the first
  time we encounter an IO-APIC object as it looks cleaner when we arrive at the
  first IO-APIC default address.
* Therefore we don't have to worry about already mapped IO-APICs when
  enumerating them in the kernel.
* Also remove the mapping function that is now not used anymore.
* We still use the ioapic_phys field of the kernel args to determine whether
  there is an IO-APIC at all to avoid needlessly doing the enumeration again.

This fixes multi IO-APIC configurations, because before we would indeed map
the last IO-APIC listed in the MADT, but then in the kernel assumed we mapped
the first one. We'd end up with mapping the last listed IO-APIC twice and the
first IO-APIC never, always programming the last one when we actually targetted
the first one.

a56cbb2afb * When initializing MSI support, don't assume a single 24 entry IO-APIC. Instead
mark the ISA interrupts as unusable and then use ioapic_is_interrupt_available
  to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
  not used, this will simply always return false, leaving all vectors free for
  MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
  done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
  we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external
  routing anymore).

dc14d97b7f * Move the legacy PIC and the IO-APIC code into their own source file. No
functional change intended.
* Use an appropriately sized sLevelTriggeredInterrupts for each controller type.
  This also fixes an out of bound access for IO-APICs with more than 32 entries
  and also returns the right mode in such cases.

67938b0d59 Switched boot splash compression to use boot_zlib (which was already
used by tarfs anyway) instead of RLE.
While this should allows larger logo/icons, it doesn't remove the
current 300000 bytes size limits for haiku_loader, so #6710 is not yet fixed.

4535495d80 Merged the signals branch into trunk, with these changes:
* The team and thread kernel structures have been renamed to Team and Thread
  respectively and moved into the new BKernel namespace.
* Several (kernel add-on) sources have been converted from C to C++ since
  private kernel headers are included that are no longer C compatible.

Changes after merging:
* Fixed gcc 2 build (warnings mainly in the scary firewire bus manager).

0536ff83e9 * IS_KERNEL_ADDRESS(): Avoid the check against KERNEL_BASE or KERNEL_TOP, if
that's the limit of the addr_t domain anyway.
* Defined IS_USER_ADDRESS() to !IS_KERNEL_ADDRESS(), which semantically it was
  already, just more verbosely.

Should, in the future, avoid hundreds of useless Coverity tickets where the
macros are used.

  team_dissociate_data() add/remove data.
* Turned sTeamHash into a BOpenHashTable (necessary since struct team is no
  longer a POD).

c917cd6261 * ARM: Major VM work
- This is mostly a copy of the x86 32bit paging method and infrastructure, this was copied for two reasons:
		1) It is the most complete VM arch
		2) The first ARM PAE patches have landed on alkml, so we will have to deal with it in the future as well,
		   and this infrastructure has proven to be ready ;)
	- No protection features, or dirty/accessed tracking yet
	- Lots of #if 0

	but....

	It boots all the way up to init_modules() now, and then dies because of a lack of (ARM) ELF relocation implementation!

	Since at this point the VM can be fully initialised, I'm going to focus on CPU exceptions next, so we can get KDL to trigger
	when it happens, and I can actually debug from there ;)

userland single-stepping is enabled for the thread.
* x86_exit_user_debug_at_kernel_entry(): Always store DR6 and DR7 in the CPU
  structure, not only when breakpoints are installed.
* x86_handle_debug_exception(): When encountering a syscall single-step, also
  set the THREAD_FLAGS_DEBUG_THREAD thread flag. Otherwise the
  B_THREAD_DEBUG_STOP would be ignored.
* x86 interrupt handling, DISABLE_BREAKPOINTS():
  - Renamed to STOP_USER_DEBUGGING().
  - Now it also call x86_exit_user_debug_at_kernel_entry() when
    THREAD_FLAGS_SINGLE_STEP is set, so that the debug registers are saved.

Fixes #6751.
