f1fafe317f kernel/OS.h: Include sys/types.h instead of pthread.h.
This avoids polluting the namespace significantly. Also adjust
all files which depended on this behavior to include pthread.h
directly.

5ffbe7d778 Change all references to "__INTEL__" to "__i386__".
They are functionally identical, but the former is a BeOS/Haiku-specfic
macro that we include in the compiler specs, and the latter is defined
by GCC.

5629675a32 sparc: add defines and minimum set of required files
Gets the stage0 bootstrap to run.
Imlementation is probably nonsense at this point.

c5e4e4ffb4 headers/kernel: Include declarations of initialization functions in image.h.
No "real" functional change, but this causes GCC7 to throw errors when
these functions are declared without the image_id argument, which
in some files they were (as this commit repairs.)

This change is largely inconsequential on x86, but on callee-cleanup-args
targets, leaving out the argument would probably cause stack corruption.

d545ad17ce headers/kernel: Define B_CURRENT_IMAGE_SYMBOL via __func__.
Previously, __haiku_init_before was a symbol that was included in
each (shared) object, and so it could be used to determine what
one we were in. Now, there are no such universal symbols that
are declared private to only the object, so we have to use
a different approach.

__func__ is defined as a const char* at the very beginning of
every function it's used in, set to a string of the function name
only, i.e., the arguments and return type are left off. So while
including that is perhaps not quite optimal, in practice this
definition is used extremely rarely (it was introduced by Haiku,
and it is used in only 2 applications at all that I could find --
WebKit and Canna.)

There really isn't any other way to get a pointer that we know
for certain is within the current object besides this one
without inserting one, but that really isn't merited just for this.
(__builtin_return_address() has problematic semantics wrt. inlining,
including linker-inlining.) So this will have to do.

475172337b headers/kernel: Move B_WAIT_TILL_LOADED to a syscall header.
It is only used as an argument to _kern_load_image directly, not to
any of the load_image functions in image.h, so it belongs in a syscall-
specific header like other such constants.

No functional change intended.

ef593f61a2 ELF: Ignore PT_EH_FRAME and PT_STACK.
This allows Clang builds (linked with our cross binutils) to
at least start runtime_loader and then try to load launch_daemon.
That fails with an infinite loop somewhere...

fb4cc98472 build: Add initial ARM64 target.
It will probably be just stubs for the significant future, but,
here it is anyway.

Regarding the naming: Yes, the official name is "aarch64." However,
Linux, FreeBSD, and Zircon all call it "arm64", and so we will do the same.

I've configured it initially to be a Clang-only port, making no
changes to GCC buildtools whatsoever here. We'll see if that sticks,
however.

9a50e01ea6 set_real_time_clock: Change parameter from uint32 to uint64.
This should have been done along with the time_t change, but I forgot
to check this then.

Technically this breaks ABI against BeOS, but:
  1. BeOS used an int32, so we'd already slightly broken ABI here
  2. Only one thing at HaikuArchives (VMwareAddons) and one recipe at HaikuPorts
     (samba) uses this function at all.

If it turns out some critical BeOS app uses this, then I guess we can enclose
GCC2 guards around it, but since I can't find any evidence of that, I'm
pushing it without them for now.

467fe4ca0c kernel: Add core dump facility
* Add function core_dump_write_core_file(). It writes a core file for
  the current thread's team. The file format is similar to that of
  other OSs (i.e. ELF with PT_LOAD segments and a PT_NOTE segment), but
  most of the notes are Haiku specific (infos for team, areas, images,
  threads). More data will probably need to be added.
* Add team flag TEAM_FLAG_DUMP_CORE, thread flag
  THREAD_FLAGS_TRAP_FOR_CORE_DUMP, and Team property coreDumpCondition,
  a condition variable available while a core dump is progress. A
  thread that finds its flag THREAD_FLAGS_TRAP_FOR_CORE_DUMP set before
  exiting the kernel to userland calls core_dump_trap_thread(), which
  blocks on the condition variable until the core dump has finished. We
  need the team's threads to stop so we can get their CPU state (and
  have a generally unchanging team state while writing the core file).
* Add user debugger message B_DEBUG_WRITE_CORE_FILE. It causes
  core_dump_write_core_file() to be called for the team.
* Dumping core as an immediate effect of a terminal signal has not been
  implemented yet, but that should be fairly straight forward.

81e04d7b97 kernel: Remove cpu_info::load
This field forces kernel to track each CPU load all the time. It is not
a problem with the current scheduler on a multicore systems, but on
single core machnies or with any other future scheduler this field may
become just an unnecessary burden. It isn't difficult for an application
to compute CPU load by itself when it needs it.

77ea49f4f2 Adjust debug API to address some x86-64 concerns.
- The argument buffer contained in the debug_{pre,post}_syscall message structures wasn't large enough to accomodate all
arguments for some syscalls on x86-64, which could potentially have led to kernel memory corruption when using syscall
tracing via the debug API. As such, enlarge it to accomodate 64-bit platforms as well.

- Adjust TeamDebugger/SyscallInfo to discriminate the target architecture and read the arguments when trapping console
output. Gets the latter working on x86-64.

5d0a1da8bf libroot: make all areas executable for old binaries
* If at least one image is either B_HAIKU_ABI_GCC_2_ANCIENT or
   B_HAIKU_ABI_GCC_2_BEOS almost all areas are marked as executable.
 * B_EXECUTE_AREA and B_STACK_AREA are made public. The former is enforced since
   the introduction of DEP and apps need it to correctly set area protection.
   The latter is currently needed only to recognize stack areas and fix their
   protection in compatibility mode, but may also be useful if an app wants
   to use sigaltstack from POSIX API.

65ed4fa908 vm: implement B_RANDOMIZED_IMAGE_ADDRESS address specification

b3e4c67739 vm: implement B_RANDOMIZED_ANY_ADDRESS address specification
Randomized equivalent of B_ANY_ADDRESS. When a free space is found (as in
B_ANY_ADDRESS) the base adress is then randomized using _RandomizeAddress

f9bab525f6 vm: implement B_RANDOMIZED_BASE_ADDRESS address specification
B_RAND_BASE_ADDRESS is basically B_BASE_ADDRESS with non-deterministic created
area's base address.

Initial start address is randomized and then the algorithm looks for a large
enough free space in the interval [randomized start, end]. If it fails then
the search is repeated in the interval [original start, randomized start]. In
case it also fails the algorithm falls back to B_ANY_ADDRESS
(B_RANDOMIZED_ANY_ADDRESS when it is implemented) just like B_BASE_ADDRESS does.

Randomization range is limited by kMaxRandomize and kMaxInitialRandomize.
