libroot: Replace strcspn and strchrnul with musl versions.

Removes the last BSD advertising clause from the "string" directory.

kernel: Move some source files around.

* stack_protector.cpp now lives with other files in "lib".

* Notifications.cpp, wait_for_objects.cpp go to a new "events" directory,
which will soon contain more files related to the event_queue.

No functional change.

libroot: Replace rand() and rand_r() implementations with musl versions.

These functions are obsolete, anyway. We should probably remove
them from the kernel at some point...

BPrivate::WeakReferenceable: Move implementation to a .cpp.

No functional change to the implementation, just getting it
out of a header.

libroot: generate a name for nameless volumes

Generate a name indicating the volume size and filesystem.

Remove code that was doing that or similar things in various
filesystems.

libs/posix: Implemented new locale functions

Implemented the missing POSIX functions in <locale.h>:
newlocale, duplocale, uselocale, and freelocale, and also
provided missing type definitions for <locale.h>.

Implemented missing POSIX locale-based function variants.

Modified LocaleBackend so that it could support thread-local
locales.

Some glibc-like locale-related variables supporting
ctype and printf family of functions have also been updated
to reflect the thread-local variables present in the latest
glibc sources.

As there have been some modifications to global symbols
in libroot, libroot_stubs.c has been regenerated.

23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

Implemented the PPC specific RTC support. We search for an "rtc"
device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

* Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

* Moved realtime_sem.{cpp,h} into new posix subdirectory.
* Renamed the old kernel_posix[_arch...].o to kernel_lib_posix...

* Added real, effective and saved set- user and group IDs to the team
structure. They are properly inherited and updated on
fork(), load_image(), and exec().
* Implemented the get[e]{u,g}id(), set[[r]e]{u,g}id() family for real.
* getgroups() also calls the kernel now, but only returns the effective
group ID. Supplementary groups support is still missing.

Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

Removed gethostname() and sethostname() from the kernel.

Add wait_for_objects.cpp to the kernel, too.

bonefish+axeld: Implemented a robust notification framework for the kernel.
Will be used for node monitoring and other stuff, too (like the Registrar or the
VM low memory handler).

* Added find_directory() to the kernel - it currently may not work as good as the
userland version, tbough.
* Small style cleanup in find_directory.c.

Turn the assembly optimized memcpy (simple rep movsd) back on for x86. Had to hack around the make system a bit, and the result is pretty nasty, specifically due to the amount of places in the system where various targets poke their fingers into the libroot directory.
The solution is less than optimal, but should work for now.

Enabled setjmp()/longjmp() support in the kernel.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@20499 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added strtod() and localeconv() to the kernel.

Moved libroot/posix/kerrno.c to kernel/lib/ where it belongs, and renamed it to kernel_errno.c.

Implemented the PPC specific RTC support. We search for an "rtc"
device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

* Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

* libroot and the runtime loader are no longer built with kernel rules.
* New rule Ld, analogously to KernelLd.
* Added StaticLibrary parameter for supplying additional objects.

Reorganized building of kernel, boot loader, and libroot.
Each component is built in the respective subdirectory now
and no longer in src/system/Jamfile.
