d5e36fb599 * Introduced new fs_lopen_attr_dir() function that opens the attribute
directory of a file without traversing leaf links (just like lstat()).
* Minor cleanup.

36dc99a323 Add private get_memory_properties() syscall which allows one to retrieve the
address protection bits as well as the wiring flags for an arbitrary address
in a team's address space. Will be used in the debugger for the purposes
of the memory inspector/editor, in order to determine whether it can in fact
allow editing for the currently inspected address range.

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.

9c1714ec1a Enable IO-APICs by default. It's been tested on a broad spectrum of hardware and
all reports so far have been positive. We fall back to legacy mode in the cases
where we can't figure out the correct routing.

22a7fe9695 Cleanup system-revision stuff.
* move system_revision.h to headers/private/libroot
* unify libroot's get_system_revision() (the one I introduced recently) with kernel's
  get_haiku_revision(), the function is now called get_haiku_revision() in the kernel
  and __get_haiku_revision() in libroot
* system_revision.c is now being built as part of libroot and as part of the kernel
* adjusted all callers of get_system_revision() accordingly

af2da315dc Fix the larger problem that was hiding behind the build problem of set_haiku_revsion on FreeBSD:
* the length of the sHaikuRevision character array symbol needs to be set explicitly,
  as using either _SYS_NAMELEN or sizeof(utsname::version) will only return the values
  for the host, which may not match ours, thus potentially causing problems when using
  sHaikuRevision
* add headers/private/system_revision.h which defines SYSTEM_REVISION_LENGTH to 128
* adjust definitions of sHaikuRevision in libroot and kernel accordingly
utsname::version is shorter than SYSTEM_REVISION_LENGTH, but that doesn't cause any harm
until we have indeed switched to a DVCS (in which case longer revision strings will be 
cut off by 'uname').

56b5ad0781 Added a temporary opt-in option "enable_ioapic" to the boot menu. This way the
IO-APIC can be easily enabled to test it on various configurations. Note that
the previous default opt-out didn't work because the safemode options would not
be touched at all when not actually entering the boot menu.
Once IO-APIC is more broadly tested this can be removed again and the opt-out
option reenabled.

only a few events can be watched (team creation/deletion/exec, thread creation/
deletion/name changes). The functions start_system_watching()/
stop_system_watching start/stop watching events.

dbe1e23aa8 Optimised passing around of timezone a bit
* _kern_[sg]et_timezone() now accepts/passes out the timezone name, too
* adjust Time preflet and clockconfig to pass the timezone name into the kernel
  when calling _kern_set_timezone()
* ajust implementation of tzset() to fetch the timezone name from the kernel
  via _kern_get_timezone() instead of reading 'libroot_timezone_info'
* the Time preflet no longer writes 'libroot_timezone_info'

7e965f506d More consolidation of timezone code:
* dropped DaylightSavingTime from real_time_clock code in kernel, it was
  never really being used for what it meant (and just being referred to by
  gettimeofday(), which put a different meaning to it
* adjusted the syscalls get_timezone() & set_timezone() as well as their callers 
  accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
  being referred to by the FAT add-on and that one (like gettimeofday()) put a
  different meaning to tz_minuteswest. Added a comment to FAT's util.c
  showing a possible solution, should the hardcoded GMT timezone pose a problem.
* fixed declaration of gettimeofday() to match POSIX base specs, issue 7
* changed implementation of gettimeofday() to not bother trying to fill struct
  timezone - it was using wrong values before, anyway.

96ac47e312 Made some progress with consolidation of timezone-related code:
* renamed syscalls _kern_[gs]et_tzfilename 
  to _kern_[gs]et_real_time_clock_is_gmt, as the filename part is no longer
  relevant (and the two corresponding parameters were removed)
* C++-ified and reworked clockconfig to use the info from 'Time settings' 
  to setup the timezone info during boot
* removed invocation of _kern_get_tzfilename() from tzset(), as the syscall
  no longer exists and tzset() is currently broken anyway
* adjusted the Time preflet to use the renamed syscall when getting/setting 
  the RTC info

of consistency.
* Moved the B_OVERCOMMITTING_AREA flag from B_KERNEL_AREA_FLAGS to
  B_USER_AREA_FLAGS, since we really allow it to be passed from userland.
* Most VM syscalls check the provided protection against B_USER_AREA_FLAGS
  instead of B_USER_PROTECTION, now. This way they allow for
  B_OVERCOMMITTING_AREA as well.
* _user_map_file(), _user_set_memory_protection(): Check the protection like
  the other syscalls do and use fix_protection() instead of doing that
  manually.

813d4cbe94 * Moved created subdirectory src/system/kernel/lock.cpp to new subdirectory
locks.
* Added syscalls for a new kind of mutex. A mutex consists only of an int32 and
  doesn't require any kernel resources. So it's initialization cannot fail
  (it consists only of setting the mutex value to 0). An uncontended lock or
  unlock operation can basically consist of an atomic_*() in userland. The
  syscalls (when the mutex is contended) are a bit more expensive than semaphore
  operations, though.

* When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is
  held longer than DEBUG_LATENCY micro seconds (currently 200). If your system
  doesn't boot anymore, a new safemode setting can disable the panic.
* Besides some problems during boot when the MTRRs are set up, 200 usecs work
  fine here if all debug output is turned off (the output stuff is definitely
  problematic, though I don't have a good idea on how to improve upon it a lot).
* Renamed the formerly BeOS compatible safemode settings to look better; there
  is no need to be compatible there.

  constants cannot be used. The constants are defined using the macros, so now
  there's only one place where the string literals should be specified.
* Use the macros in the partitioning systems. I was too lazy to also adjust the
  file systems -- most of them seem to hard-code the string literal yet.

  function fs_open_attr() that takes a path (same semantics as the
  fs_[f]open_attr_dir() functions already present in BeOS).
* Merged former _kern_open_attr(), and _kern_create_attr() into one syscall.
* Cleaned up vfs.h.
