56d734a1aa Added new private API to get more information on a team:
* Userland interface: get_extended_team_info().
* Syscall: _kern_get_extended_team_info.

Only partially implemented yet.

de2e54ace0 Adjust tzset() implementation to better follow the POSIX specs and
make some more perl tests happy.
* no longer expect a ICU timezone ID in the TZ environment variable,
  but only expect this format if the TZ-value is starting with ':'
* accept "standard" TZ-values like "EST5" (of which only "EST" is
  relevant to us) - if such a value is specified, we hardcode the
  timezone name to the given value, no matter how ICU calls it
* adjust tests accordingly

bd13a264f7 Fix :
* remove declaration of ctype-..._l() functions, as we do not provide
  them and they are not really needed by our hacked glibc
* replace remaining invocations of isspace_l() and isupper_l() in glibc
  with isspace() and isupper() respectively
This allows libroot to be built in DEBUG mode, again.

85f9496a24 Implemented __cxa_atexit() and __cxa_finalize() which are required by the
Itanium ABI. Whether __cxa_atexit() really works for associating hooks with
DSOs has not been tested yet, as our compiler doesn't use the function.

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'

* added respective tests to locale_test
* added two more tests copied from glibc, test_time.c and tst-mktime.c

5091a866ec To be validated as part of bug . Update glibc regex to 2.11, headers/posix/regex.h included. This imposes some changes in some of our sources using the regex.h,
mostly bin tools and mail kit. The use of __USE_GNU macro is needed for instance when the expected regex implementation is the GNU one.

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

bca50be432 Second go at fixing what should have been part of r31927:
* uncommented fwscanf() in wchar.h to make it available
* imported wcsftime() from FreeBSD-8 (which just wraps strftime()), so that we 
  not only declare it, but provide an implementation, too
As a result, the next build of gcc4 should be able to detect full support for wchar_t and in turn activate wchar_t-based template types (like std::wstring).

f71274580b * Private libroot locking primitives:
- Reimplemented mutex to use the _kern_mutex*() syscalls.
  - The initializer functions cannot fail anymore -- changed their return type
    to void.
  - Changed the initializer function semantics to not copy the name by default
    anymore (as in the kernel). Also added *_etc() versions of them that take an
    additional flags.
  - Added static initializer macros.
  - Made the mutex (and thus recursive_lock) lock functions non-interruptable.
  - Got rid of the "lazy" version. They are no longer needed, since the
    initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
  locking primitives to the new semantics.
* pthreads mutexes and condition variables:
  - Reimplemented using the _kern_mutex*() syscalls.
  - Consistently use POSIX error codes.
  - Fixed some not quite POSIX compliant behavior.

081ff2db28 * Add heap_debug_set_memory_reuse() which allows to disable memory reuse,
keeping all returned heap memory in the 0xdeadbeef state (including the
  first sizeof(void *) bytes otherwise for the free list). While wasting a lot
  of memory it allows you to rely on 0xdeadbeef being always present as no
  future allocation will reuse the freed memory block.
* Also added heap_debug_malloc_with_guard_page() which is intended to allocate
  a memory block so it is aligned that the start of invalid memory past the
  allocation is in an unmapped guard page. However the kernel backend that would
  guarantee this is not yet implemented, so right now this works only by chance
  if no other area happens to be allocated exactly past the created one. With a
  very specifc suspicion you can put that one allocation you get to good use
  though. It causes a crash when accessing memory past the allocation size so
  you actually get a backtrace from where the access happened instead of only
  after freeing/wall checking.

638a24fa52 * Seperate the raw page wise allocation and allocations from bins.
* Make the contiguous page allocation capable of aligning the allocation
  and make it more clever by checking up front if there's a chance of getting
  enough pages at all, by giving up earlier if the page count can't be fit
  anymore, and in the alignment case by only checking the pages which have a
  valid alignment.
* If the alignment requirement is > B_PAGE_SIZE we now use page allocation
  directly, because the bins aren't necesarily aligned on their size past
  B_PAGE_SIZE anymore.
* When doing aligned bin allocation, calculate the aligned size up front and
  choose the right heap for the allocation.
* Also when doing aligned bin allocations we not only need to round up the size
  but also ensure that the bin we choose is aligned at all.
* Moved adding leak check info into it's own function.

Fixes various misalignment problems when working with alignments > B_PAGE_SIZE
or when using alignments < allocation size. Also the directly aligned page
allocations now only use up as many pages as actually required instead of
allocating based on the rounded up to align size.

0ccd0a0b6f axeld+stippi:
When initializing driver settings, make sure to set the parameter count to 0,
because these settings have not been parsed yet. This allows us to safely free
the settings. Freeing the settings is triggered in load_driver_settings() if
we encounter settings which have been originally loaded by the boot_loader,
which might be stale. I think the bug would trigger for settings which had been
loaded by the boot_loader but had never been parsed.

With this change, I can use the userlandfs on all my machines.

 * FSUtils no longer creates /home/Desktop on every volume.
 * TrashWatcher now keeps icons in sync on all volumes.
 * Simplified FSGetDeskDir since it no longer has to worry about getting the desk directory on any volume other than the root.
 * Relocated trash context menu logic to BContainerWindow so it can also be used at the volume roots.
 * DesktopPoseView now creates a virtual Trash pose representing the trash contents as before.
 * Corrected typo: Model::WriteAttrKillForegin() -> Model::WriteAttrKillForeign().

90daf7c61e * init_after_fork(): In case the reservation for the heap area failed
sHeapBase will probably not point to memory in the heap area. Use
  sFreeHeapBase instead.
* When reserving the heap area range fails, set sHeapBase to NULL, so we'll
  later know about the fact.
* hoardSbrk(): When resizing the area fails, we'll now try to allocate a new
  one, if the former failure was not due to an "out of memory" situation.
  E.g. if the heap range reservation failed or, if we just have exhausted the
  range, another area could be in the way. Also when mmap()ing over
  malloc()ed, the heap area count be split in two with the first part
  retaining the old area ID, thus preventing resizing as well. Fixed .
