39efd913c1 Switch to a 64-bit time_t everywhere except 32-bit x86.
Thus, BeOS compatibility is preserved (and there is no risk of
breaking GCC5<->GCC2 interoperation on hybrid builds.)

This commit only makes the actual change, the build fixes are
in the next commit.

6f7fc2204b NodeMonitor: Added B_WATCH_CHILDREN flag.
* Added a directory argument for notify_{stat/attribute}_changed().
* This allows to watch only a directory, and get the notifications for
  all of its files, not just add/remove entry notifications.

efb0a3a853 EntryCache: Add entry_cache_add_missing() for negative caching.
It provides a way for filesystems to cache a lookup failure and
therefore prevents repeated lookups of missing entries. This is a
common scenario for example in command lookup and compiling, where
each directory in PATH or each include directory is searched for the
given entry.

99086aa323 trim: Target SCSI UNMAP command instead of WRITE SAME.
* The UNMAP command is theoretically much faster, as it can get many block
  ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
  to trim.
* Updated BFS code to collect array ranges to fully support the new
  fs_trim_data possibilities.

077c84eb27 kernel: atomic_*() functions rework
* No need for the atomically changed variables to be declared as
   volatile.
 * Drop support for atomically getting and setting unaligned data.
 * Introduce atomic_get_and_set[64]() which works the same as
   atomic_set[64]() used to. atomic_set[64]() does not return the
   previous value anymore.

map.

4a5a077ff7 Add a private B_ATTR_CHANGE_NOTIFICATION flag to the open query syscall to tell the query to send notifications when an entry attribute changed and the entry stays in the query. Previously you only get created and removed messages, now you can also get updated messages. Only implement it for bfs.
Fix copy right.

d34daac82a * config/{HaikuConfig.h,types.h}:
- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
    (might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
  - Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
    and the types __haiku_phys_[s]addr_t. The intention is to use separate
    macros and types for virtual and physical addresses, since for some
    architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
  - Added types phys_[s]addr_t and respective printf() format macros.
  - Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
    B_HAIKU_PHYSICAL_{32,64}_BIT.

Might break the build under older Haiku installations. Will test next.

(O_MOUNT, O_EXLOCK, and O_SHLOCK). I only left the non-standard O_TEMPORARY
  for the time being (as it shouldn't fool anyone).
* Fixed libutil that already used O_EXLOCK, even though it did not do anything.
* Moved O_NOCACHE, and O_NOFOLLOW to the section with implemented modes.
* Added O_DIRECTORY.

2222d0559d * Introduced new header directory "config", which ATM contains HaikuConfig.h
and types.h. The idea is to provide a basic architecture/compiler
  abstraction by defining types and macros that allow the posix/ and os/
  headers to be mostly architecture/compiler agnostic. 
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
  and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
  types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
  macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
  unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
  defined in C++ mode.

3cf43c2651 Removed the fs_vnode_ops::create_dir() parameter for returning the ID of the
newly created dir. The VFS really doesn't need it and for some file systems
it might not be easy to get by. Several file systems (e.g. rootfs and fat)
were ignoring the parameter anyway.

49004dc730 Remove the additional fs_vnode_ops arugment from get_vnode() again as it's not
needed at all when used as intended. Thanks Ingo for the explanation on how this
is intended to work. Adjusted the overlay fs accordingly and updated/reverted
the changes to the other filesystems.

00405f2286 * Add an additional argument to get_vnode() that gets the fs_vnode_ops of the
node. That is needed for a layered filesystem to be able to construct a full
  fs_vnode out of a volume/inode pair.
* Adapt places where get_vnode is used. Sadly this is a C API and we can't just
  use a default NULL for that argument.
* Introduce a flag B_VNODE_WANTS_OVERLAY_SUB_NODE that can be returned in the
  flags field of a fs get_vnode call. A filesystem can use this flag to indicate
  that it doesn't support the full set of fs features (attributes, write support)
  and it'd like to have unsupported calls emulated by an overlay sub node.
* Add a perliminary overlay filesystem that emulates file attributes using files
  on a filesystem where attributes aren't supported. It does currently only
  support reading attributes/attribute directories though. All other calls are
  just passed through to the super filesystem.
* Adjust places where a HAS_FS_CALL() is taken as a guarantee that the operation
  is supported. For the overlay filesystem we may later return a B_UNSUPPORTED,
  so make sure that in that case proper fallback options are taken.
* Make the iso9660 filesystem request overlay sub nodes. This can be fine tuned
  later to only trigger where there are features on a CD that need emulation
  at all.

If you happened to know the attribute file format and location you could build
an iso with read-only attribute support now. Note that this won't be enough to
get a bootable iso-only image as the query and index support is yet missing.

4612433715 * Added parameter "size_t align" to file_map_translate(). If > 1, the
vector at the end of the file will be aligned to the given value.
* BFS uses an alignment of 512 bytes (should be block size of the
  underlying device or BFS block size, whatever is less), which should
  be fine, since file data are only stored in BFS blocks. This totally
  avoids any partial operations at the I/O scheduler level, thus saving
  disk operations. Not that I could measure any performance difference.
  Theoretically it should help a lot though, particularly when dealing
  with lots of small files, since we avoid using bounce buffers, which
  are (a) limited in number and (b) require copying of the data.

3c1a3047a4 * Added file_cache_is_enabled() function.
* Added file_map_set_mode() function that you can use to keep a whole file
  cached. This is needed for the swap file support: FILE_MAP_CACHE_ALL will
  not only precache all file_io_vecs when called, but it will also cause all
  file_map_translate() calls to fail that would require further caching (ie.
  if the file size had changed).
* Updated the fs_shell file map code to the latest one (with several bug fixes).

7491000f20 Added functions file_cache_{disable,enable}(). They allow to disable
actual caching in the file cache, i.e. all reads and writes go directly
to the underlying device. The implementation is not quite complete,
since the VM can still add pages to the cache when the file is mmap()ed,
which can lead to inconsistencies.

* It now uses S_ISVTX instead of S_ISTXT - this is how it works in Linux as
  well, while FreeBSD uses S_ISTXT there (but S_ISTXT and S_ISVTX have the
  same value there, too).
* Also fixed the fs_shell this time.

7f12cc54a7 * It is now supported that I/O operations and requests are only handled
partially (e.g. due to hitting the end of file). The respective
  classes have grown new methods and attributes to deal with that. The
  "finished" callbacks have got additional parameters to indicate
  whether the transfer was only partial and how much has been
  transferred. Other callbacks and functions have a size_t* in/out
  parameter instead of a simple size_t, now.
* vfs_{read,write}_pages() do now use the I/O request framework instead
  of the underlying FS's {read,write}_pages() hooks (those should be
  unused now). Furthermore they've got an additional "flags" parameter,
  which is passed to IORequest::Init(), i.e. it allows to specify that
  the given vecs refer to physical addresses.
* The file cache's read_into_cache() reads directly into physical
  pages, now.
* Fixed bug in DoIO::IO(): The offset was not adjusted, so that all
  pages were incorrectly transferred from/to the same location.
* Fixed broken subrequest scheduling loop head in
  do_iterative_fd_io_iterate().
* Adjusted the test driver and implemented its io() hook. Using this
  driver I/O requests are passed all the way from the VFS/VM to the
  driver and through the I/O scheduler. It even seems to work. :-)
* Added missing const to the iovec* parameter of the IORequest::Init()
  methods.
* Disabled some debug output by default. Added new optional debug
  output.

37de5a0d83 * The rw_lock now behaves just like a recursive locker if KDEBUG_RW_LOCK_DEBUG
is defined to 1; this allows asserting the read lock case, too.

  working when KDEBUG_RW_LOCK_DEBUG is defined to 1, the write assertion works
  always.

ec598fe493 * Added FS interface hooks io() and cancel_io(). The former is supposed
to provide asynchrounous (or only synchronous, if asynchronous is not
  supported) I/O request support. It will eventually replace
  {read,write}_pages(). None of the FS implementations implement them
  yet.
* Implemented some support functions for request-based I/O. File system
  implementations can use do_fd_io() which passes an I/O request to the
  layer responsible for a given FD, and do_iterative_fd_io(), which
  translates a request for a file to subrequests for the underlying
  device and passes them on. Both fall back to synchrounous processing
  when the io() hook is not supported.
  Furthermore added vfs_synchronous_io() which should be handy for the
