df50f7a9b4 * Changed the way the socket functions work:
- The net_stack driver is no longer used. Instead we have a kernel
    module which is directly used by syscall implementations in the
    kernel. I.e. we no longer tunnel those functions through ioctls, but
    have normal syscalls.
  - Removed the superfluous net starter module.
  - Implemented the FDTYPE_SOCKET type file_descriptors, that is sockets
    are no longer vnode based.
  - Adjusted libnetwork (the socket function implementations)
    accordingly.
  - Adjusted netstat accordingly.
* Socket module:
  - Implemented socketpair().
  - Added "kernel" parameter to the control hook. Quite a few more hooks
    would actually need the parameter, but I didn't change those yet,
    since that would probably also require changes to the protocol
    module interface.

25eb8cd717 * Renamed pipefs.cpp to fifo.cpp.
* Removed the pipefs functionality. We only need to support FIFO nodes.
* Renamed the remaining pipefs_*() functions to fifo_*().

6f05787478 * rootfs.c -> rootfs.cpp
* Made the kernel rootfs reusable by the FS Shell and removed the
  copy in the FS Shell sources.

636bfc08ae * Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
  private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
  work pretty much like poll(), but also for semaphores, ports, and
  threads.
* Removed the "ref" parameter from notify_select_events() and the
  select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
  is no longer needed. The FS interface select() hook still has it,
  though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
  pair, now. Added respective functions for semaphores, ports, and
  threads.

66c03dc3a9 * fd.c -> fd.cpp
* Reworked the select support:
  - The io_context additionally stores a table of lists of select_infos,
    which enables it to deselect events of a pending select() when
    closing a FD. This prevents a race condition potentially causing a
    write to stale memory.
  - The opaque selectsync* passed to FSs is now actually a select_info*.
    This was necessary, since the FDs deselect() hook (unlike the
    select() hook) doesn't take a "ref" argument and deselecting a
    single info (e.g. caused by a premature close()) was not possible.
    The select() hook's "ref" argument has become superfluous.
  - It should now be relatively easy to implement a poll_on_steroids()
    that can also wait for objects other than FDs (e.g. semaphores,
    ports, threads etc.). 
* Set/reset the signal mask in common_select(). This makes pselect()
  work as required.
* Reorganized vfs_resize_fd_table().

edb15b5565 bonefish+axeld:
* Simplified the notification framework: removed the updater stuff completely;
  it was only there to account for some peculiarities of the node monitor which
  we now solved differently.
* NotificationListener no longer includes a doubly linked list link for convenience;
  it might want to listen to more than just one service.
* NotificationService cannot have an abstract destructor.
* Changed the _user_stop_watching() syscall to mirror the Be API; ie. it's no
  longer possible to just remove some flags separately, just to stop listening
  completely.
* Adapted the node monitor implementation to live in the NodeMonitorService class
  that uses the new notification framework.
* Removed the public kernel node monitor API - it wasn't useful that way since you
  couldn't do a lot with the KMessage in the kernel without using a private API.
  Now you will have to use the (private) notification manager to use the node monitor
  from inside the kernel. At a later point, we might introduce a public API for that,
  too.

9e8dc2a9bb [Sorry, couldn't split this one up any further.]
* Images preloaded by the boot loader had to be modules to be of any use
  to the kernel. Extended the mechanism so that any images not accepted
  by the module code would later be tried to be added as drivers by the
  devfs. This is a little hacky ATM, since the devfs manages the drivers
  using a hash map keyed by the drivers inode ID, which those drivers
  obviously don't have.
* The devfs emulates read_pages() using read(), if the device driver
  doesn't implement the former (all old-style drivers), thus making it
  possible to BFS, which uses the file cache which in turn requires
  read_pages(), on the device. write_pages() emulation is still missing.
* Replaced the kernel_args::boot_disk structure by a KMessage, which can
  more flexibly be extended and deals more gracefully with
  arbitrarily-size data. The disk_identifier structure still exists,
  though. It is added as message field in cases where needed (non net
  boot). Moved the boot_drive_number field of the bios_ia32 platform
  specific args into the message.
* Made the stage 1 PXE boot loader superfluous. Moved the relevant
  initialization code into the stage 2 loader, which can now be loaded
  directly via PXE.
* The PXE boot loader does now download a boot tgz archive via TFTP. It
  does no longer use the RemoteDisk protocol (it could actually be
  removed from the boot loader). It also parses the DHCP options in the
  DHCPACK packet provided by PXE and extracts the root path to be
  mounted by the kernel.
* Reorganized the boot volume search in the kernel (vfs_boot.cpp) and
  added support for network boot. In this case the net stack is
  initialized and the network interface the boot loader used is brought
  up and configured. Since NBD and RemoteDisk are our only options for
  net boot (and those aren't really configurable dynamically) ATM, the
  the boot device is found automatically by the disk device manager.

Booting via PXE does work to some degree now. The most grievous problem
is that loading certain drivers or kernel modules (or related activity)
causes a reboot (likely a triple fault, though one wonders where our
double fault handler is on vacation). Namely the keyboard and mouse input
server add-ons need to be deactivated as well as the media server.
A smaller problem is the net server, which apparently tries to
(re-)configure the network interface we're using to boot, which
obviously doesn't work out that well. So, if all this stuff is disabled
Haiku does fully boot, when using the RemoteDisk protocol (not being
able to use keyboard or mouse doesn't make this a particular fascinating
experience, though ;-)). I had no luck with NBD -- it seemed to have
protocol problems with the servers I tried.

12d359b85a * Removed write_link from the FS module interface. Adjusted all FS
add-ons accordingly and removed the syscall.
* Removed send_notification().
* Reimplemented notify_listener(). It used the unimplemented
  send_notification(). Now it has a chance to work. Note that
  notify_listener() is obsolete. I would already have removed it, if
  there weren't lots of FS implementations still using it (Hint!).

957a1b17eb * 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.

2db3fced5f Moved vfs_bootstrap_file_systems() and vfs_mount_boot_file_system() out of vfs.cpp
and into its own file vfs_boot.cpp.

Added basic support for booting from CD - it doesn't give CDs a higher priority,
so you could end up booting from HD when you didn't explicetly select "CD-ROM"
in the boot loader. Eventually, it should only boot from HD in this case, if
booting from CD failed (because of a missing boot partition or whatever).

fs_mount(), _kern_mount(), and _user_mount() will now return the dev_t of the
mounted device, and not just B_OK. Maybe we should have fs_unmount() work on
a dev_t instead of a path as well...

718b5114e0 This should fix the build after all the kernel/system renaming.
If anything is still broken (and was not before :)), please shout.
