Add support for both discovery and regular iSCSI sessions. Command and status
sequence numbers do differentiate between session and connection but only
one connection per session is currently supported.
Code is Big Endian for now, so compile it for ppc only.
Based on RFC 3720 ff. Tested against OpenSolaris 2009.06.
Resolves most of ticket #5319.

Modelled after UDP, add limited TCP support to the boot net stack. The socket
works by queuing received packets as well as sent packets that have not yet
been ACK'ed. Some known issues are documented, especially there's only limited
congestion control. I.e., we send immediately and in unlimited quantity, thus
its use should be restricted to local networks, and due to a fixed window size
there is potential for our socket being overrun with data packets before they
are read. Some corner cases like wrapping sequence numbers may cause a timeout.
The TCP implementation is based on Andrew S. Tanenbaum's "Computer Networks",
4th ed., as well as lecture notes from Prof. W. Effelsberg, the relevant RFCs
and Wikipedia. The pseudo-random number Galois LFSR used for the sequence
number was suggested by Endre Varga.
Since the code is unlikely to get much smaller, better merge it now so that
subsequent changes get easier to review. No platform actively uses TCP sockets
yet, and the receiving code has been reviewed for endianness issues and should
terminate okay after verifying the checksum if no sockets are open.
Based on a version tested with custom code (#5240) as well as with iSCSI.
Compile-tested boot_loader_openfirmware, pxehaiku-loader with gcc4 and
haiku_loader with gcc2. Closes ticket #5240.
Changes from #5240 proposed patch:
* Various bug fixes related to queuing, some memory leaks fixed.
* Never bump the sequence number when dequeuing a packet. It's done afterwards.
* Don't bump the sequence number again when resending the queue or ACK'ing.
* Aggressively ACK while waiting for packets.
* Don't queue sent ACK-only packets.
* More trace output, esp. for queue inspection.
* Adapted use of TCP header flags to r38434.

In r33670 the svn:eol-style property was dropped, which took care of
locally converting the line endings to the user's native style.

address ranges, and a set of support functions working with it.
* Changed the type of the kernel_args physical address range arrays to
phys_addr_range and adjusted the code working with those.
* Removed a bunch of duplicated address range code in the PPC's mmu.cpp.

support file creation.
* Extended open() and open_from() to support O_CREAT to create files.
open_from() has got an optional "permissions" parameter for that purpose.
* Fixed errno. It would crash when being used. Also changed the POSIX functions
to return their error code via errno as expected.
* Added writev().
* FAT file system:
- Added support for reading long file names.
- Added support for creating files (8.3 name only) and writing to them.
- Enabled scanning partitions with it.
* Boot loader menu:
- Enabled the "Reboot" menu item unconditionally.
- Added "Save syslog from previous session" menu item to the debug menu.
Currently saving the syslog to FAT32 volumes is supported.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35882 a95241bf-73f2-0310-859d-f6bbb57e9c96
* The kernel syslog ring buffer is no longer emptied by the syslog sender
thread. Instead we only drop the oldest data from the buffer when we're
writing to it and there's not enough free space in it.
Advantages: We drop old data rather than the most recent data when the buffer
is full. The "syslog" KDL command has more data available now. So the odds
are that kernel syslog messages not written to disk yet are at least still
in the kernel buffer.
* Changed dprintf_no_syslog() semantics: Now it writes to the syslog, but
doesn't notify the syslog sender thread.
boot loader:
* Added the ring_buffer implementation and a dummy user_memcpy().
* bios_x86: Moved the syslog stuff from serial.{cpp,h} to debug.{cpp.h}.
* Moved the debug options from the "Select safe mode options" menu to a new
"Select debug options" menu.
* Added option "Enable debug syslog" to the new menu (ATM available on x86
only). It allocates a 1 MB in-memory buffer for the syslog for this session
in such a way that it can be accessed by the boot loader after a reset.
* Added item "Display syslog from previous session" to the new menu, doing
what its name suggests.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35816 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the page table allocation more flexible. Got rid of sMaxVirtualAddress
and added new virtual_end address to the architecture specific kernel args.
* Increased the virtual space we reserve for the kernel to 16 MB. That
should suffice for quite a while. The previous 2 MB were too tight when
building the kernel with debug info.
* mmu_init(): The way we were translating the BIOS' extended memory map to
our physical ranges arrays was broken. Small gaps between usable memory
ranges would be ignored and instead marked allocated. This worked fine for
the boot loader and during the early kernel initialization, but after the
VM has been fully set up it frees all physical ranges that have not been
claimed otherwise. So those ranges could be entered into the free pages
list and would be used later. This could possibly cause all kinds of weird
problems, probably including ACPI issues. Now we add only the actually
usable ranges to our list.
Kernel:
* vm_page_init(): The pages of the ranges between the usable physical memory
ranges are now marked PAGE_STATE_UNUSED, the allocated ranges
PAGE_STATE_WIRED.
* unmap_and_free_physical_pages(): Don't free pages marked as unused.

Remove the 4 cores limit at boot, and fix the allocator to handle 8 cores.
There are still performance problems, but this allows booting with 8 cores.
WARNING: since this changes x86 platform kernel args, you really don't want to update haiku_loader and kernel_x86 separately!

* The vesa driver no longer uses VGA programming if the chip does not support
VGA compatibility.
* The VESA driver now tries to set the DAC to 8 bits per color gun.
* In VESA modes, the driver no longer tries to use VGA programming; introduced
the new vesa_set_indexed_colors() that is now used for palette programming.
This should fix wrong colors of 8 bit BWindowScreen users with VESA on real
hardware (emulators usually didn't mind either way).
* Note that the app_server needs to maintain a palette per 8 bit screen, as
right now, the colors are garbled after a workspace switch. Stefano, are you
looking into that already?

- don't clobber the parameter regs in the entry point,
- fix entry point address for netbsd loader emulation,
- added a gUImage global to point to the uimage blob with the tgz,
- added tgz info to platform stage2 args,
- add simple uimage support, just dumps the header and gets the nth blob in the image, (seems we have a bug in the math code, some infos don't print),
- made devices.cpp use them to publish the MemoryDisk,
- add an haiku_loader_nbsd.ub target which puts both the loader and kernel_arm for now (need to replace with the tgz).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32295 a95241bf-73f2-0310-859d-f6bbb57e9c96
- added some multiboot support code:
- dump some of the passed info,
- parse command line (skip the 'kernel' name and pass the rest to stage2_args.arguments),
- added an add_stage2_driver_settings() function which takes stage2_args.arguments and translates it into safe mode driver settings, a bit dumb for now.
This allows using qemu -kernel haiku_loader -append 'debug_screen true' and get debug output without having to enter the menu (once multiboot info is used to determine the boot device too).
The idea is to allow passing driver settings and using them to pass extra stuff (like 'force_keymap fr' and other stuff for demo), and to help automate tests ('run_test /bin/sometest').
This should answer Axel's question :)

* Adjusted used files systems accordingly.
* BFS::Stream::GetName() was broken. It accessed the small data region
which wasn't loaded, since BFS::Stream derived from bfs_inode, which
is a variably-sized structure with the small data region at the end.
Changed that to a ref-counted, shared member instead.
* Implemented RootFileSystem::GetName().
* Added Directory::GetPath() to get a full path of the directory or an
entry.

* Implement color palette generation for the boot splash images in the
generate_boot_screen build tool. Only 4-bit screen support is missing now.
* Adopted images.h with the new results from generate_boot_screen.
This should fix black boot screens for graphics cards that don't support
true color modes for the native resolution. I've tried to find the ticket,
#2177 almost looks like the one, but it looks more like the mode is out
of range if I understand the ticket right.
Thanks a lot, David, and sorry it took so very long to apply your patch!

* The VESA driver now supports gettings the EDID information as well; this
