The video buffer used for colorspace conversion was not aligned enough
(it could need as much as 64 bytes alignment) and did not include enough
padding (the functions work on 64 bytes blocks at once in some cases).
This code could be made simpler by using sws_scale_frame instead of

The BIOS module is used to run BIOS code in a "fake" machine so it can
be called from protected mode without having to go back to real mode.
To achieve this, it copies some parts of the physical memory into that
physical machine. It used to also map some of that memory directly
rather than copying it.
In hrev55544 this was changed to do a copy instead of a mapping. The
copy can then be written to, which opens the way for VESA BIOS live
patching.
However, the copy also means that the entire copied physical memory area
is accessed by the CPU. That area includes the VGA memory, which may not
exist or be masked. In particular this happens in QEMU by default (the
memory is only mapped when graphics mode is activated). In the case of
the NVMM virtualizer, this results in a crash of the virtualizer as
the guest attempts to access memory that doesn't exist.
To avoid the issue, the "fake" machine now includes a copy of the EBDA
(top of RAM) and the BIOS ROMs, but not the video RAM (that part of the
memory space is left uninitialized). This way, it doesn't matter if the
hardware has valid memory there or not.
With this fix, Haiku can boot even without the "Don't call the BIOS"
option set.
Thanks to sed4906 and waddlesplash for the help in locating the issue!

Tracker creates a drag bitmap containing the selection being dragged.
There is a size limit if the selection is too large to avoid moving a
huge bitmap around.
There were two problems with the way this was done:
- The smaller rectangle was always centered on the cursor, even if that
was near the edge of the selection being dragged. In that situation,
most of the drag bitmap would end up being empty. Instead, move the
rectangle to align it with the edges of the selection if it goes
outside them. This makes sure we always use as much of the drag
rectangle as possible for useful data.
- Moreover, there was a regression on the rendering of the
"fade" at the edge of the rectangle. This is a transparency gradient
that should be at the edge only, to indicate that the drag bitmap has
been truncated, and that more (invisible) things are also being
dragged. In hrev58665, this transparency gradient was changed to cover
the entire width and height of the dragged bitmap, instead of just the
edge. This lead to most of the text being almost invisible in a lot of
cases. Change the code to use a gradient only near edges again.

TFilePanel inherits from Tracker's ContainerWindow, which calls Run() in
its constructor.
This results in the constructor of the subclasses being run while the
window message loop is already running and processing messages.
Specifically, views are getting resized and moved both by the
constructor (in RestoreState) and by the resizing code (_ResizeBy
recursively relayouting all children).
This results in the cancel button being left at the wrong place at the
end of the constructor (or shortly thereafter). While that on its own
has no consequences because the layout is fixed when the window is
finally shown, the position of the cancel button just after the
constructor is relied on by applications which add custom widgets to the
window (Wonderbrush, Icon-O-Matic, Pe for example).
Make sure to keep the window locked while setting it up, so the message
loop does not interfere.

Timestamps in BFS are stored with a 16 bit subsecond precision. However,
a lot of files have this field set to 0 as they are created with APIs
that do not set a subsecond precsion value.
The previous format (introduced in hrev31057) did not track wether the
stored data was a 12 bit sequential number or a 12 bit subsecond
timestamp + 4 bit sequential number.
As a result, setting a timestamp with nsec=0 would read back a different
value (exposing the sequential counter to userspace).
Older versions of Haiku, and BeOS according to the Practical Filesystem
Design book, did not store a timestamp there. Haiku used to store the
volume UID (I don't understand why), and BeOS stored a sequence number
because the POSIX APIs at the time didn't allow to get and set the time
with nanosecond precision.
The Practical Filesystem Design already mentions that storing a
subsecond precision value here would have been better than their
workaround.
The new format relies on the fact that nanoseconds can only be in the
range from 0 to 999999999. After the conversion to a 16 bit value using
simple shifts, this result in a maximum possible value of 0xEE60. The
new format exploits that, and uses the range 0xF000 to 0xFFFF to
represent 0 timestamps with a 12 bit sequence number.
This allows the sequence number to be hidden from userspace entirely.
Fixes#19213.

endpoint and the connexion is stuck (it appears sending data still
works, at least from the network stack point of view).

- Update the file with the latest version (from
https://uefi.org/sites/default/files/resources/devids%20%285%29.txt)
- Tweak the Jamfile and awk script a bit to fix conflicts with acpi
device IDs structures, add missing const, allow tabs in the input file
instead of spaces (it is not formatted consistently)
- Match the hid or cid of ACPI devices to show well known names from the
file if available and we have nothing better.

Add the following:
- CS and SS registers
- For 32bit: DS, ES, FS, GS registers (on 64 bit these are not part of
the iframe structure)
- CR2 register (fault address)
- Hardware interrupt number
- Hardware error code
The hardware error code, interrupt number and fault address are not
modifiable by the signal handlers. The other registers can be modified.
This is used for example in dosemu to intercept errors from JIT generated
code and resume execution. Wine can also make use of it.
In order to not change the size of struct mcontext, these are inserted
in a region of the FXSAVE structure that is available for the OS to
store some data (as documented by Intel) and that we didn't use before.
Fixes#7867

Just the library name in parentheses doesn't look so great in the book
index (in particular for libroot in the "special topics" list). So include
a short description there.

The RTLD_GROUP flag to dlopen comes from Solaris. It makes the symbol
resolution for dlopen not use the global symbols from the current team
(anything that's already loaded). The loaded object must be explicitly
linked against any symbol it needs to use (or it can use dlsym to search
symbols in the global scope explicitly).
This is also how symbol resolution worked in BeOS, meaning we already
have the code to do this, and just need to enable it.
This can be used in dosemu, where DOS-like executable are linked against
their own C library and should not use symbols from libroot.
Fixes#19674.

The openboot mmu code does not like addresses above 4GB, so load the
kernel to a lower address. It doesn't really matter anyway, because on
sparc the kernel normally lives in a separate address space and uses
special instructions to access userland memory.
See #19597 for details, further changes will be needed here.

The old BUrl constructor with just a string is now private. The new one
has a default value for the second parameter, but C++ doesn't exclude
the private constructor from the candidate functions search. So, the
default argument for the new constructor needs to be explicitly
specified now.

This is unused but defined in Darwin, BSD, and Linux.
It allows developers to feel good about specifying that they want to map
a file (which is the default behavior anyway). The value is 0, so
specifying this flag does not have any effect.
This allows to more easily compile code that uses the flag.
