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.

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.

x86_64 already does this and it seems to work fine. Since stack areas
grow downwards and should always have a guard page, overruns shouldn't
be too much of a concern (for that matter, randomization still makes
a difference here also, it seems.)
This allows us to regain another ~256 MB or so of contiguous address

0x7.. block, but if you had 10MB of free address space below 0x6..,

To allow consumers to cause the "don't fragment" bit to be set in
all IPv4 packet headers.
There is no standard way of doing this, and different OSes expose
this option in different ways. Linux has "IP_MTU_DISCOVER", but it
takes an enum, not a boolean. NetBSD and OpenBSD appear to have
no socket option, instead they have "IP_MTUDISC", an option for
the "ip_output()" kernel-level network stack method.
"IP_DONTFRAG" sockopt originates on FreeBSD, and it seems macOS now
also supports it in version 11+. Windows has "IP_DONTFRAGMENT",
which, at a glance, appears to do the same thing. So this looks
like the one that makes the most sense to adopt.
This doesn't add any code to process MTU changes yet, though.

Deprecate the UrlEncode member function and make it private. Instead aadd a new
way to handle URL encoding:
- All ways to set an URL (constructors, SetUrlString, and all setters)
now take an extra boolean parameter indicating if the string is already
encoded. The default value is to encode strings automatically.
- The static version of UrlEncode and UrlDecode, which operate on a
string, are preserved and used by other parts of the API.
All unit tests adjusted to handle this, and still passing.

* Introduce notify_query_entry_moved to the fs_interface API.
axeld added a hook to the query parser (then in BFS) in hrev34317
to directly handle moves/renames, but just sent notifications for
it as B_ENTRY_REMOVED + B_ENTRY_CREATED (which is in fact the same
exact thing BeOS R5 did, I tested). We need to preserve that ABI/API,
unless flags that didn't exist on BeOS R5 are set.
* Rework notify_query_attr_changed to notify_query_attribute_changed.
This method is Haiku-specific (it was added in hrev39131), but it
wasn't very useful: it only sent the name of the file, not the name
of the attribute that changed.
It now sends the name of the attribute along with an "int32 cause",
same as notify_attribute_changed does.
* Rename the private flag B_ATTR_CHANGE_NOTIFICATION to B_QUERY_WATCH_ALL.
This better describes what it does (it's analogous to the B_WATCH_ALL
node_monitor flag). Probably we should make it public at some point...
(although probably at a lower value.)
* Overhaul QueryParser notifications logic to implement WATCH_ALL
properly, make use of the new and improved notification methods,
and to deduplify some logic.
This makes it possible to use queries with B_QUERY_WATCH_ALL
in a similar fashion to watching a directory node with B_WATCH_CHILDREN,
avoiding the need to watch every single node individually.
This way, they are available by default when not using a strict
language standard version.
The change is applied to all architectures (except m68k, which doesn't
define them at all).

We can't rely on it not changing between calls, especially as
MaxUpdateTextWidth() changes the value and re-gets it, and
that's called at the end of this method always. So we need to
keep our own copy rather than using the one that's owned by
the subclass.
Fixes a use-after-free uncovered by the guarded heap in VolumeSlider,
reported in #19493.
It accesses values through macros, so just write functions that
fetch the appropriate value from Haiku's structures.
Note that the values for multibyte digit characters are hardcoded.
As far as I can tell, we never set or updated these in glibc's
locale structures, so it always just used the default, so this
should not be a behavioral change from before.
Otherwise it needs to use libio internals to implement these,
which we don't want. musl also exports all these methods for
the same reason.
Implementations taken from glibc 2.15, current gnulib (5077f67), and
in a few cases tweaked for better Haiku support.
Should fix#19479.
* Take it from upstream glibc 2.15, much closer to the version we use.
* Drop fpurge from stdio.h, it's nonstandard. Keep it around for
ABI compatibility for now (BeOS didn't have it.) __fpurge is left
in stdio_ext.h.
See inline comment: otherwise we could deadlock waiting for busy pages.
At the same time, make page_faults_allowed just an int16 and drop
atomics and extra checks, they aren't needed.

it seems they didn't themselves depend on any of the definitions it
