Fixes#6423 and helps with #14626.
In BringUpInterfaces, line 772 creates an error which only adds a missing
interface if one does not already exist (i.e., !_testInterface()). This can lead to
a missing WiFi interface if an Ethernet connection has been configured and set in
the /boot/system/settings/network/interfaces before the WiFi has had a chance to
be added to /dev/net. To properly configure a missing device, such as a WiFi
connection, and allow the user to choose amongst configured interfaces (i.e.,
add it to the list of devices in /dev/net and e.g., see WiFi as an option),
removing the 'if' statement on line 772 is necessary.
Two edge cases may arise:
1. A user may disable an interface -- don't add device
Solution: The code currently handles this. _ConfigureInterfacesFromSettings, called
at line 746, checks for interfaces in fSettings to see if they are disabled (706-711).
If so, they are disabled and not set as a missingDevice if the interface is disabled
(709). The next interface is checked... etc.
2. Devices must not be added twice (i.e., Checking for An Existing configured Network)
Solution: The code currently checks for this. On lines 716-720, a device that is found
in fSettings (missingDevice), is set to the interface which is later added to the
/dev/net within that (unnecessary?) if statement (772). The missingDevice will only
be set and added to /dev/net if an entry does not exist in the settings already (716)
(hence the identifier missingDevice).

This change is a reshuffle of the backend processing involved in the
aquisition of data from servers including the pull-down and load of
HPKR data as well as the pull-down and load of data from the
HaikuDepotServer (HDS) system. The driver for this change is to
implement an initial implementation of a progress bar for the
loading of data as the application starts.
The following are notable changes;
* Removed some previously attempted 'functional style' logic in the
model which didn't fit well with C++
* Use of the base-url in the logical mapping from HDS and HD data is no
longer required and has been removed
* Some logging has been improved making it clearer which part of HD
is producing the logging which in turn helps with debugging issues
* List class has been modified to more cleanly support sorted lists
and binary searches; tests have also be updated accordingly
* Reorganise and tidy-up of the data-loading processes' structures
* The local repository update (HPKR) and data-load occur in background
processes now in the same system as the HDS data-load - this has been
crudely shifted from the MainWindow to new Processes and incorporated
into the background processing system
* The 'state-machine' background process runner is now replaced with a
'coordinator' style approach that can more easily handle the new
processes related to HPKR loading.
* Progress for loading processes is shown in the main window in the
WorkStatusView - this is flickering a bit, but basically works
* Added some documentation regarding how Processes work in the system
* The "Refresh Repositories" menu item now also updates data from HDS
* The "Refresh Repositories" menu item is disabled when the background
processes are running that update the repository data
Some further refinement would be good, but this change is large enough
for one round of improvements. There is an issue that the status bar
is used for screenshot display as well as this data-loading, but that
was the case before so it is something that can be dealt with later if
it is a problem.

One minor change from owenca's original patch: we can't return
immediately if urlString is NULL, as the caller probably wants
the urlLength.
* Fixes crashes when the DTV is concurrently resized by multiple threads.
* Fixes JVM crash or endless loop when building OpenJDK.
* Should help with #13154, #14129, #14304, #14342.

SetTo frees the buffer before setting it to the new one,
but if KPath sets itself to ... itself, then it will of course
try to access the buffer again.
Spotted by clang-analyzer (amidst quite a few false positives,
so this doesn't seem like an especially good rabbit hole
to go down right now.)
When double-clicking a result in TextSearch, it opens the file with
the preferred application for that file type. In case you search
through e.g. a HTML file, that would be most probably WebPositive,
which is not what you want normally.
TextSearch has the setting "Open files in Pe" which forces all files
to be opened in the Pe editor.
With this change, it will force the files to be opened in the
preferred app for text/x-source-code.

When the FD is put() but not freed while O_DISCONNECTED, its "ops"
and "vnode" are cleared. Thus it is entirely valid for a non-NULL
file FD to have a NULL vnode, so we should just treat such FDs
as if the locks had already been cleared (which they should have.)
Fixes#14294.
Since these do not go through get_fd, which would check for them,
we need to do these checks manually in the relevant locations.
Some of these changes were broken out from axeld's original commit,
and some were found by my own auditing.
axeld's solution from 2015 worked in that it solved the panics and
problems with leaking FDs ... but only if nobody actually tried to
use the FDs again. As you can see in the diff of the previous commit,
in allowing closed FDs (which have NULL "ops") to be returned by get_fd,
all consumers of the get_fd API (so, pretty much most functions in
vfs.cpp and fd.cpp) have to check *both* that (1) the fd is not NULL,
and (2) the fd does not have O_DISCONNECT set.
Besides missing a large majority of consumers of get_fd (which caused
ticket #14532 and also the first half of ticket #14756, probably among
others, as I haven't reviewed all NULL-dereference-in-VFS tickets yet)
this solution missed the fact that calling get_fd increments the reference
count, but then exiting the exact same way as if the FD was NULL
(without putting it) when it is disconnected *also* leaks the FD.
As it turns out, a not insignificant number of applications try
to do this, which (depending on whether you went through one of the
'lucky' functions axeld's commit touched) either (1) leaked the FD,
or (2) caused a kernel panic.
Now, we could go through and add O_DISCONNECT checks to every single
consumer of get_fd followed by put_fd to get the proper behavior ...
but that would be the same thing as just returning NULL here and not
incrementing the reference count.
So it seems the first part of axeld's solution (don't set open_count
or ref_count to -1 but leave them as-is) is the only change necessary.
A few places where there were legitimately missing O_DISCONNECT checks
(some originally added by axeld) are (re-)added in the next commit.
Otherwise this seems to be the more robust solution. (But I wonder why
nobody caught this in the code review axeld asked for in the commit
and the ticket back in 2015? Did nobody notice the unbalanced get/put?)
Fixes#14532, part of #14756, and probably any other NULL dereferences
in VFS I/O functions (XHCI is especially good at exposing these)
that are lingering around on the bugtracker.
* Added subsampling. This makes the render look less noisy and generally nicer.

As axeld pointed out on the mailing list, map_backing_store is called
with the address space write-locked, and so the resources won't be
released until after we return.
Due to the state we are in at this point, unlocking the address space
before making this call would be likely be very dangerous, and so
simply issuing the notification and then returning an error is all
we can safely do here.
Fix using local variable within a loop with a same name
as a variable controlling this loop.

The altcodepatch mechanism needs to overwrite parts of the kernel
image. This can't be done by setting it to RW-only and not RWX,
as we are already running within the kernel when this occurs,
and so instruction fetches can and will occur between the points
of +W and -W.
As gKernelStartup is turned off before the scheduler is started,
this is not much of a lifted restriction, as no modules are loaded,
no secondary threads started, etc.
Fixes#14751.
This file is included, directly or indirectly, by most of the
kernel-space C++ code, and so importing the entirety of "std"
seriously pollutes the global namespace.
So instead, just import "std::nothrow", which is the only thing
we really want in the global namespace. Tested on both GCC2
and GCC7 and seems to work just fine.
While I'm here, also update the include guards and copyright
header to match the standard format used elsewhere.
