88275138ba kernel/util: Implement more features in the Bitmap class.
* Resize(): adds more space to the end of the bitmap.
 * Shift(): moves all bits in the map up or down.
 * Use size_t instead of int for indexes.

Also add unit tests for the new functions (they seem to be passing.)

Reference material for shift implementation:

9d65dbf1cb boot/efi: rework address-cells and size-cells handling
see Devicetree Specification,
section 2.3.5 #address-cells and #size-cells

The #address-cells and #size-cells properties may be used in any
device node that has children in the devicetree hierarchy and
describes how child device nodes should be addressed.

The #address-cells and #size-cells properties are not inherited from
ancestors in the devicetree. They shall be explicitly defined.

If missing, a client program should assume a default value of 2
for #address-cells, and a value of 1 for #size-cells.

bb09a3ed07 kernel/condition_variable: Remove a confusing requirement for published variables.
Part of the point of published variables is to make them "shareable",
and not require external synchronization. Requiring the callers
to ensure unpublishing does not occur is thus unreasonable, as e.g.
a variable could be unpublished immediately after being notified.

That is the case for some usages of these variables in the FreeBSD
compatibility layer, which under heavy usage, can and did trigger
use-after-unpublishes and then KDLs, at least in local testing.

Instead, only unlock the hash after we have locked the variable.
This is already done in some other functions, so it's safe to do
it here, too. This way, the variable won't be unpublished
while Notify() is running.

02077ffc42 kernel/condition_variable: Atomicize ConditionVariableEntry and drop the lock.
Before 2019, the entire ConditionVariable system was "giant"-locked:
that is, there was a single global lock that all ConditionVariable
and ConditionVariableEntry operations had to pass through. This of
course was not very performant on multicore systems and when
ConditionVariables see significant use, so I reworked it then to have
more granular locking.

Those patches took a number of attempts to get right, as having two
objects in separate threads that can each access the other not turn
into a deadlock or use-after-free is not easy to say the least,
and the ultimate solution I came up with erased most of the performance
gains I initially saw on the first (partially broken) patchsets.

So I have wanted to revisit this and see if there was a better way
even since then. Recently there have been a few reports of
ConditionVariable-related panics (apparently double unlocks),
notably #16894, and so that was reason enough to actually revisit
this code and see if a better solution could be found.

Well, I think I have come up with one: after this commit, Entries
no longer have their own lock, and instead accesses to Entry members
are almost always atomic; and there is now a case where we spin inside
Variable::_NotifyLocked as well as one in Entry::_RemoveFromVariable.

This leads to somewhat simpler code (no more lock/unlock dance in Notify),
though it is significantly more difficult to understand the nuances of it,
so I have left a sizable number of comments explaining the intricacies
of the new logic.

Note: I initially tried 1000 for "tries", but on a few instances I did see
the panic hit, strangely. I don't think the code that is waited on can
be reasonably reduced any further, so I have just increased the limit to
10000 (which is still well below what spinlocks use.) Hopefully this suffices.

Quick benchmark, x86, compiling HaikuDepot and the mime_db in VMware, 2 cores:
before:
real    0m23.627s
user    0m25.152s
sys     0m7.319s

after:
real    0m23.962s
user    0m25.229s
sys     0m7.330s

Though I occasionally I saw sys times as low as 7.171s, so this seems
to be at least not a regression if not a definitive improvement.

The lock entry is the first thing in the struct, so this is a no-op

Spinlocks have been structures for quite a long time, so this was
probably just missed in the conversion.

7aa5574713 kernel & addons: Build with the non-legacy GCC even on x86_gcc2h.
Only one code change: for some reason, GCC chokes on the cr3 functions
as macros (throwing errors about invalid registers.) The BSDs have them
as inline functions instead, so they are converted to that here.

Tested and working. There seems to be about a 10% decrease in CPU time
on some compilation benchmarks that I briefly tried.

7068c45485 system/uart: refactor debug_uart, fix arm uart
* Drop ArchUART8260 layer to reduce complexity. It's whole
  existance in life was to adjust the mmio alignment.
* Fold architecture mmio alignment into DebugUart
* We could potentially pass a Init(int mmioAlignment)
  arg in the future if the macros get too messy.
* Move Barrier code back a layer into DebugUART
* Fixes the arm uart and EFI build

372b901dfe riscv: cleanup architecture macro checks
* We really should get out of the habbit of making up
  our own architecture defines.
* __riscv with an additional  __riscv_xlen is the
  standard that developed... let's just roll with it.

1029af1793 Add missing includes following previous commit.
All these files were making use of headers included indirectly
through AutoLock.h that are now no longer following the previous commit.

057fe1910d kernel: Break thread-related AutoLockers into a separate header.
Including thread.h brings a massive array of things with it from
the kernel thread arch headers, team and thread definitions,
hash tables, linked lists, Referenceable, etc. that the vast majority
of AutoLock.h consumers neither want nor need.

So, put these in a separate header, and adjust all consumers of these
lockers to include the new file.

This change exposes the fact that a lot of files were inadvertently
making use of headers included indirectly through thread.h. Those
will be fixed in the next commit.

0ac46a4ae9 kernel/debug: Adjust range marker macros.
Previously these were just using the raw function name, which led
to markers like "Slab_begin". Now we prefix RANGE_MARKER_ so there
is absolutely no chance of confusion, and the symbols are clearly
visible in dumps.

Also add a note that the kernel must be built with -fno-toplevel-reorder
for these to work. (It seems when this was implemented, GCC had not yet
implemented top-level reordering.)

They are only used for debugging with the tracing system in a handful
of places, and -ftoplevel-reorder is enabled with optimizations for
a reason, so it makes more sense just to note this and not to enable
that option by default (i.e. in the off chance someone will want to
use these in non-debug builds, like I did.)
