Currently the failure code path doesn't do any kind of cleanup against
the hive that was being linked to master. The cleanup is pretty
straightforward as you just simply close the hive file handles and free
the registry kernel structures.

Log debug output of the lazy flusher as much information as possible so that we can examine how does the lazy flusher behave, since it didn't work for almost a decade. Verbose debugging will be disabled once we're confident enough the registry implementation in ReactOS is rock solid.
Whenever ReactOS finishes its operations onto the registry and unlocks it, a lazy flush is invoked to do an eventual flushing of the registry to the backing storage of the system. Except that... lazy flushing never comes into place.
This is because whenever CmpLazyFlush is called that sets up a timer which needs to expire in order to trigger the lazy flusher engine worker. However, registry locking/unlocking is a frequent occurrence, mainly when on desktop. Therefore as a matter of fact, CmpLazyFlush keeps removing and inserting the timer and the lazy flusher will never kick in that way.
Ironically the lazy flusher actually does the flushing when on USETUP installation phase because during text-mode setup installation in ReactOS the frequency of registry operations is actually less so the timer has the opportunity to expire and fire up the flusher.
In addition to that, we must queue a lazy flush when marking cells as dirty because such dirty data has to be flushed down to the media storage of the system. Of course, the real place where lazy flushing operation is done should be in a subset helper like HvMarkDirty that marks parts of a hive as dirty but since we do not have that, we'll be lazy flushing the registry during cells dirty marking instead for now.

- Add a new cmboot.h header to isolate the boot-support definitions
shared with the NT/ReactOS bootloader.
- Move CmpFreeDriverList() to cmboot.c so that we can use it for
cleanup paths in the NT/ReactOS bootloader.
- CmpFindControlSet(): Directly build the control set name in UNICODE,
instead of doing an ANSI->UNICODE conversion.
- Directly assign the CurrentControlSet\Services constant string,
instead of going the route of init-empty-string + append-string.
This is possible since that string is not modified later.
- Remove ASSERT(FALSE), replacing them with correct failure handling.
- Add cleanup paths in CmpAddDriverToList().
- Simplify and fix CmpFreeDriverList(): it's the full DriverNode
that needs to be freed; not the LIST_ENTRY pointer.
- Add other validity checks:
* Registry value types and data sizes;
* For multi-strings, verify that they are NULL-terminated.
* For (multi-)strings, check whether they are NULL-terminated before
optionally removing their trailing NULL character from the count.
Check also whether they are of zero-length and take appropriate
action where necessary.
- Add CmpIsDriverInList() for future usage in CMBOOT compiled in
bootloader mode.
- Add SAL annotations and Doxygen documentation.
- Add debug traces.
- Formatting / code style fixes.
** TODO: Fix SafeBoot support **
Also generate processor identifier properly based on this value
on the Configuration Manager machine-dependent initialization.
Update processor driver INF file accordingly.

If the CPU does support CPUID instruction but does not have the Brand String,
the legacy name detection should be performed either in CIM_Processor (WMI),
in the Processor device driver, or in the application itself.
The deleted Intel CPU name detection code can go to the WMI at some point.
In fact Windows XP and 2003 kernels do not have any strings of that kind.
This effectively reverts the hack committed 6 years ago in 7a985425 (r63798)
that was intended to workaround CORE-7952.
CORE-17413
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
- Sync some INIT_FUNCTION with how they are used and what is already
specified in the headers.
Addendum to commit 85e5b5be (r49445).
- KdbpGetCommandLineSettings(): Remove INIT_FUNCTION.
Fix MSVC 2015 x86 custom build:
"...\ntoskrnl\kdbg\kdb.c(1699): error C2983: 'KdbpGetCommandLineSettings': all declarations must have an identical __declspec(code_seg(...))"
And may also fix obscure bugs when entering into the KDBG debugger.
Probe the data before allocating a copy buffer. Otherwise NtSetValueKey returns an unexpected status code in case of too large data size.
This fixes the NtSetValueKey ntdll api tests.
- KD64: Update the list of supported Debug Filter Masks (KdComponentTable)
with the more up-to-date one from KDBG, that includes some components
that have been added in Vista+, but some of which we also use in ReactOS.
- NtQueryDebugFilterState(), NtSetDebugFilterState() and KdpPrint():
Add the Vista+ behaviour or falling back to the DEFAULT component ID
settings for unknown Components (compiled in only wheen NTDDI_VERSION >= NTDDI_VISTA).
+ Remove redundant comments and update these functions with SAL2 annotations.
- KDBG: Add extra documentation for the debug filter components list.
- CONFIG: Load all the supported Debug Filter Masks settings from the
registry.
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr
- Rework CmpSetSystemValues() and remove its 1st-stage text-mode setup hack, since a real registry hive will be used for 1st-stage either.
- Lock, then unlock the registry in NtInitializeRegistry when initializing the hives & flusher.
- Call CmpInitializeHiveList() (i.e., initialize the other hives like \Software, \User, \.Default) only when we are not in setup-mode.
