Jérôme Gardou 8494688eeb [NTOS:MM] Do not use atomic operations to set a bit while holding a lock.

Jérôme Gardou f06b58925d [NTOS:MM] Implement shrinking big pool allocation table
Shrink when using 1/8 of its allocated capacity (thus use 25% of it at the end of the process)
Expand when using 3/4 of its allocated capacity (thus use ~40% of it at the end of the process)

Timo Kreuzer 24f240be8a [NTOS] On DBG builds, fill pool allocations with 0xCD and freed pool with 0xDD
This matches what the MSVC runtime does with heap allocations on debug builds.

[NTOS] Just go ahead and allow printing all the printable ASCII characters in ExpTagAllowPrint().
As documented in https://docs.microsoft.com/fr-fr/windows-hardware/drivers/ddi/wdm/nf-wdm-exallocatepoolwithtag
pool tag "characters" must be a value in the range 0x20 (space) to 0x7E (tilde),
which happen indeed to be the range of printable (non-extended) ASCII characters.

(The display problem was originally caught while attempting to display
the pool tag 0x3a306847 corresponding to 'Gh0:', a win32ss GDIOBJ pool tag
encoded with macro GDIOBJ_POOL_TAG().)

Serge Gautherie 84e76b1c4c [NTOS:MM] ExFreePoolWithTag(): Accept tag mismatch, on release build only (#1334)
"Release" builds should not BSoD on 'Freeing pool - invalid tag specified' case,
this is compatible with Windows behaviour.
Nothing changes otherwise concerning the "Debug" builds, where pool-tag mismatch
triggers a BSoD as expected.

[NTOS:MM] Dump pool consumers at most once per second.
This should avoid some log spam during kmtest:ExPools, which
intentionally depletes pool.

[NTOSKRNL] Reimplement !irpfind using !poolfind helpers
This allows avoiding one of the previous implementation limits:
leaked IRP not queued to a thread are now totally visible since
we look directly in the memory pool.

[NTOSKRNL] Implement !poolfind command in KDBG
For now, it allows searching for pool allocations in
both paged and non paged pool.

It is based on Andreas Schuster work to identify POOL_HEADER
structures.

[NDK][NTOS] Add global definition of INIT_FUNCTION/INIT_SECTION (#779)
* 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

[NTOSKRNL] Don't call OOM dumper in case we were trying to allocate more than 100 pages.
In such case, we'll consider the caller is bogus and we'll fail in silence.

Pierre Schweitzer 149e1a2610
[NTOSKRNL] Add a non paged memory dumper in case of low memory situation.
Its purpose is to dump the non paged consumption, tag by tag,
to allow tracking potential faulting driver in case ReactOS starts lacking memory.
This will look like what !poolused outputs, even though it doesn't deal with paged pool.

Thanks to Thomas for his kind review and improvement suggestions.
