Hermès Bélusca-Maïto 24cb57fdea [BOOT][SDK:RTL] Compile a reduced RTL library for FreeLdr / NT bootloader...
... as it should have always been done (and must be done for NTDLL
and NTOS kernel as well). This allows using the RTL with the correct
definitions and the reduced functionality available at boot-time.

+ Make the RTL main header compatible.

In addition, this will permit re-using existing code that already
uses the RTL (mostly string conversions).

See commits 427c90af3 (r36761) and b46e8cc18 (r36980) for some
background.

RTL restrictions:

ExAllocatePool (and friends) must be used exclusively. RtlAllocateHeap (and friends) must NOT be used! ExAllocatePool (and friends) translate to RtlAllocateHeap (and friends) in ntdll\rtl\libsupp.c.

RtlEnterCriticalSection (and friends) must be used exclusively. ExAcquireFastMutex (and friends) must NOT be used! RtlEnterCriticalSection (and friends) translate to ExAcquireFastMutex (and friends) in ntoskrnl\rtl\libsupp.c. This means that RtlEnterCriticalSection (and friends) can NOT be used recursively in RTL. The reason for choosing RtlEnterCriticalSection (and friends) over ExAcquireFastMutex (and friends) is that the FAST_MUTEX struct is smaller than the RTL_CRITICAL_SECTION struct.
