[NTOS:PS] Guard the quota in a spin lock (#3419) 
Prior to acquiring a quota from the process and do whatever it's needed to do (charge it or return it back), we must guard ourselves with a spinlock so that we may not get into potential race conditions. In Windows Server 2003, PspGivebackQuota and PspExpandQuota do the same thing and they're the equivalent to PspReturnProcessQuotaSpecifiedPool and PspChargeProcessQuotaSpecifiedPool in our codebase.

[NTOS:PS] Implement PS_QUOTA_TYPE and let the quota code use it (#3389) 
This will replace the PoolIndex variable and as such we'll only be using the PS_QUOTA_TYPE enumeration, as Windows does. Both QuotaEntry, QuotaUsage and QuotaPeak depend explicitly or implicitly on this enumeration. Further details about this enum can be found in the following articles.

Hervé Poussineau 58332b076c [NTOS:KD] Merge initialization phases 1 and 2, and fix log file debugging 
Phase 2 and 3 were not done anymore since 777a2d94da.

Fix that, by merging phases 1 and 2, and by calling phase 3 later
for log file debugging, when ExpInitializationPhase = 3

[NTOS:SE] Do not use a global lock for tokens (#3445) 
In Windows Server 2003 the lock is initialised on a per-token basis, that is, the lock resource is created in SepDuplicateToken() and SepCreateToken() functions. This ensures that the lock initialisation is done locally for the specific token thus avoiding the need of a global lock.
