9bf3da8eab Add a mutex around an sqlite3StatusAdd() call to prevent the pagecount 
overflow measurements from getting off in multithreaded applications.

6d4fb833b7 Update mutex1.test so that it works with the memsubsys1 permutation (pagecache memory). Change a few instances of SQLITE_MUTEX_STATIC_LRU2 in comments and test code to STATIC_PMEM.

25ca568251 Rename the PCache1.mxPinned field to n90pct (since it is 90% of nMax) in order 
to distinguish it from PGroup.mxPinned.  Fix the computation of n90pct so that
it does not overflow adversely on excessively large cache sizes.

bee29f4ac1 Do not use mutexes in the pcache implementation unless 
SQLITE_ENABLE_MEMORY_MANAGMENT is defined.  This is a performance enhancement.
A side effect is that pcaches will not steal pages from one another unless
ENABLE_MEMORY_MANAGEMENT is set, or unless SQLITE_THREADSAFE=0.
