50d1b5f363 Remove unnecessary code from malloc.c. Enhance pcache1.c so that is tries 
to reuse existing pages, rather than create new pages, when SQLite is under
memory pressure.  "Memory pressure" means that SQLITE_CONFIG_PAGECACHE memory
is nearly exhausted or sqlite3_soft_heap_limit() has been reached.

92d7652379 When the in single-threaded mode, the sqlite3_mutex_alloc() interface 
still returns a non-NULL value.  The mutex doesn't do anything, but it
tests non-NULL.  This way, extensions (or VFSes) that use sqlite3_mutex_alloc()
can tell the difference between an OOM error and mutexes being disabled.
