Make sure all memory allocations are 8-byte aligned. Ticket #3040 .
...
Note that the mem3.c memory allocator returns 4-byte aligned memory
allocations. But as mem3.c is intended for use in 32-bit embedded
systems, we are not going to change that. (CVS 4978)

Change the allocator in mem2.c (used when SQLITE_MEMDEBUG is defined) so that allocations are not rounded up to the nearest 4 byte boundary. Fix a couple of errors in malloc.test related to sqlite3OsAccess() returning -1. (CVS 4956)

If memory is leaked when running a test script with the --malloctrace option, write out a file called leaks.sql in the same format as mallocs.sql containing th e leaked applications. The same tools can then be used to examine the stack traces associated with leaked allocations. (CVS 4926)
