e7152dc76b Add a target to main.mk that will fail if the amalgamation contains any exported symbols that do not begin with "sqlite3_". Run this target from within releasetest.tcl. Add "static" to a couple of private functions in mem3.c.

c702c7ccdd Use the actual size of memory allocations to update the memory status

actual allocation size.  Ticket #3226. (CVS 5440)

instead of (N+15)&~7 bytes of heap storage.  Minimum heap usage per
allocation is still 16 bytes.  8-byte alignment is preserved. (CVS 4644)
