2e4d526996 Fix the pager such that if the xOpen() message sends back the SQLITE_OPEN_MEMORY
flag, the pager is opened in journal-mode MEMORY, even if compiled with
SQLITE_OMIT_DESERIALIZE.  No changes to the logic as long as that OMIT flag
is omitted.  We need to better document the behavior of xOpen to describe this.

7520116441 Simplify a memcpy() in defragmentPage(). It now might copy more content than
is strictly necessary, but runs faster and uses less code space.  Possible
reasons for the improved performance:
(1) the copy is now always 8-byte aligned,
(2) fewer intermediate results are required which means less register
pressure which helps the compiler to optimize the subroutine.
