303b02cc0b Fix an LSM problem causing the wrong amount of "auto-work" to be performed 
under fairly obscure circumstances.

34aebb88da Change some LSM code internal typenames from "Blob" and "Pgno" to "LsmBlob" 
and "LsmPgno". This allows the LSM code to be compiled as a single unit with
sqlite3.c.

cda185d3a2 Ensure that empty space on pages is zeroed before they are written to disk. 
This helps with compressed databases, and stops valgrind complaining about
uninitialized bytes and write().

b5ef728db6 In lsm (not SQLite), avoid opening the *-shm file before the database file is 
locked. Otherwise, there is a race condition whereby a connection in another
process process may unlink() it while it is still in use.
