Overview
Comment:In test_mutex.c, zero the global structure staticly instead of in Sqlitetest_mutex_Init(). This is because Sqlitetest_mutex_Init() is now called by each thread during thread tests ((6193)). Test code changes only. (CVS 6279)

Modify the test_journal.c code to (1) account for the backup code writing to parts of the pending-byte page when changing a databases page-size, and (2) to avoid reading from the pending-byte page and triggering the assert in os_unix.c. Changes to test code only. (CVS 6280) check-in: 48796216 user: danielk1977 tags: trunk

For the "onefile" demo, pass SQLITE_OPEN_TEMP_DB instead of MAIN_DB to the OS layer when opening the single file. This is to work around the assert() in os_unix.c that tests that the locking region is not written to. (CVS 6278) check-in: 2da076a2 user: danielk1977 tags: trunk
