Overview
Comment:Make sure to flag benign malloc failures in the Windows VFS as such. Expand use of the DO_OS_MALLOC_TEST to cover the VFS functions that can now return an out of memory error. Support an experimental --match option to the test suite that will run only those tests matching the specified pattern.

Remove use of malloc and free from the Windows VFS. Also, prevent sqlite3BtreeOpen from assuming that sqlite3OsFullPathname cannot fail. (check-in: 8966ec17 user: mistachkin tags: winSyscall)
