9ef6bc427a Use mkdir() and rmdir() rather than open() and unlink() to create the lock 
files with the unix-dotlock VFS.  The change is backwards compatible and,
we are told, works better on some network filesystems.

both with and without SQLITE_THREADSAFE=0.

b07028f71c Add assert() statements and eliminate needless variable assignments in order 
to get the clang scan-build utility to report zero problems against the
SQLite core.  Clang's static analysis did find one real problem - but it was
in the command-line shell, not in the SQLite core.

20f8e13b44 Formerly, we enabled fdatasync() on linux only. But now we learn that 
fdatasync() is not supported on Android.  So we disable fdatasync() on
Linux too.  It can be reenabled at compile-time for those who really need it.

systems (Ex: AIX and a chromium sandbox) are unable to open and fsync
directories.
