c18b40462b Fix an important bug in the handling of EINTR in unixRead(). Never came 
up on x86 but crashes on sparc.

c02a43afae Only require double-zero terminators on database filenames, not any every 
files supplied to the xOpen method.  This backs out [2544f233f1].  Also
refactor the fillInUnixFile() routine in os_unix.c to reduce the number
of parameters.

9cb5a0d989 Make sure the name of the shared memory file has two zero-terminators in the 
UNIX VFS, so that sqlite3_uri_parameter() will work correctly on that name.

of the syncDir flag to xDelete.  Add an assert to prove that the core only
ever uses that one bit.

f12b3f609f Add the ability to enable or disable SQLITE_IOCAP_ZERO_DAMAGE using a URI 
parameter for both unix and windows.  Add a file-control to query or disable
the ZERO_DAMAGE setting.  Add the -uri option to the "sqlite3" TCL command
in tclsqlite3.c.  Allow the sqlite3_uri_parameter() interface to accept a
NULL pointer for its first parameter.

A side effect is that this changes the default page exists back to 1024
