drh 4e5e108e83 Avoid excess syncs when padding a transaction in a WAL.

drh cc8d10a0fd Merge the POWERSAFE_OVERWRITE features and the use of statvfs() from the 
statvfs branch into trunk.

drh cb15f35f3b Change the name ZERO_DAMAGE to the more descriptive POWERSAFE_OVERWRITE. 
The query parameter used to control this device characteristic is now "psow".

drh 9291372094 Add interfaces sqlite3_uri_boolean() and sqlite3_uri_int64() which are 
wrappers around sqlite3_uri_parameter() combined with internal routines for
converting strings to booleans and 64-bit integers.

drh 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.

The code is made obsolete by syncing the WAL header.

drh d992b150c7 Refactor the sqlite3WalFrames() routine for clarity of presentation. 
Do the padded transaction sync as the write pointer crosses the final
sector boundary instead of at the end, for efficiency.  Always sync
the WAL header immediately after it is written.

drh 8bbaa89d8d Add SQLITE_IOCAP_ZERO_DAMAGE and enable it for both unix and windows. Use 
this device characteristic to reduce the required work in journaling.
A side effect is that this changes the default page exists back to 1024
even with the use of statvfs().

drh e7d9f13d99 The xTruncate method for the multiplexor now changes surplus overflow 
files to zero-length by default.  Or if the "truncate" query parameter 
is used, it actually deletes the surplus overflow files.  This allows
VACUUM to shrink the database again.
