Log:
When compiling SQLite, enable the SQLITE_OMIT_WAL compile-time option.
We don't use WAL (write-ahead logging) feature of SQLite, but just keeping it
enabled has a visible I/O performance penalty, because SQLite has to check if
the write-ahead log file is present on disk. In a couple of my experiments,
disabling this feature resulted in a ~10% faster `svn st` on a large working
copy.
* subversion/libsvn_subr/sqlite3wrapper.c
(): Define SQLITE_OMIT_WAL.
