`CreateFileMapping` tries to extend the file to the size of mapping
which leads to failure if database was opened in readonly and calculated
mmap size is bigger than the file size.
Providing 0 to `MapViewOfFile` will create a view which has size of
mapping, i.e. file-size in read-only mode and full size if file was
truncated.
Also, swap `sizehi` and `sizelo` names to reflect windows API docs.
This was changed in 1c97a490d for seemingly no reason.

Use the FileLockEx and UnlockFileEx wrappers and the corresponding
LOCKFILE_* and the ERROR_LOCK_VIOLATION error constants from the
golang.org/x/sys/windows package rather than implementing these in the
package.
OpenBSD does not include a UBC kernel and writes must be synchronized
with the msync(2) syscall. In addition, the NoSync field of the DB
struct should be ignored on OpenBSD, since unlike other platforms,
missing msyncs will result in data corruption.
Depends on PR #258.
Fixes#257.
This commit changes Open() to provide an additional Options argument. The options
argument currently only has a Timeout which will cause the Open() to return
ErrTimeout if a file lock cannot be obtained in time.
Fixes#207.
This commit adds Windows support to Bolt. Windows memory maps return an address instead of a byte
slice so the DB.data field had to be refactored to be a pointer to a large byte array.
