[PATCH] FS_SECTOR_SIZE_INFORMATION and FSCTL_FILE_LEVEL_TRIM

[David Disseldorp]

This patch-set adds client and server support for the query-info 
FS_SECTOR_SIZE_INFORMATION level. This info level provides sector
alignment information for an underlying share volume, as well as
NO_SEEK_PENALTY and TRIM_ENABLED flags useful for SSD /
thin-provisioned storage detection.

Additional changes are included to provide basic FSCTL_FILE_LEVEL_TRIM
testing. The test is dependent on the TRIM_ENABLED query-info flag,
otherwise it's skipped.

Feedback appreciated.

Cheers, David
