Pull smb server updates from Steve French:
- Use after free fixes
- Out of bounds read fix
- Add SMB compression support both at rest and over the wire: support
decompression of compressed SMB2 requests, initially allow compressed
SMB2 READ responses, and implement get/set compression operations for
per-file compression state.
- Credentials fixes: for various FSCTLs, setinfo, delete on close and
for alternate data streams
- Fix access checks and permission checks in DUPLICAT_EXTENTS and
SET_ZERO_DATA fsctls, find_file_posix_info, FILE_LINK_INFORMATION and
smb2_set_info_sec
- Reject non valid session in compound request
- Serialize QUERY_DIRECTORY
- Prevent path traversal bypass by restricting caseless retry
- Path lookup fix
- Two minor cleanup fixes
