David Disseldorp ef00eb90e5 s3-vfs: add copy_chunk vfs hooks
copy_chunk copies n bytes from a source file at a specific offset to a
destination file at a given offset. This interface will be used in
handling smb2 FSCTL_SRV_COPYCHUNK ioctl requests.

Use a pread/pwrite loop in vfs_default, so that requests referring to
the same src and dest file are possible.

Provide send and receive hooks for copy chunk VFS interface, allowing
asynchronous behaviour.

Check whether the request source offset + length exceeds the current
size. Return STATUS_INVALID_VIEW_SIZE under such a condition, matching
Windows server behaviour.

/*
* This module implements parseable logging for all Samba VFS operations.
*
* You use it as follows:
*
* [tmp]
* path = /tmp
* vfs objects = full_audit
* full_audit:prefix = %u|%I
* full_audit:success = open opendir
* full_audit:failure = all
*
* vfs op can be "all" which means log all operations.
* vfs op can be "none" which means no logging.
*
* This leads to syslog entries of the form:
* smbd_audit: nobody|192.168.234.1|opendir|ok|.
* smbd_audit: nobody|192.168.234.1|open|fail (File not found)|r|x.txt
*
* where "nobody" is the connected username and "192.168.234.1" is the
* client's IP address.
*
* Options:
*
* prefix: A macro expansion template prepended to the syslog entry.
*
* success: A list of VFS operations for which a successful completion should
* be logged. Defaults to no logging at all. The special operation "all" logs
* - you guessed it - everything.
*
* failure: A list of VFS operations for which failure to complete should be
* logged. Defaults to logging everything.
