cf6598193a fs: implement size/fatsize/ext4size
These commands may be used to determine the size of a file without
actually reading the whole file content into memory. This may be used
to determine if the file will fit into the memory buffer that will
contain it. In particular, the DFU code will use it for this purpose
in the next commit.

0a30aa1e7e sandbox: implement exists() function
This hooks into the generic "file exists" support added in an earlier
patch, and provides an implementation for the sandbox test environment.

7eb2c8d573 sandbox: fs: Add support for saving files to host filesystem
This allows write of files from the host filesystem in sandbox. There is
currently no concept of overwriting the file and removing its existing
contents - all writing is done on top of what is there. This means that
writing 10 bytes to the start of a 1KB file will only update those 10
bytes, not truncate the file to 10 byte slong.

If the file does not exist it is created.
