fs: tftp: improve file size handling

Previously we used FILE_SIZE_STREAM unconditionally. Instead, fill the
inode size with a valid filesize if we have one and only if not fall
back to FILE_SIZE_STREAM.

fs: tftp: hide files which are actually not present on the server
...
In tftp_lookup we claimed that every desired file is there. This leads
to problems when a user only tests if a file is present and makes
decisions upon this information. Rather than claiming that all files
are present do a tftp_do_open() on the files and see if it is really
there.

When tftp_get_inode() fails it is a sign for a out of memory situtation
rather than an indicator for no space left on the filesystem, so return

fs: dentry cache implementation
...
This adds the Linux dentry cache implementation to barebox.
Until now every filesystem driver resolves the full path to a file for
itself. This leads to code duplication and is error prone since
resolving paths is a complicated task. Also it can narrow down the
lookup performance since barebox only knows ASCII paths and has no way
of caching lookups.
With this patch we get the Linux dcache implementation. The path
resolving code from fs/namei.c is nearly taken as-is, minus the RCU
and locking code. Dcaching is made simple as of now: We simply cache
everything and never release any dentries. Although we do reference
counting for inodes and dentries it is effectively not used yet.
We never free anything until a fs is unmounted in which case we free
everything no matter if references are taken or not.
This patch also contains a wrapper in fs/legacy.c to support
filesystems with the old API.

The full console can still be explicitly enabled with
CONFIG_CONSOLE_RATP.
