UPSTREAM: fs: add fs_readdir()

Needed to support efi file protocol. The fallback.efi loader wants
to be able to read the contents of the /EFI directory to find an OS
to boot.

Modelled after POSIX opendir()/readdir()/closedir(). Unlike the other
fs APIs, this is stateful (ie. state is held in the FS_DIR "directory
stream"), to avoid re-traversing of the directory structure at each
step. The directory stream must be released with closedir() when it
is no longer needed.

fs: API changes enabling extra parameter to return size of type loff_t

The sandbox/ext4/fat/generic fs commands do not gracefully deal with files
greater than 2GB. Negative values are returned in such cases.

To handle this, the fs functions have been modified to take an additional
parameter of type "* loff_t" which is then populated. The return value
of the fs functions are used only for error conditions.

rather than:

This prevents errors being printed by attempts to load non-existent
files, which can be important when checking for a large set of files,
such as /boot/boot.scr.uimg, /boot/boot.scr, /boot/extlinux.conf,
/boot.scr.uimg, /boot.scr, /extlinux.conf.

fs: fix generic save command implementation

Fix a few issues with the generic "save" shell command, and fs_write()
function.

1) fstypes[].write wasn't filled in for some file-systems, and isn't
checked when used, which could cause crashes/... if executing save
on e.g. fat/ext filesystems.

2) fs_write() requires the length argument to be non-zero, since it needs
to know exactly how many bytes to write. Adjust the comments and code
according to this.

3) fs_write() wasn't prototyped in <fs.h> like other generic functions;
other code should be able to call this directly rather than invoking
the "save" shell command.

Fix number base handling of "load" command

As documented, almost all U-Boot commands expect numbers to be entered
in hexadecimal input format. (Exception: for historical reasons, the
"sleep" command takes its argument in decimal input format.)

This rule was broken for the "load" command; for details please see
especially commits 045fa1e "fs: add filesystem switch libary,
implement ls and fsload commands" and 3f83c87 "fs: fix number base
behaviour change in fatload/ext*load". In the result, the load
command would always require an explicit "0x" prefix for regular
(i. e. base 16 formatted) input.

Change this to use the standard notation of base 16 input format.
While strictly speaking this is a change of the user interface, we
hope that it will not cause trouble. Stephen Warren comments (see
[1]):

I suppose you can change the behaviour if you want; anyone
writing "0x..." for their values presumably won't be
affected, and if people really do assume all values in U-Boot
are in hex, presumably nobody currently relies upon using
non-prefixed values with the generic load command, since it
doesn't work like that right now.

fs: rename fsload command to load

When the generic filesystem load command "fsload" was written, I felt
that "load" was too generic of a name for it, since many other similar
commands already existed. However, it turns out that there is already
an "fsload" command, so that name cannot be used. Rename the new
"fsload" to plain "load" to avoid the conflict. At least anyone who's
used a Basic interpreter should feel familiar with the name!

fs: fix number base behaviour change in fatload/ext*load

Commit 045fa1e "fs: add filesystem switch libary, implement ls and
fsload commands" unified the implementation of fatload and ext*load
with the new command fsload. However, this altered the interpretation
of command-line numbers from always being base-16, to requiring a "0x"
prefix for base-16 numbers. Enhance do_fsload() to allow commands to
specify which base to use.

Use base 0, thus requiring a "0x" prefix for the new fsload command.
This feels much cleaner than assuming base 16.

Use base 16 for the pre-existing fatload and ext*load to prevent a
change in behaviour.

Use base 16 exclusively for the loadaddr environment variable, since
that variable is interpreted in multiple places, so we don't want the
behaviour to change.

Update command help text to make it clear where numbers are assumed to
be hex, and where an explicit "0x" prefix is required.

fs: add filesystem switch libary, implement ls and fsload commands

Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load},

extended to other filesystem types; I only didn't do it for zfs because
I don't have any filesystems of that type to test with.

too.
