It appears that no one ever run ffs-test on a big-endian machine,
since it used cpu-endianess for fs_count and hs_count fields which
should be in little-endian format. Fix by wrapping the numbers in
cpu_to_le32.

Commit [ac8dde11: “usb: gadget: f_fs: Add flags to descriptors block”]
which introduced a new descriptor format for FunctionFS removed the
usb_functionfs_descs_head structure, which is still used by ffs-test.
tool.
Convert ffs-test by converting it to use the new header format. For
testing kernels prior to 3.14 (when the new format was introduced) and
parsing of the legacy headers in the new kernels, provide a compilation
flag to make the tool use the old format.
Finally, include information as to when the legacy FunctionFS headers
format has been deprecated (which is also when the new one has been
introduced).

The out functions should only handle actual available data instead of the complete buffer.
Otherwise for example the ep0_consume function will report ghost events since it tries to decode
the complete buffer - which may contain partly invalid data.

Use the header file in tools/include instead of duplicating the endian
functions.

The m.nazarewicz@samsung.com email address is no longer valid,
so this commit replaces it with mina86@mina86.com which is
employer-agnostic and thus should be valid for foreseeable
feature.

When compiling this program the functionfs.h header cannot be found, producing:
ffs-test.c:40: fatal error: linux/usb/functionfs.h: No such file or directory
This patch also fixes the following warning:
ffs-test.c:453: warning: format ‘%4d’ expects type ‘int’, but argument 3 has type ‘size_t’

This adds an example user-space FunctionFS driver which
implements a source/sink interface used for testing.
