write() uses a const pointer so write_full should do the same.

Our asprintf and vasprintf have different prototypes than the glibc
functions. This causes trouble when we want to share barebox code
with userspace code. Change the prototypes for (v)asprintf to match
the glibc prototypes. Since the current (v)asprintf are convenient
to use change the existing functions to b(v)asprintf.

libfile is a collection of helpers for handling files. open_and_lseek()
is a perfect match for this, so move it there.

Some character devices may perform meaningful operations in their
implementation of close() -- a good example would be socfpga.c which
checks if the FPGA was programmed succesfully in it's close() method
-- so ignoring return value of this call may cause false positives in
checking exit status for success.

Set return value correct in error case.
This prevents barebox from crashing in some conditions.

read_file has some limitations:
- It is not possible to check the error code since read_file returns
NULL for failure
- It is not possible to limit the buffer size to sensible limits.
This patch introduces read_file_2 which doesn't have these limitations.
read_file becomes a wrapper around read_file_2.

We have our file helper functions in several places. Move them
all to lib/libfile.c.
With this we no longer have file helpers in fs/fs.c which contains
the core fs functions and no functions in lib/libbb.c which are
not from busybox.
