crc: import crc_itu_t() from kernel ...

Our cyc_crc16() function is the same function as crc_itu_t() in the
Linux kernel. Import and use crc_itu_t() from the Kernel for
consistency.

libfile: Fix incorrect lseek check in open_and_lseek() ...

We can't use "int" to capture output of lseek which is "loff_t", since
former does not cover all of the range of the values of the latter and
any pos >= 0xffff_ffff will result in a false positive "failure". To
avoid that replace the check to check that new position matches what
was requested.

commands: Move mem_parse_options() to lib/misc.c ...

As a first step of de-cluttering /dev/mem related code, move
mem_parse_options() out of commands/mem.c into lib/misc.c where it
seem to fit better. With this change we no longer explicitly turn this
code off using CONFIG_COMPILE_MEMORY and instead rely on LTO to get
rid of it when it's not being used.

While at it, also fix return value by replacing COMMAND_ERROR_USAGE
with -EINVAL. All of the callers of mem_parse_options() expect
negative error code as a sign of failure and COMMAND_ERROR_USAGE is
not negative.

recursive_action: add ACTION_SORT flag ...

Add a flag to sort directory entries before recursing into them.

Since this part of lib/ is used inside barebox as well as in
scripts/bareboxenv.c, we cannot easily use stringlists from lib/, which
would have made the code a bit nicer.

Add generic implementation for muldi3 ...

Since version v2018.08.0 some shared copies of gcc routines got added to
barebox so that archs don't need to have their own copy inside their
lib. The arch I am working on atm also needs support for muldi3 which is
not present as a generic version right now.

This patch adds the generic version from latest linux v4.20 to barebox
and lets the archs select it in their Kconfig so they don't need to
provide it themself.

lib: lodepng: remove useless test ...

Either the condition 'code_ll==(unsigned int)(-1)' is redundant or the
array 'LENGTHBASE[29]' is accessed at index 4294967038, which is out of
bounds.

On other hand this condition is tested within other scope:
"if(code_ll >= FIRST_LENGTH_CODE_INDEX && code_ll <= LAST_LENGTH_CODE_INDEX)"
with is already limited to (code_ll >= 257 && code_ll <= 285),
so it can't be -1 any way.

All other error cases in read_file_2() are handled gracefully, so
there shouldn't be any reason not do so for the case of trying to
allocate too much memory. This error path can be easily triggered
with:

barebox_update file-bigger-than-availible-ram.img

Currently this would result in a crash which is not really desirable
from user experience.

Comments in include/kfifo.h state that the FIFO size will be rounded up

kfifo support was added.

Fix that now and do what the comments state.
