Some environment variables provide a space-separated list of strings. It
is easier to process these when they are broken out into an array of
strings.
Add a utility function to handle this.

At present it is not possible to find out which part of the string is the
number part and which is before it. Add a new variant which provides this
feature, so we can separate the two in the caller.

At present this has a minor bug in that it reads the byte before the
start of the string, if it is empty. Also it doesn't handle a
non-numeric prefix which is only one character long.
Fix these bugs with a reworked implementation. Add a test for the second
case. The first one is hard to test.

U-Boot mostly uses hex for value input, largely because addresses are much
easier to understand in hex.
But in some cases a decimal value is requested, such as where the value is
small or hex does not make sense in the context. In these cases it is
sometimes useful to be able to provide a hex value in any case, if only to
resolve any ambiguity.
Add this functionality, for increased flexibility.

Add some tests that check the behaviour of this function. These are the
same as for simple_strtoul() but with a few longer values.

If we see 0x then we can assume this is the start of a hex value. It
does not seem necessary to check for a hex digit after that since it will
happen when parsing the value anyway.
Drop this check to simplify the code and reduce size. Add a few more test
cases for when a 0x prefix is used.

It is a pain to have to specify the value 10 in each call. Add a new
dectoul() function and update the code to use it.

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.
Add a proper comment to simple_strtoul() while we are here.

At present we use the linker list directly. This is not very friendly, so
add a helpful macro instead. This will also allow us to change the naming
later without updating this code.

Align the prefix used in cmd_ut_category function and name of tests
for ut str.
This patch solves the issues detected by "make qcheck" after previous
patch.

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.
Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.
This requires quite a few header-file additions.

Add a helper function for this operation. Update the strtoul() tests to
check upper case as well.

There are quite a few string functions in U-Boot with no tests. Make a
start by adding a test for strtoul().
