f41d3eeeb7 Add MICROPY_FLOAT_CONST to all fp constants. 
In order to get ulab to compile correctly against single floating point 
all of the constants need to switch to single format. Conveniently 
MicroPython has provided a macro to manage this switch. Use this 
througout.

Unfortunately also introduces a bunch of whitespace changes because 
there is a mass of trailing whitespace in the codebase and my editor is 
(correctly) configured to remove this.

not compatible with '_thread' module 
ulab not compatible with enabling '_thread' module from the make command :
- building ulab with thread enabled in MicroPython :
`$ make -j8 CFLAGS_EXTRA='-DMICROPY_PY_THREAD=1' BOARD=PYBV11 USER_C_MODULES=../../../ulab all`
yields a firmware with '_thread' module but without 'ulab' module, because 'CFLAGS_EXTRA' is used in the make command and in 'ulab/code/micropython.mk', so the value of the last is ignored;
- the solution is to use 'override' and '+=' in in last line of 'ulab/code/micropython.mk' :
`override CFLAGS_EXTRA += -DMODULE_ULAB_ENABLED=1`

d0b11a6081 polyfit: Argument handling improvements 
* In the 3-args case, the lengths of the arguments were not checked
 * in the 3-args case, the type of the 2nd argument was not checked
 * gcc falsely diagnosed a `maybe-uninitialized` variable because it
   did not see that the branches of the if() statement were mutually
   exclusive

It's this third issue that originally drew my attention to this code,

daf4b07ef7 Fix -Wunused-parameter diagnostics 
Here we actually get bugs fixed!  At many sites, mp_parse_arg_all's
first argument was the number of positional arguments required, rather
than the number actually supplied.

This fixes e.g., the bug where the linspace third positional argument
was not used as the "num" argmuent, and where too many positional args
were not treated as an error:

    >>> ulab.linspace(0, 1, 9)
    array([0.0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875, 1.0], dtype=float)
    >>> ulab.linspace(0, 1, 1, 1)
    TypeError: extra positional arguments given

In the case of argmin/argmax of an iterable, it is now signaled to the user
that only the axis=None case is supported, instead of giving a wrong
result.

22605c6fe9 Fix -Wshadow diagnostics 
A declaration of a local variable can "shadow" a parameter or another
local variable declared in an outer scope.

Since this can create confusion about which variable is referred to, it
is better to fix these diagnostics.

A variety of changes were made:
 - Add curly braces to reduce the scope of a variable (ndarray_unary_op)
   so that its scope has ended before the next scope where it is used
 - be consistent about whether a variable is declared with for-loop scope
   or not (ndarray_print_row)
 - remove a declaration so that the outer variable is used, after verifying
   this will function properly (insert_slice_list)
 - rename a variable introduced by a macro (RUN_SUM, RUN_STD) so it does
   not shadow another variable

11ed69dacf Fix -Wmissing-prototypes diagnostics 
This diagnostic flag, enabled by default in CircuitPython, requires that
nonstatic functions have a previous prototype.  Since placing prototypes
in header files is the only way that mismatched arguments between function
definition and use sites can be detected, this is a valuable warning.

In the case of ulab, the majority of the  changes required were to mark
functions as "static" that were used only in a single C source file.

3dc52575f0 slice_length: avoid implementation-defined division by negative number 
In CircuitPython (only), a the slice assignment to [-1👎-3] of an
ndarray of length 1 caused a crash.  This appears to be because in
CircuitPython, the internal pointer of an empty array was NULL rather than
pointing at some memory which happened to be valid and assignable.

This appears to be a corner case of how integer promotion rules work in C.
The expression `slice.stop - slice.start + (slice.step + correction)`
is type `unsigned long` and on a LP64 platform its value is
18446744073709551614.  This led to the function returning that this slice
had length 1 instead, during the automated tests.

By casting to signed types capable of holding indices and sizes, the
problem is corrected on both platforms.

f9fabc5079 Fix handling of negative indices 
I don't know why, but mp_seq_get_fast_slice_indexes adjusts "stop" in a
surprising way, and that led to the (remaining) differences in slicing
between ulab and built-in lists.

    // If the index is negative then stop points to the last item, not after it
    if (indexes->step < 0) {
        indexes->stop++;
    }

Call the underlying routine, mp_obj_slice_indices, instead.
