c60dd72a2a Support memdump to realize incremental dump function
Add a new field to record the global on the basis of mm_backtrace.
When using alloc, the field is incremented by 1,
so that the memory usage can be dumped within the range

5a298e8685 mm: memory allocations return valid pointer when request 0 size
This change introduce 2 items:
1. If the size of the space requested is 0, the behavior is implementation-defined:
   either a null pointer shall be returned, or the behavior shall be as if the size
   were some non-zero value, except that the behavior is undefined if the returned
   pointer is used to access an object.

   Change the behavior to be similar to Linux and Android and allocates an object
   of a minimum size instead of returning null pointer.

   https://pubs.opengroup.org/onlinepubs/9699919799/functions/malloc.html
   https://pubs.opengroup.org/onlinepubs/9699919799/functions/calloc.html
   https://pubs.opengroup.org/onlinepubs/9699919799/functions/realloc.html

2. The description of realloc() has been modified from previous versions of this
   standard to align with the ISO/IEC 9899:1999 standard. Previous versions explicitly
   permitted a call to realloc (p, 0) to free the space pointed to by p and return
   a null pointer. While this behavior could be interpreted as permitted by this
   version of the standard, the C language committee have indicated that this
   interpretation is incorrect. Applications should assume that if realloc() returns
   a null pointer, the space pointed to by p has not been freed. Since this could lead
   to double-frees, implementations should also set errno if a null pointer actually
   indicates a failure, and applications should only free the space if errno was changed.

   Do not free memory of zero-length reallocation is requested

67ec3d7926 Remove CONFIG_CAN_PASS_STRUCT
This commit resolves issue #620:

Remove CONFIG_CAN_PASS_STRUCTS #620

The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    struct mallinfo mallinfo(void);
    #else
    int      mallinfo(FAR struct mallinfo *info);
    #endif

And even leads to violation of a few POSIX interfaces like:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    int  sigqueue(int pid, int signo, union sigval value);
    #else
    int  sigqueue(int pid, int signo, FAR void *sival_ptr);
    #endif

This breaks the 1st INVIOLABLES rule:

Strict POSIX compliance
-----------------------

  o Strict conformance to the portable standard OS interface as defined at
    OpenGroup.org.
  o A deeply embedded system requires some special support.  Special
    support must be minimized.
  o The portable interface must never be compromised only for the sake of
    expediency.
  o Expediency or even improved performance are not justifications for
   violation of the strict POSIX interface

Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132

NOTE:  This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.

cc90d586c0 A workaround for macOS linker
It seems that "ld -r" on macOS doesn't include objects from
libraries for common symbols. Because of that, sim build
ends up with undefined references to globals like g_binfmts
