YAMAMOTO Takashi 5edf5e5585 mm: Add CONFIG_MM_PANIC_ON_FAILURE option 
While allocation failure here is not necessarily abnormal enough to
warrant a panic in general, it can be useful in certain situations.

YAMAMOTO Takashi b05320cac2 mm: Move backtrace stuff into a separate option 
The functionality has too much overhead for CONFIG_DEBUG_MM.

YAMAMOTO Takashi c546c0b647 mm: Do not abort on allocation failue with CONFIG_DEBUG_MM 
When allocation failed, it isn't too uncommon for the caller
to fall back to other allocation method.
(eg. esp32 textheap code tries iram heap when an allocation from rtc heap
failed.)
DEBUGASSERT(false) is too much in that case.

This commit removes the DEBUGASSERT, and also makes the heap dump
a separate option.

Petteri Aimonen fe0532c226 Merged in paimonen/nuttx/pullreq_libc_libnx_updates (pull request #757) 
Pullreq libc libnx updates

* NuttX: make strerror() return 'Success' for 0

* NuttX: fix strrchr() so that it considers null terminator as part of string

    From strrchr(3) man page:
    "The terminating null byte is considered part of the string, so that if c
    is specified as '\0', these functions return a pointer to the terminator."

* NuttX: mm_free(): Add DEBUGASSERT()'s to catch memory corruption early.

    It's easier to find the source when asserts fail already when freeing
    an overflowed buffer, than if the corruption is only detected on next
    malloc().

* MM_FILL_ALLOCATIONS: Add debug option to fill all mallocs()

    This is helpful for detecting uninitialized variables,
    especially in C++ code. I seem to be forgetting to initialize
    member variables and then they just get random values..

* NuttX: nxtk_bitmapwindow: Fix warning message when bitmap is fully off-screen.

* nxfonts_getfont: Avoid unnecessary warnings for other whitespace chars also.

* NuttX: Fix kerning of 'I' in Sans17x22 font

    The I character was running together with some other
    characters, e.g. in sequence "IMI".

* NXMU: Revalidate window pointer for mouse events.

    NXMU caches the previous window pointer so that further mouse
    events can be sent to the same window. However, if the window
    is destroyed while mouse button is held down, the pointer may
    become invalid and cause a crash. This patch revalidates the
    pointer before using it.
