- Numbered arguments now work by using two pass parsing and an argument list.
The maximum number of numbered args is determined by CONFIG_LIBC_NL_ARGMAX
which is then copied into NL_ARGMAX.
- Size of pointer argument ('p') is determined before output.
include/limits.h: Define NL_ARGMAX (as well as some of the other 'invariant
values' per http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html)
sched/init/nx_start.c: Add support for CONFIG_BOARD_DRIVER_INITIALIZE. If this option is selected then nx_start() will call a board-provided function board_driver_initialize() immediately after calling up_initialize().
Rename CONFIG_BOARD_INITIALIZE to CONFIG_BOARD_LATE_INITIALIZE.
Raname board_initialize() to board_late_initialize()
The previous implementation was probably corect. On Cygwin with GCC I see this:
int main(int argc, char **argv)
{
printf("Value 1.2 is: [%f]\n", 1.2);
printf("Value 0.1 is: [%f]\n", 0.1);
printf("Value 0.0: [%f]\n", 0.0);
printf("Value 347.6872: [%f]\n", 347.6872);
}
Generates output
Value 1.2 is: [1.200000]
Value 0.1 is: [0.100000]
Value 0.0: [0.000000]
Value 347.6872: [347.687200]
This reverts commit eb0223bc7f.

TODO: Remove 'Missing fscanf()' bug
Clean up remaining complaints for tools/nxstyle
Apply tools/detab, rmcr, convert-comments, lowhex, and indent.sh to the new and highly modified files.

- Move vscanf logic to lib_sscanf.c Switched to stream interface (tricky, because the old implementation used massive read ahead, which isn't suitable for streams, chars already read are gone).
- Added scanf and fscanf
- Added hh, h, and ll modifiers
- Fixes for standard compliance in scanf
- Fixes for standard compliance in strto... function family (don't consume single '-' or '+', allow sign in strotul(l))

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.

1. Move exepath_*() related code to libc/misc
1. Rename exepath_ to envpath_
2. Rename BINFMT_EXEPATH to LIB_ENVPATH
libs/libc/modlib: Add pre module library symbol table support
libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width problem if Issue 35 for the cases of long and long long integer types.
libs/libc/stdio/lib_libvsprintf.c: Resolves the integer field width problem if Issue 35 for the case of integer types.
libs/libc/stdio: Remove CONFIG_NOPRINTF_FIELDWIDTH. That option does, indeed, make the printf family of functions much smaller. But it also adds a lot of complexity and makes the functions non-standard. Removing this might break some of the tinier platforms but it is the best thing to do for long term maintanance for for OpenGroup.org compliance.
When performing a floating point conversion the parsing code could
consume more than required characters from the input buffer. This made
impossible to convert input of form "1.1K" using format "%f%c".
Fix the issue by advancing the input buffer with the actual characters
converted as a float point number.

many locations: Change occurences of open() followed by file_detach() to file_open(). Change most non-controversion calls to open() to nx_open().
fs/inode/fs_fileopen.c: Flesh out file_open() with some interim, placeholder logic.
fs/inode/fs_fileopen.c: Add a framework for a file_open() implementation (no real logic in place yet).
fs/vfs/fs_open.c: Add nx_open() which is the same as open() except that it does not create a cancellation point nor does it modify the errno variable.
