d3a07ca26c libs/printf: add support for print symbol name 
Show a '%p' thing.  A nuttx extension is that the '%p' is followed
by an extra set of alphanumeric characters that are extended format
specifiers.

* - 'S' For symbolic direct pointers (or function descriptors) with offset
* - 's' For symbolic direct pointers (or function descriptors) without offset

printf("%ps %pS\n", ptr, ptr) will print:

module_start module_start+0x0/0x62

c11c1dc8fd libs/libc/stdio: replace double_t to double 
Modify reason:

When build Nuttx SIM, in x86_64 system:

Compile with gcc option '-m64' (default):
sizeof(double_t) = 8
sizeof(double)   = 8

Compile with gcc option '-mx32':
sizeof(double_t) = 8
sizeof(double)   = 8

Compile with gcc option '-m32':
sizeof(double_t) = 12       // long double
sizeof(double)   = 8

When use '-m32', and print sth. like this:
printf("%f\n", (double)3.0);
SIM will print out: nan

This is because sizeof(double_t) is not equal with double.

Resolve:
replace all double_t to double in libs/libc/stdio.

As a user of '-m32', you should know double_t is one type
long double, and len is 12. And you use use '%lf' to print.
like:
printf("%lf\n", (double_t)3.0);

Currently we don't support '%lf'.

38e93ede2b Revert "libs/libc/stdio: Fix the %f floating point output format." 
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]

Author: Johannes <nivus.entwicklung@gmail.com>

    - 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))

055810d9a4 libs/libc/stdio/lib_libvsprintf.c: Correct handling of integer 'precision' in all justification types for values 9, 99, 999, 9999, 99999: 
Right justification:
  009   099   999  9999 99999  %5.3u
    9    99   999  9999 99999  %5u

Right justification, zero padding
  009   099   999  9999 99999  %05.3u
00009 00099 00999 09999 99999  %05u

Left justification
009   099   999   9999  99999  %-5.3u
9     99    999   9999  99999  %-5u

c958dc0f22 libs/libc/stdio/lib_libvsprintf.c: Back out most of commit d0254b1c79. While logic seemed correct, verify against glibc showed differs. The output now matches the output form glibc: 
This code sequence:

  printf("%3.3u %3.3u %3.3u %3.3u %3.3u\n",
         9, 99, 999, 9999, 99999);
  printf("%3u %3u %3u %3u %3u\n",
         9, 99, 999, 9999, 99999);
  printf("%3.3lu %3.3lu %3.3lu %3.3lu %3.3lu\n",
         9L, 99L, 999L, 9999L, 99999L);
  printf("%3u %3u %3u %3u %3u\n",
         9L, 99L, 999L, 9999L, 99999L);
  printf("%3.3llu %3.3llu %3.3llu %3.3llu %3.3llu\n",
         9LL, 99LL, 999LL, 9999LL, 99999LL);
  printf("%3llu %3llu %3llu %3llu %3llu\n",
         9LL, 99LL, 999LL, 9999LL, 99999LL);

Generates:

009 099 999 9999 99999
  9  99 999 9999 99999
009 099 999 9999 99999
  9  99 999 9999 99999
009 099 999 9999 99999
  9  99 999 9999 99999

For both NuttX and glibc.

d0254b1c79 Squashed commit of the following: 
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.

b01e6e5f2a libs/libc/stdio/lib_sscanf.c: Fix conversion for format specifiers that appear right after a floating point format specifier 
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.

a7fd58c4db Squashed commit of the following: 
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.
