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.

cf99fb40c9 This commit moves all of the libraries under a common directory called libs/. This most certainly break libcxx and uClibc++ for now. 
Squashed commit of the following:

    libs/libxx:  Fix some confusing in naming.  If the directory is called libxx, then the library must be libxx.a (unless perhaps LIBCXX is selected).
    libs/:  Fix paths in moved library directories.
    libs:  Brute force move of libc, libnx, and libxx to libs.  Cannot yet build it in that configuration.
