This backs out a part of PR 1179 which has a very serious error: If C buffered I/O is available, then printf() and vprintf MUST use it. Otherwise, the ordering of the I/O will be screwed up. They must not use direct file descriptor I/O UNLESS C buffered I/O is disabled.
Functions within the OS must never set the errno value. fs_fdopen() was setting the errno value. Now, after some parameter changes, it reports errors via a negated errno integer return value as do most all other internal OS functions.

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
Fixed coding standard error in several files. Use of while( is incorrect; a space is required between while and (. Also ran tools/nxstyle and fix thoses complaints as well in most files.
Changes to comply with coding standard. Mostly focused on files with missing space after keyword in if(, switch(, and for(. Offending files also got changes to comply with tools nxstyle. If there were logs of nxstyle complaints, the file also got a taste of tools/indent.sh. Still need to fix occurrences of while( with missing space. There are a lot of them.
- 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)
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))

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.
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.
