1f5786f5ea libc/stdlib: Fix range check in strtoul(l)
The previous implementation of strtoul(l) is flawed. The range check
assumed that when overflow happens, the truncated value is smaller than
the original value. As a counter example, passing "10000000000" to
strtol will not trigger ERANGE, but return a truncated value. This patch
adds more accurate range checks.

66052f7c4c mkstemp: Only look at the trailing Xs
As it's stated in the standards.

The original code look at the first Xs. It can end up with
an unexpected behavior, if a template contains multiple series of Xs.

67ec3d7926 Remove CONFIG_CAN_PASS_STRUCT
This commit resolves issue #620:

Remove CONFIG_CAN_PASS_STRUCTS #620

The configuration option CONFIG_CAN_PASS_STRUCTS was added many years ago to support an old version of the SDCC compiler. That compiler is currently used only with the Z80 and Z180 targets. The limitation of that old compiler was that it could not pass structures or unions as either inputs or outputs. For example:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    struct mallinfo mallinfo(void);
    #else
    int      mallinfo(FAR struct mallinfo *info);
    #endif

And even leads to violation of a few POSIX interfaces like:

    #ifdef CONFIG_CAN_PASS_STRUCTS
    int  sigqueue(int pid, int signo, union sigval value);
    #else
    int  sigqueue(int pid, int signo, FAR void *sival_ptr);
    #endif

This breaks the 1st INVIOLABLES rule:

Strict POSIX compliance
-----------------------

  o Strict conformance to the portable standard OS interface as defined at
    OpenGroup.org.
  o A deeply embedded system requires some special support.  Special
    support must be minimized.
  o The portable interface must never be compromised only for the sake of
    expediency.
  o Expediency or even improved performance are not justifications for
   violation of the strict POSIX interface

Also, it appears that the current SDCC compilers have resolve this issue and so, perhaps, this is no longer a problem: z88dk/z88dk#1132

NOTE:  This commit cannot pass the PR checks because it depends on matching changes to the apps/ directory.

Author: Gregory Nutt <gnutt@nuttx.org>

    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.

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))

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.
