Ard Biesheuvel 1fbd0ca16a StdLib/LibC ARM AARCH64: do not redefine compiler intrinsics
The memset() function is a compiler intrinsic on AARCH64 and ARM, and
so is memmove() on ARM. Usually, redefining them as LibC currently does
is not a problem since only one version will be selected at link time
from the various static libraries that provide implementations. However,
under LTO, this is slightly different, since explicit references (in the
C code) and implicit references (emitted by the compiler backend) may
resolve to different versions (LTO vs non-LTO), causing conflicts.

So simply omit them for ARM/AARCH64 resp. ARM.

Scott Duplichan 88656abf1b StdLib: Do not define memcpy for AARCH64 builds
For AARCH64, do not define a memcpy function in stdlib because it is
already defined in CompilerIntrinsicsLib.

Harry Liebel 1bc81f4009 StdLib/LibC: Fix ARM symbol problems
StdLibPrivateInternalFiles: Add AArch64 support

Disable 'memcpy' symbol for ARM in LibC. It is already provided by the ARM compiler intrinsics library.
Add missing 'strtold' symbol. Use the same fallback as IPF for now.
Use Include definitions as provided by ARM version.

Daryl McDaniel 3a2f8f4216 StdLib: Fix pointer arithmetic issues in the strncasecmp function.
The original Linux code tried to be too fancy so the internal pointers got out of sync.
Rewrote the function to at least be more clear.
Regardless, it now works properly.

darylm503 53e1e5c647 Add device abstraction code for the UEFI Console and UEFI Shell-based file systems.
Make argv use narrow characters instead of wide characters.
Add setenv functionality.
Add poll() system call.
Change signal names into macros – required for standards compliance.  The enums were renamed and moved to sys/signal.h and the new macros reference the enums.
Added SIGBREAK, which is required for Python.
Modify stdio functions to fail cleanly when called with a NULL File Pointer argument.
Added <sys/cdefs.h> that just includes <sys/EfiCdefs.h>.  By adding this wrapper, we improve compatibility with *nix files which assume <sys/cdefs> exists.
Add <netdb.h>
Added macros for bcopy(), bcmp() and strsep().
Modify the clock() function so that it does not hang when running under an emulation environment such as NT32.
Move TM structure specific macros from the private tzfile.h into <time.h>
Add strncasecmp function.
Add strptime function.
Add gettimeofday function.
Add getcwd function.

darylm503 2aa62f2bc9 Standard Libraries for EDK II.
This set of three packages: AppPkg, StdLib, StdLibPrivateInternalFiles; contains the implementation of libraries based upon non-UEFI standards such as ISO/IEC-9899, the library portion of the C Language Standard, POSIX, etc.

AppPkg contains applications that make use of the standard libraries defined in the StdLib Package.

StdLib contains header (include) files and the implementations of the standard libraries.

StdLibPrivateInternalFiles contains files for the exclusive use of the library implementations in StdLib.  These files should never be directly referenced from applications or other code.
