newlib: Upgrade 4.2.0 -> 4.3.0

- Rebased fix-rs6000-crt0.patch
- Patch fix_makefile_include_arm_h.patch is no longer required, the newlib
  header dependency has been fixed upstream at 26f9cfd7
- LICENSE checksum change due to:
  - Adding SPDX identifier
  - Deleted Phoenix Systems from License and updated each licenses
  numbers accordingly.
- Add a dummy limits.h header, to make the improved preprocessor
  checks happy during configure.
- Add a patch for libgloss to maintain current behavior of TCLIBC=newlib
  by making libgloss DEPEND on newlib and use its installed headers.
- Switch to git fetcher to simplify fetching the sources and avoid future
  issues due to the way newlib release snapshots were being published.

+Upstream-Status: Inappropriate  [OE-Specific]
+
+Since commit e0c0ad82 libgloss started passing the -nostdinc to CC.
+
+They dont want to build against C library headers that are already in
+the system to avoid pollution, however, we purposely build libgloss
+against the newly built newlib C library, thats why we keep newlib
+and libgloss in separate recipes and create a dependency between them.
+
+This causes an issue where bitbake stops finding newlib headers while
+libgloss is being built.
+
+Do not pass -nostdinc to CC to maintain current behavior of
+TCLIBC=newlib
