Reset poky to before our libpam hacks

Things got a bit out of synch with openbmc-config due to the libpam
issues and the migration from the meta-* layers.

Revert the two previous commits and then put the latest poky in with the
libpam revert and get openbmc-config right again.

Revert "Revert "libpam: update 1.3.1 -> 1.5.1""

This reverts commit 87ddd3eab4df68e624b5350ccaab28b3b97547c0.

Revert "poky: subtree update:796be0593a..10c69538c0"

This reverts commit c723b72979bfac6362509cf1fe086900f6641f28.

+Subject: [PATCH libX11] cpprules.in: squash whitespace in generated files
+
+CPP is used to generate files, but as cpp reads files from the build host the
+output has a number of blank lines at the beginning which varies depending on
+what GCC and friends is used.
+
+Pathalogical example:
+
+ $ cpp -undef -traditional /dev/null
+ # 1 "/dev/null"
+ # 1 "<built-in>"
+ # 1 "<command-line>"
+ # 31 "<command-line>"
+ # 1 "/usr/include/stdc-predef.h" 1 3 4
+
+ # 17 "/usr/include/stdc-predef.h" 3 4
+
+ [ 40 blank line ]
+
+ # 32 "<command-line>" 2
+ # 1 "/dev/null"
+
+So depending on the content of stdc-predef.h and what other headers CPP will
+load, the amount of whitespace in the generates files varies. This can result in
+differences in reproducible environments, and file conflicts in multilib
+environments.
+
+As whitespace is irrelevant to these machine-readable files, extend the sed to
+just delete blank lines.
