Fix most of clang -Wcast-align compilation warnings
Unlike gcc, clang is not smart enough to infer the alignment
of structure fields, so add some alignment hints to the code.
* libpam/include/pam_cc_compat.h (PAM_ATTRIBUTE_ALIGNED): New macro.
* modules/pam_namespace/md5.h: Include "pam_cc_compat.h".
(struct MD5Context): Add PAM_ATTRIBUTE_ALIGNED to "in" field.
* modules/pam_namespace/md5.c [!(__i386__ || __x86_64__)]
(uint8_aligned): New type.
[!(__i386__ || __x86_64__)] (byteReverse): Use it instead of
unsigned char.
* modules/pam_timestamp/sha1.h: Include "pam_cc_compat.h".
(struct sha1_context): Add PAM_ATTRIBUTE_ALIGNED to pending field.
* modules/pam_unix/md5.h: Include "pam_cc_compat.h".
(struct MD5Context): Add PAM_ATTRIBUTE_ALIGNED to "in" field.
* modules/pam_unix/md5.c [!HIGHFIRST] (uint8_aligned): New type.
[!HIGHFIRST] (byteReverse): Use it instead of unsigned char.
