Changes

• 3668 OLPC - save-mfg-data, simplify SN processing code following #12695 review. No functional change.
• 3667 OLPC - check for a NUL before removing it from the SN tag search result, because otherwise an SN tag with zero length may prevent normal boot. #12695
• 3663 OLPC - do not leave keyboard locked if file cannot be created by save-mfg-data on XO-1.5. #12684.
• 3662 OLPC - avoid duplicate file creation. #12684.
• 3659 OLPC XO-1 - backport lid and ebook switch test, #12514.
• 3658 disklabel - abort open if the partition has a type for a filesystem that is not present in the build. Fixes failure to boot when an NTFS filesystem is present on an unsecured system. OLPC #12678.
• 3651 OLPC XO-1 - suppress the RTC amnesia check introduced in r3649, because the VRT bit works fine, and the century value at 0x1a is occasionally cleared by a power cycle. This clearing is ingored by ds1385r.fth get-time, which forces the returned century to 0x20. Curiously, the century value at 0x32 (as set by MSR 5140.0057) is not used in ds1385r.fth, and keeps what Linux set it to.
• 3650 OLPC XO-1 XO-1.5 - maintain the NFS RPC XID in CMOS RAM, so that scripted NFS actions do not fail silently. Different location used for XO-1 because the default location is reset by a power cycle. #12662.
• 3649 OLPC XO-1.5 - the Valid RAM and Time (VRT) bit in RTC register 0xd can't be trusted on the XO-1.5, so use other means to detect loss of data. This works in most cases, but there is still the possibility of data corruption when the battery is missing or discharged. #12600.
