Add HiSilicon's 0x48/0xd40 Cortex-A76 variant.
Both Kirin 980 and Kirin 810 feature big cores with 0x48/0xd40 ID though they are marketed/documented as Cortex-A76 by HiSilicon themselves. Kirin 980 shows a r1p0 stepping while newer 810 has r3p0.

lsfd: remove strcpy(), keep things based on sizeof()
* use safe xstrncpy() rather than strcpy()
* use sizeof() for static buffers rather than macro with real size
(this solution is more robust for future code changes)
* use xcalloc() to zeroize allocated memory

It's probably typo in the original path (too many brackets:-)). Let's
be explicit about the types used in the calculation. '1 << n' means
the left shift is on 'int', but we need '(t)1 << n'.

lib/blkdev: set errno in more cases
Applications evaluate errno in case of a -1 return value. Examples
within util-linux are fsck.cramfs and mkfs.minix. Set errno more often
to offer reasonable error codes to the application and user.

lib/blkdev: handle interrupted read call
The read call may fail if it is interrupted by a signal. Do not assume
that we have reached the end of the underlying block device because of
this. Use read_all which retries in these cases.

mkswap: do not use uninitialized stack value
If blkdev_get_size fails, then size is not set. Exit with an error code
and indicate what went wrong instead of continuing with random stack
content.
Proof of Concept:
```
$ mkswap /dev/null
mkswap: warning: truncating swap area to 17179869180 KiB
mkswap: /dev/null: insecure permissions 0666, fix with: chmod 0600 /dev/null
mkswap: unable to assign device to libblkid probe
```
The first output line depends on stack content and sometimes does not
show up at all. Abort operation if argument is neither regular file nor
block device.

copies relevant license headers from lib/ to include/ to keep

login: never send signals to init
If the signal handler is triggered after a failed fork attempt, then
child_pid will be -1. This in turn leads to a positive test and a
subsequent call of kill(1, signal). If signal was SIGTERM, then there
will be also another kill(1, SIGHUP) call.
Test explicitly for a positive child_pid value to prevent these cases.

unshare: support --map-users=inner:outer:count as well as outer,inner,count
The argument ordering in /proc/self/[gu]id_map and mount -o X-mount.idmap
is consistently inner:outer:count but unshare --map-users and --map-groups
were originally defined to expect outer,inner,count instead.
To reduce confusion caused by this mismatch, support a colon-separated
inner:outer:count ordering as well as the original comma-separated
outer,inner,count argument format. Although we accept both formats, only
document the new one in the usage text and deprecate the old format in
the man page.
