Denys Vlasenko daa66ed62c ash: fix use-after-free in pattern substituon code 
Patch by soeren@soeren-tempel.net

The idx variable points to a value in the stack string (as managed
by STPUTC). STPUTC may resize this stack string via realloc(3). If
this happens, the idx pointer needs to be updated. Otherwise,
dereferencing idx may result in a use-after free.

Denys Vlasenko 002d6ee46d ifplugd: split -a into -a and -A, latter disables upping in iface creation 
-a meant both "don't up iface before each link detection" and "don't up iface
when it newly appears". But they are not the same.

I have a dock station where eth1 appears when I attach the notebook to it
(looks like it's hanging off a USB bus). IOW: appearance of this interface
is functionally equivalent to attaching ethernet cable.
ifplugd meant to be able to *automatically* handle this case.
Currently, with -a, it couldn't: newly appearing iface stayed down,
user had to manually up it.

Denys Vlasenko 205042c07a libbb/sha1: in unrolled x86-64 code, pass initial W[] in registers, not on stack 
This can be faster on some CPUs.
On Skylake, evidently load latency from L1 (or store-to-load
forwarding in LSU) is fast enough to completely hide
memory reference latencies here.
