libc/resolv: Switch default to loopback address
If no resolver configuration was found, we would fall back to INADDR_ANY
and IN6ADDR_ANY. This made sense when it was first written thirty or
forty years ago but not today, especially since connecting to INADDR_ANY
or IN6ADDR_ANY is no longer supported. Switch to the loopback address
and simplify the code.
Note that (as the pre-existing comment in the code states) running
without a resolver configuration is not really supported. Still, if
we're going to have a hardcoded fallback, it might as well work.

newfs: Add an option to disable soft updates
A previous commit turned soft updates on by default for UFS2 without
providing a way to turn them off. This corrects that by adding a new -u
flag which forces soft updates (and soft updates journaling) off.

buf_ring: Rename some variables
The elements we store in buffer rings are buffers, so refer to them as
`buf` throughout instead of a mixture of `buf`, `ret`, and `new`,
especially since the latter breaks C++ code that directly or indirectly

expat: update to 2.7.4.
Release 2.7.4 Sat January 31 2026
Security fixes:
#1131 CVE-2026-24515 -- Function XML_ExternalEntityParserCreate
failed to copy the encoding handler data passed to
XML_SetUnknownEncodingHandler from the parent to the new
subparser. This can cause a NULL dereference (CWE-476) from
external entities that declare use of an unknown encoding.
The expected impact is denial of service. It takes use of
both functions XML_ExternalEntityParserCreate and
XML_SetUnknownEncodingHandler for an application to be
vulnerable.
#1075 CVE-2026-25210 -- Add missing check for integer overflow
related to buffer size determination in function doContent

#1073 lib: Fix missing undoing of group size expansion in doProlog
