Extend the 16-bit PCI bus:dev.fn address to a 32-bit seg🚌dev.fn
address, assuming a segment value of zero in contexts where multiple
segments are unsupported by the underlying data structures (e.g. in
the iBFT or BOFM tables).

Commit 09b057c ("[settings] Remove "uristring" setting type") removed
support for URI-encoded settings via the "uristring" setting type, on
the basis that such encoding was no longer necessary to avoid problems
with the command line parser.
Other valid use cases for the "uristring" setting type do exist: for
example, a password containing a '/' character expanded via
chain http://username:${password:uristring}@server.name/boot.php
Restore the existence of the "uristring" setting, avoiding the
potentially large stack allocations that were used in the old code
prior to commit 09b057c ("[settings] Remove "uristring" setting
type").

The settings self-tests include tests for the "ipv6" setting type.
When IPv6 support is not included, this setting type exists (since it
is referred to by some dual-stack code, such as dns.c) but is
non-functional.
Force IPv6 support to be included within a settings self-test build
using an explicit REQUIRE_OBJECT() macro.

Commit b5f5f73 ("[cmdline] Expand settings within each command-line
token individually") effectively rendered the "uristring" setting type
obsolete, since strings containing whitespace no longer break the
command line parser. The concept of the "uristring" type is not well
defined, since URI escaping rules depend on which portion of a URI is
being escaped.
Remove the "uristring" type, converting it into an alias for the
"string" setting type so as to avoid breaking existing scripts.

The fetch_setting() family of functions may currently modify the
definition of the specified setting (e.g. to add missing type
information). Clean up this interface by requiring callers to provide
an explicit buffer to contain the completed definition of the fetched
setting, if required.

Allow numeric_setting_value() to handle e.g. the byte sequence
00:00:00:00:12:34:56:78
by returning -ERANGE only if the value actually overflows the return
type.

Allow network device's "busloc" setting to be formatted as a PCI
bus:dev.fn address using e.g. ${net0/busloc:busdevfn}.

Use hex_decode() to parse "hex" and "hexhyp" settings. Note that this
parser is stricter than the old parser; it now requires exactly two
hex digits for each byte. (The old parser was based upon strtoul()
and so would allow leading whitespace and a leading plus or minus
sign.)

Commit 5ad445f ("[settings] Treat an empty formatted value as meaning
"delete setting"") (re)defined the semantics of storing an empty
formatted setting as meaning "delete setting".
Remove the existing self-test using an empty formatted hex setting
value, since it no longer conforms to the defined semantics.
