libfetch: Pass a zeroed digest to DigestCalcResponse.

GCC 12 warns that passing "" (a constant of char[1]) to a parameter of
type char[33] could potentially overread. It is not clear from the
context that c->qops can never be "auth-int" (and if it can't, then
the "auth-int" handling in DigestCalcResponse is dead code that should
be removed since this is the only place the function is called).

When deciding whether to send the complete URL or just the document part,
we were looking at the original URL rather than the one we were currently
processing. This meant that if we were trying to retrieve an HTTP URL but
were redirected to an HTTPS URL, and HTTPS proxying was enabled, we would
send an invalid request and most likely get garbage back.

lib: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

r308996 broke IP literals by assuming that a colon could only occur as

r308996 broke IP literals by assuming that a colon could only occur as
a separator between host and port, and using strchr() to search for it.
Rewrite fetch_resolve() so it handles bracketed literals correctly, and
remove similar code elsewhere to avoid passing unbracketed literals to
fetch_resolve(). Remove #ifdef INET6 so we still parse IP literals
correctly even if we do not have the ability to connect to them.

While there, fix an off-by-one error which caused HTTP 400 errors to be
misinterpreted as redirects.

Fix partial requests (used by fetch -r) when the requested file is
already complete.

Since 416 is an error code, any Content-Range header in the response
would refer to the error message, not the requested document, so
relying on the value of size when we know we got a 416 is wrong.
Instead, just verify that offset == 0 and assume that we've reached
the end of the document (if offset > 0, we did not request a range,
and the server is screwing with us). Note that we cannot distinguish
between reaching the end and going past it, but that is a flaw in the
protocol, not in the code, so we just have to assume that the caller
knows what it's doing. A smart caller would request an offset
slightly before what it believes is the end and compare the result to
what is already in the file.

Use strlcpy() instead of strncpy() to copy the string returned by
setlocale() so that static analyzers know that the string is NUL
terminated. This was causing a false positive in Coverity even
though the longest string returned by setlocale() is ENCODING_LEN
(31) and we are copying into a 64 byte buffer. This change is also
a bit of an optimization since we don't need the strncpy() feature
of padding the rest of the destination buffer with NUL characters.
