This should replace most InputStream::Open() calls because it is a
chance to reuse existing resources (e.g. the NFS connection). No such
optimization is implemented, currently (and the method is not yet used
by anybody).
According to the latest WebDAV specification (RFC4918),
timestamp string in the getlastmodified property is formatted
as rfc1123-date, such as "Sun, 06 Nov 1994 08:49:37 GMT".
However, to process responses from servers in the older style
format specified in RFC2518, timestamps in the HTTP-date format
had better be accepted.
As described in the libcurl api documentation, curl_getdate() can handle
timestamp strings in HTTP-date formats, including rfc1123-date.

SonarLint reports the latter to be better:
std::scoped_lock basically provides the same feature as std::lock_guard,
but is more generic: It can lock several mutexes at the same time, with a
deadlock prevention mechanism (see {rule:cpp:S5524}). The equivalent code
to perform simultaneous locking with std::lock_guard is significantly more
complex. Therefore, it is simpler to use std::scoped_lock all the time,
even when locking only one mutex (there will be no performance impact).

With the default value CURLAUTH_ANY, libcurl needs to probe for
authentication methods first, and only the second request will have an
Authorization header.

ParseTimePoint.
%Z is a glibc extension to strptime, and is a no-op there, due to the
mapping between timezone names and their definition (especially when the
name comes from a different machine) being ambiguous / impossible. Time
in HTTP headers is guaranteed to be UTC.
Passing an unknown format to strptime() implementations that don't
support it will generally cause them to return NULL, which will lead to
ParseTimePoint throwing an exception and ParseTimeStamp using an
unnecessary fallback.
Since the timezone name goes at the end of the string, we don't need to
use %Z to skip it (could be an issue in a different time stamp format),
so simply removing %Z works best.
The original base relative path was introduced due to an erroneous test
where the URL started with three slashes: "https:///" instead of two,
which led to implementing handling for such cases but broke the two
slashes case.
This fix removes the base relative path handling because with two
slashes the path is anyway always relative to the host (aka absolute
URI, without host).

Use uri_has_scheme to find out if the href in Webdav responses is absolute
to use the matching base path extraction.

There can be more than one propstat block each with their own status
code. We're only interested in the one with the 200 status, the found
properties.
This fixes parsing to make sure we process all propstat blocks instead
of just the last one, which might have a 404 status for not-found
properties.

Pass a std::string to PathTraitsUTF8::Relative(), implicitly casting
it to std::string_view. This selects the right overload which returns
std::string_view instead of `const char *`; the latter could return
`nullptr` which would cause the implicit conversion of the return
value to std::string_view to crash.
Regression caused by commits ead208987d and a98d627c0b.

Unescape the base path and the path coming from the server (href) to fix the
comparison when the server uses different escaped characters.
The outputted name need to be unescaped. Doing that before or after the
HrefToEscapedName() call should not change the current behavior.
If the file name is "Hello & bye", 3 CharacterData events will be sent with the
State::HREF state:
- "Hello%20"
- "&"
- "%20bye"
Reproduced with files hosted on an apache2 DAV server: 2.4.38-3+deb10u3.
