Previously, -libssh2/-rtmp options assumed that OpenSSL is also enabled
(and then failed with an error when not finding expected OpenSSL headers),
but this isn't necessarly true, e.g. when building both libssh2 and curl
against Schannel. This patch makes sure to only enable the OpenSSL backend
with -libssh2/-rtmp, when there was no SSL option explicitly selected.
- Re-implement the logic as a single block of script.
- Also fix an indentation while there.

The signal handler registered for SIGINT is only handling SIGINT
so there isn't much need for inspecting the signo. While there,
rename the handler to be more specific.
g_should_exit should really be of sig_atomic_t type, but relying

time_t representation is undefined and varies on bitsize and signedness,
and as of C11 could be even non integer.
instead of casting to unsigned long (which would truncate in systems
with a 32bit long after 2106) use difftime to get the elapsed time as a
double and print that (without decimals) instead.
alternatively a cast to curl_off_t and its corresponding print
formatting could have been used (at least in POSIX) but portability and
curl agnostic code was prioritized.

The API is soon two years old and deserves being shown as the primary

It should not assume that it can copy full lines into the buffer as it
will encourage sloppy coding practices. Instead use byte-wise logic and

Warning: this will make existing curl command lines that use metalink to
stop working.
Reasons for removal:
1. We've found several security problems and issues involving the
metalink support in curl. The issues are not detailed here. When
working on those, it become apparent to the team that several of the
problems are due to the system design, metalink library API and what
the metalink RFC says. They are very hard to fix on the curl side
only.
2. The metalink usage with curl was only very briefly documented and was
not following the "normal" curl usage pattern in several ways, making
it surprising and non-intuitive which could lead to further security
issues.
3. The metalink library was last updated 6 years ago and wasn't so
active the years before that either. An unmaintained library means
there's a security problem waiting to happen. This is probably reason
enough.
4. Metalink requires an XML parsing library, which is complex code (even
the smaller alternatives) and to this day often gets security
updates.
5. Metalink is not a widely used curl feature. In the 2020 curl user
survey, only 1.4% of the responders said that they'd are using it. In
2021 that number was 1.2%. Searching the web also show very few
traces of it being used, even with other tools.
6. The torrent format and associated technology clearly won for
downloading large files from multiple sources in parallel.

If `index.html` does not exist in the directory from which the example
is invoked, the fopen(upload, "rb") invocation in `setup` would fail,
returning NULL. This value is subsequently passed as the FILE* argument
of the `fread` invocation in the `read_callback` function, which is the
actual cause of the crash (apparently `fread` assumes that argument to
be non-null).
In addition, mitigate some possible crashes of similar origin.
