It requires exposing 'move cursor to the end' function in a pacman
header file. We use it as a chance to make naming of the cursor management
functions more consistent.
Note that there is still possibility of a race condition in the cursor
update logic. 'update cursor index variable' and 'send ASCII control
symbols to console' is not an atomic operation. So if an SIGINT is
received between these two action then cursor position is going to be
screwed.

In commit c6b04c0465 the signing stage was
moved out of fakeroot, and thus into the main control flow instead of
create_{,src}package
While the function for signing binary packages has logic to build
and gpg-sign multiple filenames, the source package never got this
special treatment. This would be fine, except it uses the standard
variables to set define the filename... like ${fullver}, which is
usually set beforehand, but in this case is not. We don't define fullver
globally as it's an internal implementation detail, except by sheer
coincidence if PKGVERFUNC is false due to improperly guarded code.
Result: source packages didn't end up signed. Instead, we raised a logic
error:
==> WARNING: Failed to sign package file somepackage-.src.tar.gz.
==> ERROR: An unknown error has occurred. Exiting...
Instead, let's just build the version inline, since we only use it once.

If multiple files match the pattern libfoo.so*, we want to check each of
them and see if they are shared libraries, and if so, if they have
versions attached.
But some packages can have both shared libraries and random files which
match the filename pattern. This is true at least for files in
/usr/share/gdb/auto-load/, which must match the filename they are paired
with, followed by "-gdb.py" (or some other gdb scripting ext), but
definitely don't contain a shared library. In this case, we don't want
to double-report the library in the generated provides.
It's also possible (probably) for a package to provide a versioned as
well as an unversioned shared library, but in such cases a single
provides entry is sufficient to cover both cases (and the libdepends
for the depending package would contain an unversioned dependency).
Solve this by keeping track of whether we have added a versioned soname
provides already, and then only adding a maximum of one unversioned
provides *iff* there isn't a versioned one yet.

Pacman has multiple ways to verify package content integrity:
- gpg signature
- sha256
- md5
These verification mechanisms overlap each other. gpg signatures already contain
hash value of the package content. So if a package signature is present then
pacman ignored the other 2 hash values. This worked well with signtures
embedded into pacman database.
Recently pacman got an ability to handle detached signatures (*.sig files
located next to the package files). If pacman verifies detached signature only
then one can replace pkg+sig files with some other content and pacman still
processes it as a valid package. To prevent it we need to verify
database<->package integrity using hash values stored in the database.
This commit fixes FS#67232

Until now callee of ALPM download functionality has been in charge of
payload creation both for the main file (e.g. *.pkg) and for the accompanied
*.sig file. One advantage of such solution is that all payloads are
independent and can be fetched in parallel thus exploiting the maximum
level of download parallelism.
To build *.sig file url we've been using a simple string concatenation:
$requested_url + ".sig". Unfortunately there are cases when it does not
work. For example an archlinux.org "Download From Mirror" link looks like
this https://www.archlinux.org/packages/core/x86_64/bash/download/ and
it gets redirected to some mirror. But if we append ".sig" to the end of
the link url and try to download it then archlinux.org returns 404 error.
To overcome this issue we need to follow redirects for the main payload
first, find the final url and only then append '.sig' suffix.
This implies 2 things:
- the signature payload initialization need to be moved to dload.c
as it is the place where we have access to the resolved url
- *.sig is downloaded serially with the main payload and this reduces
level of parallelism
Move *.sig payload creation to dload.c. Once the main payload is fetched
successfully we check if the callee asked to download the accompanied
signature. If yes - create a new payload and add it to mcurl.
*.sig payload does not use server list of the main payload and thus does
not support mirror failover. *.sig file comes from the same server as
the main payload.
Refactor event loop in curl_multi_download_internal() a bit. Instead of
relying on curl_multi_check_finished_download() to return number of new
payloads we simply rerun the loop iteration one more time to check if
there are any active downloads left.

We pass this to gpg -u and this gpg option can accept a number of
different formats, not just the historical hexadecimal fingerprint we
assumed. We should not barf hard if a format is used which happens to
contain spaces.
This also fixes a validation bug. When we initially check if the desired
key is available, we don't quote spaces, so gpg goes ahead and treats
each space-separated string as a *different key* to search for,
returning partial matches, and returning success if at least one key is
found. But gpg --detach-sign -u will certainly not accept multiple keys!

In commit 882e707e40 we changed message
output to go to stdout by default, unless it was an error. The plain()
function doesn't *look* like an error function, but in practice it was
-- it's used to continue multiline messages, and all in-tree uses were
for warning/error.
This is a problem both because we're sending output to the wrong place,
and because in some cases, we were performing error logging from a
function which would otherwise return a value to be captured in a
variable using command substution.
Fix this and straighten out the API by providing two functions: one for
continuing msg output, and one which wraps this by sending output to
stderr, for continuing error output.
Change all callers to use the second function.
This was broken in commit 882e707e40,
which changed 'plain()' messages to go to stdout, which was then
captured as the download client in question: cmdline=("Aborting...").
The result was a very confusing error message e.g.
/usr/share/makepkg/source/file.sh: line 72: $'\E[1m': command not found
or with makepkg --nocolor:
/usr/share/makepkg/source/file.sh: line 72: Aborting...: command not found
The problem here is that we checked to see if an asynchronous subshell,
in our case <(...), failed, by checking if its captured stdout is
non-empty. Which is terrible, and also a limitation of old bash. But
bash 4.4 can use wait $! to retrieve the return value of an asynchronous
subshell. Now we target that as our minimum, we can sanely handle errors
in such functions.
Losing error messages on stdout by capturing them in a variable instead
of printing them, continues to be a problem, but this will be fixed
systematically in a later commit.
