1c4e079899 do not try to download an empty db list
Starting the download process, even if there is nothing to actually
download, causes an error when pacman is built without curl and has no
XferCommand defined (like our test suite).

027d76b9f5 libalpm: introduce get_sync_pkg_ops() helper
Currently default_pkg_ops is accessed in two different ways.

There is get_file_pkg_ops (in be_package.c) creating a local once-off
'tweaked' copy. As well as load_pkg_for_entry (be_sync.c) which modifies
in-place and uses default_pkg_ops.

This seems rather misleading and fragile approach. Introduce a helper
for the second use-case so that default_pkg_ops is handled consistently
and essentially remains unchanged throughout.

f078c2d3bc Move signature payload creation to download engine
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.

b96e0df4dc Implement multibar UI
Multiplexed download requires ability to draw UI for multiple active progress
bars. To implement it we use ANSI codes to move cursor up/down and then
redraw the required progress bar.
`pacman_multibar_ui.active_downloads` field represents the list of active
downloads that correspond to progress bars.
`struct pacman_progress_bar` is a data structure for a progress bar.

In some cases (e.g. database downloads) we want to keep progress bars in order.
In some other cases (package downloads) we want to move completed items to the
top of the screen. Function `multibar_move_completed_up` allows to configure
such behavior.

Per discussion in the maillist we do not want to show download progress for
signature files.

64c4669f57 Introduce event types for start/end database list download
Multiplexed database/files downloads will use multiple progress bars.
The UI logic is quite complicated and printing error messages while
handling multiple progress bars is going to be challenging.

Instead we are going to save all ALPM error messages to a list and flush
it at the end of the download process. Use on_progress variable that
blocks error messages printing.

a8a1a1bb3e Introduce alpm_dbs_update() function for parallel db updates
This is an equivalent of alpm_db_update but for multiplexed (parallel)
download. The difference is that this function accepts list of
databases to update. And then ALPM internals download it in parallel if
possible.

Add a stub for _alpm_multi_download the function that will do parallel
payloads downloads in the future.

Introduce dload_payload->filepath field that contains url path to the
file we download. It is like fileurl field but does not contain
protocol/server part. The rationale for having this field is that with
the curl multidownload the server retry logic is going to move to a curl
callback. And the callback needs to be able to reconstruct the 'next'
fileurl. One will be able to do it by getting the next server url from
'servers' list and then concat with filepath. Once the 'parallel download'
refactoring is over 'fileurl' field will go away.

1b32897453 Add REALLOC macro to simplify realloc error handling
realloc can fail just like the other memory allocation functions. Add a
macro to simplify handling of realloc failures, similar to the already
existing MALLOC, CALLOC, etc.

Replace the existing realloc uses with the new macro, allowing us to
move tedious error handling to the macro. Also, in be_package and
be_sync, this fixes hypothetical memory leaks (and thereafter null
pointer dereferences) in case realloc fails to shrink the allocated
memory.

860e4c4943 Remove all modelines from the project
Many of these are pointless (e.g. there is no need to explicitly turn on
spellchecking and language dictionaries for the manpages by default).

The only useful modelines are the ones enforcing the project coding
standards for indentation style (and "maybe" filetype/syntax, but
everything except the asciidoc manpages and makepkg.conf is already
autodetected), and indent style can be applied more easily with
.editorconfig

8ee084dbb3 db_update: always clear db flags after update
Signature downloading and DB validation was being based on the most
recent download status for the DB.  If a DB successfully downloaded but
a signature did not, db_update would move to the next server.  If the
next server tried does not have a more recent copy of the DB, db_update
would not download the DB again and would forget that the DB had
previously been updated.  In this case it would skip validation
entirely, leaving an updated DB with the original validation status.

5780350751 libalpm: Force update when database is marked as corrupted.
When a database and its signature is updated non-atomically on a server,
there is a window where a user may update the database but grab the old
signature.  The database is marked as invalid by libalpm, which can be
fixed by forcing a refresh (assuming the server has caught up and the
user realizes what has happened) or with a future update of the repo.
Work around this by forcing a repository refresh whenever a database is
