The pacman --overwrite operation currently expects a path without
the root prefix specified. This is unexpected, particularly
given our conflict error message reports the path with the root
prefix included.
This patch allows libalpm to overwrite files with the root prefix
specified.

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

Attempting to compile pacman with gcc8 results in several warnings like:
remove.c: In function ‘unlink_file.isra.4’:
remove.c:407:34: warning: ‘.pacsave.’ directive output may be truncated writing 9 bytes into a region of size between 1 and 4096 [-Wformat-truncation=]
Fix by adding checks to error out if snprintf tries to reserve a
truncated filename. Because the return values are checked, gcc delegates
the truncation response to our code instead of throwing warnings.

pkg-config has built-in dependency handling, but we currently insert the

RFC 4880 defines two packet formats for OpenPGP. Pacman aborted its key
in keyring check with an error message if it encountered the new format.
This was fine until some annoying Arch Trusted User generated a key
using the new format!
Implement the new format. This also required parsing the hashed sub
packets. requiring the parsing code to moved to its own function.

Frontends rely on an initialization call for setup between downloads.
Checking for intialization after checking for a completed download can
skip initialization in cases where files are small enough to be
downloaded all at once (FS#56408). Relying on previous download size
can result in multiple initializations if there are multiple
non-transfer events prior to the download starting (fS#56468).
Introduce a new cb_initialized variable to the payload struct and use it
to ensure that the callback is initialized exactly once prior to any
actual events.

This is a rewrite of Tobias Stoeckmann’s patch from June 2016[1] using
functions instead of macros. (Thanks to Tobias for explanations of his patch.)
A short question on Freenode IRC showed that macros are generally discouraged
and functions should be used.
The patch introduces a static size_t length_check() in libalpm/signing.c.

This makes it possible to detect a failure in several alpm_list
functions. Previously these functions would continue after a failure,
returning partial results and potentially leaking memory.
Unfortunately, NULL is a valid return value for the affected functions
if the input list is empty, so they still do not have a dedicated error
value. Callers can at least detect an error by checking if the input
list was empty.

If a scriptlet/hook dies at the wrong moment it can trigger SIGPIPE,
terminating the process. For pipes, there is no way to prevent SIGPIPE
other than ignoring it process-wide. This can have unintended
consequences in a multi-threaded process. Using send(2) with sockets,
however, allows ignoring SIGPIPE on a per-call basis, leaving other
threads able to make use of SIGPIPE.

If the user replaces a directory with a symlink, libalpm would get
confused because the trailing slash causes system calls to resolve the
symlink. This leads to errors and a misleading message during upgrades.
Even though libalpm does not support this, it should not be giving
misleading errors.
Also adds an overflow check.
