Parsing pacman's configuration file is non-trivial and extremely
difficult to do correctly from scripts; even our own do it incorrectly.
pacman-conf is a dedicated tool specifically to allow scripts to parse
config files, getting the same value that pacman itself would use.

Default values for configuration settings were being set during alpm
setup and in some cases were never saved back to the original config
struct. Refactoring all default settings into a separate function and
saving them onto the original config struct will allow pacman-conf to
resolve the defaults without having to setup alpm.

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.

Commit 8bec63bf92d8dd028aa88dbd5109c314cdb9ebea attempted to switch to
using -fdebug-prefix-map to set file locations in debug packages. It
make a few mistakes...
1) Adding debug C{,XX}FLAGS only worked if DBGSRCDIR was defined in
makepkg.conf. Fix this by falling back to the default value.
2) Using -fdebug-prefix-map altered a lot of assumptions about file
locations when copying source files into debug packages. This resulted
in lots of messages of failed cp in packaging output.

If you manage to download a bad database (e.g. an html file when

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.

In eaa82b4d0775252856a4e54a6f2a9ea191cf0b8f source_has_signature() was
modified to check if git repositories are marked as signed. However, due
to a typo the unused variable $netfile was checked. This worked as long
as the last source element was marked as signed, due to $netfile being
mistakenly set as a global in check_vcs_software(), but usually failed
with multiple sources.
Break this more consistently by properly declaring $netfile as a local
variable in check_vcs_software() which it should be regardless. Fix it
again by completely moving over to $netfile in source_has_signature()
as netfile is more descriptive of the current state.

In 42e7020281d3ae260e1e9693495f527b7f476625 creating the gpg statusfile
for a source file was split into a separate function, which used the
return code to indicate unsigned files and proto-specific errors.
However, the fallback return code was set by the final gpg invocation,
which would be 1 if the signature was somehow broken (for example, the
key was not available in the gpg keyring). As a result makepkg thought
that file did not have a signature and skipped over it rather than
erroring out.
Fix this by explicitly setting the return code for all
verify_*_signature() functions.

In commit 8b0d59b83a60eb504567590346119fe4cd891cad support was added for
storing the source files of binaries in debug packages. This made use of
the debugedit program which is part of the RPM package manager, which is
not very standalone.
The same effect can be achieved using -fdebug-prefix-map, an option
accepted by both the gcc and clang compilers which modifies how the
compiler itself stores the references to the source files rather than
requiring us to later edit the produced binaries. This also removes the
dependency on external programs like debugedit.
As a result of this change, source files will only be effectively added
for programs which actually use the exported CFLAGS. This is a reasonable
tradeoff as we expect our CFLAGS to be used rather than ignored. Upstream
software which do not produce useful debug packages are expected to fix
their build systems to respect the environment CFLAGS.
As a result of this change, the routine for extracting source filenames
from binaries had to be modified to derive the source file from the
final debug location, rather than the other way around.

This allows for more easily extending the list of allowed compression
methods, as it has to be modified in only one place.
Also allow the user to specify their own preferred command + options for
source packages in addition to compiled packages. Currently,
makepkg.conf(5) erroneously claims this is already possible.

Prior to commit aca153bfa6b1bcd828f0b35db453bb9fea6a08bf some .sh files
were not generated and simply included directly, and it was necessary to
explicitly iterate all ignored files to prevent git from ignoring the
directly-included files. However, now all .sh files are in fact
generated so it makes no sense to list each one separately in the
.gitignore file.

The extra variables on the commandline were inconsistently applied. They
should override anything else, instead, most were overridden by
environment variables with the exception of BUILDDIR (and this was not
sanity-checked to see if it had write permissions).
e.g. given the commandline:
`PKGDEST="$(pwd)"` BUILDDIR="$(pwd)" makepkg PKGDEST=/doesnt/exist BUILDDIR=/doesnt/exist`
We would incorrectly use the current working directory for PKGDEST.
Meanwhile, we checked the wrong directory for BUILDDIR, and later
errored when we tried to create $srcdir inside the non-writable
directory "/doesnt/exist".
In order to fix this, use the preferred bash builtin for saving variable
definitions, similar to how we restore traps etc. rather than tediously
redefining each one by hand, and restore this immediately after
makepkg.conf is sourced. Finally, the `make`-style commandline overrides
are applied.
Also canonicalize_path is applied only on the final paths we try to use.
While it is unlikely the value in makepkg.conf will be a relative path,
since we now properly respect commandline overrides, they should be
canonicalized as well.

functions instead of macros. (Thanks to Tobias for explanations of his patch.)

The documentation for OPTIONS and BUILDENV listed some incorrect
defaults for undefined options. The defaults are implementation-defined
in the source code for makepkg itself (e.g. it depends whether we use
`check_option "opt" "y"` or `check_option "opt" "n"`) but were
erroneously declared to be "whatever we *define* in the default
makepkg.conf".

As per https://lists.archlinux.org/pipermail/arch-general/2017-July/043876.html
git doesn't check that the tag name matches what an annotated tag object
*thinks* it should be called. This is a bit of a theoretical attack and
some would argue that we should always use commits since upstream can
legitimately change a tag, but nevertheless this can result in a
downgrade attack if the git download transport was manipulated or the
upstream repository hacked.
So, check the tag blob to make sure the tag actually matches the name we
used for `git checkout`.
This really should be fixed in git itself, rather than forcing all
downstream users of git verify-tag to implement their own checks, but
the git developers disagree, see the discussion surrounding

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.

This patch introduces the SOURCE_DATE_EPOCH environmental variable. All files
in a package are adjusted to have their modification dates set to the value
of SOURCE_DATE_EPOCH, which defaults to "date +%s".
Setting this variable allows a package that is built twice in the same
environment to be (potentially) reproducible in that the checksum of the
generated package file will be the same.
Also adjust the compression of the mtree file to avoid gzip embedding a
timestamp.
