d55924dbd7 debugflags: Ensure we have unique source paths
In some cases packages are built outside of a directory which contains
pkgname-pkgver, this results in source listing in debug packages having
a conflicting path like `/usr/src/debug/build/` which is not ideal.

This patch ensures we always include the pkgbase to ensure the paths are
unique.

ce40629b7d libmakepkg: Do not "strip" files when the format is not recognised
We use a multi step process during stripping to ensure permissions do
not get changed.  However, if the initial objcopy fails, the subsequent cat
results in a blank file.  Abandon early if objcopy fails.

51354b7da9 Make link time optimization flags configurable
We want to use -flto=auto in Arch Linux to speed up building, but we
can't hardcode it in buildenv/lto.sh because other downstreams might
have clang < 13.0.0 which did not recognize -flto=auto as equivalent
to -flto=full.

Introducing an LTOFLAGS variable to makepkg.conf seems the way to go.

c4a21f333a strip: Use debugedit instead of AWK to parse source files
This moves us from the fairly ugly AWK parsing line to debugedit which
originally comes out of the rpm project.

The original code has issues parsing anything that was not straight
C/C++ and languages like Rust or Go would return invalid source code
files. debugedit handles all these cases better.

95ef989978 makepkg: use -ffile-prefix-map instead of -fdebug-prefix-map
>From gcc(1):

-ffile-prefix-map=old=new
	[...] Specifying this option is equivalent to specifying all the
	individual -f*-prefix-map options. This can be used to make reproducible
	builds that are location independent.

Specifically, this additionally enables -fmacro-prefix-map=, which causes
prefix mapping to be applied to expansions of __FILE__ and similar macros.

Without this option, if source files are compiled by passing the
absolute file path to the compiler (as done by e.g. cmake), any
expansions of __FILE__ (e.g. from uses of assert()) will contain
$srcdir.

e176b8ec19 makepkg: squelch readelf warnings from debug stripping
readelf --debug-dump sometimes reports inscrutable warnings which don't
actually affect our extraction of source filenames. For example:

readelf: Warning: There is a hole [0xd3d - 0xd89] in .debug_loc section.

Now gcc 11 seems to have dramatically increased the number of warnings:

readelf: Warning: Corrupt offset (0x0000008e) in range entry 9
[...]
readelf: Warning: Corrupt offset (0x000010f0) in range entry 250

The resulting debuginfo created by the very same toolchain works fine,
as does the list of source filenames. But the warnings are quite
noisy... send them to /dev/null since they are not actionable in the
context of getting source files

bdf6aa3fb7 libmakepkg: fix detection of source file names for debug packages

readelf:

gcc-10.2.0
$ readelf "hello" --debug-dump | grep hello

gcc-git
$ readelf "hello" --debug-dump | grep hello
<12> DW_AT_name : (indirect line string, offset: 0x0): hello.cpp

This causes the awk statement extracting the file name to fail as it
relied on the information being in the 8th field. Instead, extract
the information from the final field.

88d054093c makepkg: don't let the strip routine mess up file attributes
It updates the stripped/objcopied file by creating a temp file,
chown/chmodding it, and replacing the original file. But upstream
binutils has CVE-worthy issues with this if running strip as root, and
some recent versions of strip don't play nicely with fakeroot.

Also, this has always destroyed xattrs. :/

Sidestep the issue by telling strip/objcopy to write to a temporary
file, and manually dump the contents of that back into the original
binary. Since the original binary is intact, albeit with different
contents, it retains its correct attributes in fakeroot.

6b9c1b4d54 srcinfo.sh: remove trailing newline
When a .SRCINFO file is generated via `makepkg --printsrcinfo`, each
section is concluded with an empty line. This means that at the end of
the file, an empty line remains. This is considered a trailing
whitespace error. In fact, `git diff --check` will warn about this,
saying "new blank line at EOF."

Instead of closing each section off with an empty line, use the empty
line to separate sections, omitting the empty line at the end of the
file.

899d39b635 makepkg/repo-add: handle GPGKEY with spaces
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!

bf458cced7 libmakepkg: fix regression in sending plain() output to stderr
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.

381e113755 makepkg: correctly handle missing download clients
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.

d626a17ef9 makepkg: make per-package files containing '$pkgname' consistently work
Extracting function variables containing arbitrarily scoped variables of
arbitrary nature is a disaster, but let's at least cover the common case
of using the actual '$pkgname' in an install/changelog file. It's the
odd case of actually being basically justified use of disambiguating
between the same variable used in multiple different split packages...
and also, --printsrcinfo already uses and overwrites the variable
'pkgname' in pkgbuild_extract_to_srcinfo, so this "works" in .SRCINFO
but doesn't work in .src.tar.gz

It doesn't work in lint_pkgbuild either, but in that case the problem is
being too permissive, not too restrictive -- we might end up checking
the same file twice, and printing that it is missing twice.

349c22d043 makepkg: fix regression that broke extraction of file:// sources
In commit 9c817b6549 we made these sources
extendable, and heuristically determined the correct extraction
functions to use. But our fallback for protos that didn't have an exact
extract_* function didn't take into account that 'extract_file' matches
an actual proto... so we passed the netfile in while the function
expected a file.

Solution: the function should expect a netfile too, thereby allowing us
to delay an attempted resolution of netfile -> file, to the one case
where it is actually used. This makes us slightly more efficient in the
non-file case, makes our functions a bit more consistent, and makes
file:// extraction work again.

55a65aaf90 makepkg: restrict pkgname and pkgver to ascii
pkgname and pkgver are used as directory names within database files.
libarchive does not provide a reliable locale-independent method for
reading archive file names, causing errors when archive paths include
non-ascii characters.

This is a first step toward dealing with FS#49342, by hopefully reducing
the number of packages with non-ascii data in the wild before updating
libalpm to reject them outright.

See https://github.com/libarchive/libarchive/wiki/Filenames
and https://github.com/libarchive/libarchive/issues/587

a00615bfda makepkg: move config loading into libmakepkg
When scripting/automating around makepkg, it is sometimes desirable to
know how makepkg will be configured to operate. One example is the
archlinux devtools, which must forward select makepkg.conf variables
into a build chroot (for example PACKAGER) or use those variables itself
(for example {SRC,PKG,LOG}DEST).

The configuration file can be in up to 3 places, and should be capable
of being overridden via environment variables. It is sufficiently
complex to represent distinct functionality, and sufficiently useful to
merit easy accessibility in other scripts, therefore, let us move it
into a publicly exposed utility library.
