We should not need to hardcode the path to sed as we simply don't care.
We don't check what kind of sed we found, and we're using the same one
we initially found on the PATH, which is surely still on the PATH.
At one point we did care to find the system copy of sed and hardcode it
in makepkg, because we also passed non-portable -i options to it and
makepkg needed to continue working on macOS even if some incompatible
GNU sed got installed afterward, elsewhere on the PATH. But this was
never relevant to the in-tree buildsystem script running sed.
In commit 3a814ee6bc we removed even that,
so we don't need to look it up at all.

All the required public API is annotated with SYMEXPORT, so we can just
add the meson notation, to hide all the symbols by default.
Thus we no longer spill all the internal API into the global namespace.
This is effectively a regression from the autotools build, which used
hidden and internal for DARWIN and others respectively.
The use of hidden is considered sufficient, considering:
- internal was introduced with commit 920b0d20 ("Update usage of gcc
__attribute__ flags"), referencing the GCC manual and potential
optimisations, although
- the details about the optimisations or respective benefits are close
to non-existent,
- the code/data size of the binaries is identical across hidden and
internal. While the latter produces slightly larger overall binaries.
- Internal is not widely supported - missing on Darwin, the CMake build
system lacks a wrapper (unlike for hidden)
- Internal is not widely used in projects.

Currently, we are erroneously exporting all the symbols via the

The libalpm.so exports are about to be resolved shortly, yet that

In order to use gettext on systems where it is not part of libc, the
correct linker flags are needed in libalpm.pc (for static compilation).
This has never been the case.
The new meson build system currently only checks for ngettext in libc,
but does not fall back to searching for the existence of -lintl; add it
to the libalpm dependencies.

meson 0.48 added the 'debug' and 'optimization' builtin options, which
bidirectionally map to the buildtype, but in some cases where debug is
enabled, the builtype may be custom. Checking the 'debug' option lets us
detect every case currently detected, plus a few more, and does so in a
shorter and more concise manner.

In addition to the general issue of staticlibs linkage, linking a static
lib to a library() does not seem to generate the needed Libs.private.
Rework how we handle this entirely. Instead of relying on convenience
libraries, we will *sigh* go extract a boatload of .o files again, then
relink those to the installable libalpm, while mentioning our
dependencies again.
We still have our guaranteed static library for linking arbitrary programs
with (e.g. vercmp), and we still only generate one identical copy of the
.o files, but now we potentially `ar` it up twice, which isn't so bad.
And linking still works, and pkg-config files also still work.
One alternative would be to explicitly list our dependencies to
pkgconfig.generate with requires_private, but since gpgme might be an
elevated config-tool dependency, this can fail with:
meson.build:341:10: ERROR: requires argument not a string, library with pkgconfig-generated file or pkgconfig-dependency object, got <GpgmeDependency gpgme: True>

Not all compression types can be detected in the seccomp sandbox, so we
need to disable it. This requires either configuring makepkg to know the
sandbox is available, or checking for file >= 5.38 in which the sandbox
option is a no-op even when seccomp is disabled.

- meson version comparison could be made a lot simpler using meson-git.

The default state of `dependency()` is `required: true`, which means if
a dependency is not found, meson immediately aborts and does not log our

The libarchive header is used in alpm.h, and several binaries include
this header. This is noticeably a problem when using e.g. the musl-gcc
compiler which does not include /usr/include by default, and thus the
build system reports:
...../lib/libalpm/alpm.h:35:10: fatal error: archive.h: No such file or directory
More commonly, this will result in compiling against potentially the
wrong headers, if the libarchive installation picked up by pkg-config is
different from the one with headers in /usr/include, and /usr/include is
in the -isystem path.

This has historically been the case in autotools since we want vercmp to
not break mid-transaction in an install script.
For convenience, we create libalpm.a and use this to optionally generate
libalpm.so (when not configured with -Dbuildstatic=true) as well as to
link any binary which explicitly wishes to be built statically "with
libalpm", but does not care where a function is defined. meson then
treats this correctly: it builds the object file only once for both
libraries, and the compiler strips out unused functionality from the
final static binary.
Currently the only binary which requires this is vercmp.

This matches what we currently do in the autotools build configuration,
and ensures that the default pacman-conf definitions for unspecified
values consistently end with the trailing directory slashes.
This has ramifications for thirdparty tools that up to now, have relied
on this slash being there. Those tools should be fixed to prevent
breaking when custom locations are set, but this is no reason not to fix
it on our end as well. An extra trailng slash should never cause harm.

This doesn't do quite as good of a job of "hiding away" the real script
as we did with autotools, but it satisfies the need for being able to
run scripts which depend on libmakepkg with the local copy within the
repo. We do, however, improve upon the autotools script by ensuring that
the bash path used in configuring pacman is the interpreter used to run
the underlying script.
Provide both build systems in parallel for now, to ensure that we work
out all the differences between the two. Some time from now, we'll give
up on autotools.
Meson tends to be faster and probably easier to read/maintain. On my
machine, the full meson configure+build+install takes a little under
half as long as a similar autotools-based invocation.
Building with meson is a two step process. First, configure the build:
meson build
Then, compile the project:
ninja -C build
There's some mild differences in functionality between meson and
autotools. specifically:
1) No singular update-po target. meson only generates individual
update-po targets for each textdomain (of which we have 3). To make
this easier, there's a build-aux/update-po script which finds all
update-po targets and runs them.
2) No 'make dist' equivalent. Just run 'git archive' to generate a
suitable tarball for distribution.
