app-portage/prefix-toolkit: new package

* For any Gentoo Prefix, provides the 'startprefix' script, and should
provide some 'runprefix' script later on, as inspired in
Bug: https://bugs.gentoo.org/673816

* For base Gentoo Prefix (as in "not stacked"), provides the
'prefix-stack-setup' script, superseding app-portage/prefix-chain-setup,
does force the prefix-stack implit USE flag in the stacked Prefix.
* For stacked Gentoo Prefix (set up using 'prefix-stack-setup'),
provides the toolchain wrapper, superseding sys-apps/prefix-chain-utils.
Bug: https://bugs.gentoo.org/658572

Closes: https://bugs.gentoo.org/509142

app-portage/prefix-toolkit: add keywords where prefix may go

As bootstrap-prefix.sh now does emerge prefix-toolkit, it requires any
keyword wherever Prefix may go - including RAP with non-Prefix keywords.

app-portage/prefix-toolkit: revbump

* In prefix-stack, maintain @system set independent of profile, as in
explicitly removing everything found per etc/portage/make.profile, but
adding prefix-toolkit, having RDEPENDs for additional @system packages.
* Do not install libtool into prefix-stack any more, packages really
should not use any installed libtool script, but configure their own.
* In prefix-stack toolchain on Linux, use -isystem to avoid warnings
from installed header files.  Remember: This is known to break on AIX.

Package-Manager: Portage-2.3.67-prefix, Repoman-2.3.13

app-portage/prefix-toolkit (prefix-stack-setup): revbump

We do not want to have CBUILD build deps in prefix-stack, but CHOST
build deps only.  Since EAPI 7 there is BDEPEND, but EAPI 6 and older
have both CBUILD and CHOST build deps in DEPEND.  As most CHOST build
deps also are in RDEPEND anyway, we omit EAPI 6 DEPEND from prefix-stack
by setting EMERGE_DEFAULT_OPTS="--root-deps=rdeps" - ignored for EAPI 7.

Package-Manager: Portage-2.3.66, Repoman-2.3.11

app-portage/prefix-toolkit: revbump

startprefix:
* On Cygwin (assumed when /proc/registry/ is available), also preserve
SYSTEMDRIVE, COMSPEC and TEMP env vars, for native Windows programs.

prefix-stack-setup:
* Give the child prefix a private PORTAGE_TMPDIR, to not lock
PORTAGE_TMPDIR in base prefix when merging in multiple childs.
* Define clean CFLAGS/CXXFLAGS for the child prefix, it may use a
different compiler.  Instead, preserve the base prefix' CFLAGS/CXXFLAGS
via package.env only for packages using the base prefix compiler.

Package-Manager: Portage-2.3.69, Repoman-2.3.16

app-portage/prefix-toolkit(winnt): pull pthreads4w, intercept -pthread

Some X11 library build system is dumb enough to just use -pthread,
while others do triage this, before trying with -lpthread.  So we
intercept the -pthread compiler flag and add -lpthread instead.
We cannot do that in parity because pthreads4w is installed in the
stacked prefix, where it is built using parity.

app-portage/prefix-toolkit: stack: set AT_SYS_M4DIR, run gcc-config

In stacked Prefix, need to set AT_SYS_M4DIR so eautoreconf is able to
find the m4 files from stacked Prefix.
As prefix-toolkit does wrap the compiler found in base prefix to get the
additional system paths in, need to perform gcc-config at pkg_postinst.

app-portage/prefix-toolkit: startprefix is for Prefix only

To allow for prefix-stack on top of vanilla Gentoo, prefix-stack-setup
does make sense there - but startprefix does not.
Add comment why prefix-stack does have some RDEPENDs, and reorder
RDEPEND to logically match the comment.

app-portage/prefix-toolkit: keyword ~arm64-macos.

Currently, Gentoo Prefix cannot be started on macOS w/ Apple Silicon
due to the missing ~arm64-macos in app-portage/prefix-toolkit, which
contains the script "startprefix". Adding the keyword allows the
prefix to start.

app-portage/prefix-toolkit: drop crime-against-ebuild (don't self-extract files)

I've tried my best at a faithful conversion at https://gitweb.gentoo.org/proj/prefix/prefix-toolkit.git/
with the ebuilds, extracted contents from them, and original commit authorship & messages
(w/ cherry-picked reference to ::gentoo commits).

There's also a 'naive-conversion' branch with just me doing the extraction.

Closes: https://bugs.gentoo.org/866962

app-portage/prefix-toolkit: add 10, drop 9
