dmd.eclass: Support >=dmd-2.101

Since dmd-2.101 the dmd and druntime upstream repositories have merged
and paths need to be adjusted.

The download link needs to be changed as well as new releases are no
longer uploaded to aws.

dlang.eclass: Support DLANG_COMPILER_DISABLED_BACKENDS

Add support for filtering out possible compilers by their backend,
on top of the frontend version filtering already implemented.
This allows packages that do not support a particular compiler backend
not to advertise USE flags that will fail to build.

dlang.eclass: export PKG_CONFIG_* in phase functions

PKG_CONFIG_LIBDIR and PKG_CONFIG_PATH will now be set to a list of the
the system pkg-config directories and the compiler specific one, allowing
packages that use build systems to easily find both their C and D
dependencies.

dlang.eclass: Properly set LIBDIR_$ABI for single type packages

Previously, only packages that set DLANG_PACKAGE_TYPE to multi
received a valid value in LIBDIR_$ABI, the path to the compiler
specific directory for libraries, in order to know where to
install their libraries.

Now, both types of packages will have this value set properly,
alowing single type packages to know the exact path to the
compiler library directory for easy access to auxiliary files
like pkg-config files.

dmd.eclass: explicitly specify arguments to dmd in tests

Refactor the test code a little for better readability and prevent
linking by default to libphosbos2.a, which happens to work only because
the build wrongfully generates both shared and static libraries
regardless of USE=static-libs.

Pass the same options to dmd as the ones in the installed dmd.conf to
get a closer setup to what the user will have installed on their system.

+# @BLURB: A common eclass for Dlang packages.
+# @DESCRIPTION:
+# A common eclass providing helper functions to build and install
+# packages supporting being installed for multiple Dlang implementations.
+#
+# This eclass sets correct IUSE. Modification of REQUIRED_USE has to
+# be done by the author of the ebuild (but DLANG_REQUIRED_USE is
+# provided for convenience, see below). dlang-r1 exports DLANG_DEPS
+# and DLANG_USEDEP so you can create correct dependencies for your
+# package easily. It also provides methods to easily run a command for
+# each enabled Dlang implementation and duplicate the sources for them.
+#
+# Please note that dlang-r1 will always inherit dlang-utils as
+# well. Thus, all the functions defined there can be used
+# in the packages using dlang-r1, and there is no need ever to inherit
+# both.
+#
+# There is one more particularity about the eclass. In order to provide
+# correct DLANG_DEPS and DLANG_REQUIRED_USE the contents of KEYWORDS
+# need to be set before the inherit, see the example below.
+#
+# @EXAMPLE:
+# @CODE
+# EAPI=8
+# DLANG_COMPAT=( dmd-2_{101..106} gdc-12 gdc-13 ldc2-1_{32..36} )
+# KEYWORDS="amd64 x86"

+# which package will be built for. It needs to be specified in the
+# calling environment, and not in ebuilds.
+#
+# It should be noted that in order to preserve metadata immutability,
+# DLANG_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
+# The state of DLANG_TARGETS is ignored, and all the implementations
+# in DLANG_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
+# manually.
+#
+# Example:
+# @CODE
+# DLANG_COMPAT_OVERRIDE='gdc-13 dmd-2_106' emerge -1v dev-libs/foo
+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_REQ_USE
+# @DEFAULT_UNSET
+# @PRE_INHERIT
+# @DESCRIPTION:
+# An associative array of Dlang implementations and USE-dependencies
+# strings. The keys are implementation names, so: "dmd" "ldc2" or "gdc";
+# and the values are the aforementioned USE-dependency strings.
+#
+# This should be set before calling `inherit'.
+#
+# Example:
+# @CODE
+# declare -A DLANG_REQ_USE=(
+#     [dmd]="static-libs(-)?"
+#     [gdc]="another_flag"
+#     [ldc2]="static-libs(-)?"
+# )
+# @CODE
+#
+# It will cause the Dlang dependencies to look like:
+# @CODE
+# dlang_targets_ldc2-X_Y? ( dev-lang/ldc2:X.Y=[static-libs(-)?] )
+# dlang_targets_gdc-X? ( sys-devel/gcc[d,another_flag]:X dev-util/gdmd:X )

+# @CODE
+
+# @ECLASS_VARIABLE: BUILD_DIR
+# @OUTPUT_VARIABLE
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# The current build directory. In global scope, it is supposed to
+# contain an initial build directory; if unset, it defaults to ${S}.
+#
+# In functions run by dlang_foreach_impl(), the BUILD_DIR is locally
+# set to an implementation-specific build directory. That path is
+# created through appending a hyphen and the implementation name
+# to the final component of the initial BUILD_DIR.
+#
+# Example value:
+# @CODE
+# ${WORKDIR}/foo-1.3-ldc2-1_35
+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_DEPS
+# @OUTPUT_VARIABLE
+# @DESCRIPTION:
+# This is an eclass-generated Dlang dependency string for all
+# implementations listed in DLANG_COMPAT.
+#
+# Example use:
+# @CODE
+# RDEPEND="${DLANG_DEPS}
+#	dev-foo/mydep"

+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_USEDEP
+# @OUTPUT_VARIABLE
+# @DESCRIPTION:
+# This is an eclass-generated USE-dependency string which can be used to
+# depend on another Dlang package being built for the same Dlang
+# implementations.
+#
+# Example use:
+# @CODE
+# RDEPEND="dev-libs/foo[${DLANG_USEDEP}]"

+# @BUGREPORTS:
+# Please report bugs via https://github.com/gentoo/dlang/issues
+# @VCSURL: https://github.com/gentoo/dlang
+# @SUPPORTED_EAPIS: 8
+# @PROVIDES: dlang-utils
+# @BLURB: An eclass for Dlang packages not installed for multiple implementations.
+# @DESCRIPTION:
+# An extension of the dlang-r1 eclass suite for packages which don't
+# support being installed for multiple Dlang implementations.
+#
+# This eclass sets correct IUSE. It also provides DLANG_DEPS and
+# DLANG_REQUIRED_USE that need to be added to appropriate ebuild
+# metadata variables.
+#
+# The eclass exports DLANG_SINGLE_USEDEP that is suitable for depending
+# on other packages using the eclass.  Dependencies on packages using
+# dlang-r1 should be created via dlang_gen_cond_dep() function, using
+# DLANG_USEDEP placeholder.
+#
+# Please note that packages which support multiple Dlang implementations
+# (using dlang-r1 eclass) can not depend on packages not supporting them
+# (using this eclass).
+#
+# Please note that dlang-single will always inherit dlang-utils as
+# well. Thus, all the functions defined there can be used in the
+# packages using dlang-single, and there is no need ever to inherit
+# both.
+#
+# Same as dlang-r1.eclass, the contents of $KEYWORDS need to be set
+# before the inherit.
+#
+# @EXAMPLE:
+# @CODE
+# EAPI=8
+# DLANG_COMPAT=( dmd-2_{101..106} gdc-12 gdc-13 ldc2-1_{32..36} )
+# KEYWORDS="amd64 x86"
+#
+# inherit dlang-single
+#
+# REQUIRED_USE=${DLANG_REQUIRED_USE}
+# DEPEND="${DLANG_DEPS} $(dlang_gen_cond_dep '
+#     dev-libs/gtkd[${DLANG_USEDEP}]
+# ')"
+# RDEPEND=${DEPEND}
+# BDEPEND=${DLANG_DEPS}
+#
+# src_compile() {
+#     emake DMD="$(dlang_get_dmdw)" DFLAGS="$(dlang_get_dmdw_dcflags)"

+# @ECLASS_VARIABLE: DLANG_COMPAT
+# @REQUIRED
+# @PRE_INHERIT
+# @DESCRIPTION:
+# This variable contains a list of Dlang implementations the package
+# supports. It must be set before the `inherit' call. It has to be an
+# array.
+#
+# Example:
+# @CODE
+# DLANG_COMPAT=( gdc-12 ldc2-1_36 dmd-2_102 dmd-2_103 )
+# @CODE
+#
+# Please note that you can also use bash brace expansion if you like:
+# @CODE
+# DLANG_COMPAT=( gdc-1{2..3} ldc2-1_{29..36} dmd-2_10{5,6} )
+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_COMPAT_OVERRIDE
+# @USER_VARIABLE
+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# This variable can be used when working with ebuilds to override the
+# in-ebuild DLANG_COMPAT. It is a string naming the implementation which
+# package will be built for. It needs to be specified in the calling
+# environment, and not in ebuilds.
+#
+# It should be noted that in order to preserve metadata immutability,
+# DLANG_COMPAT_OVERRIDE does not affect IUSE nor dependencies. The state
+# of DLANG_TARGETS is ignored, and all the implementations in
+# DLANG_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
+# manually.
+#
+# Example:
+# @CODE
+# DLANG_COMPAT_OVERRIDE='gdc-13' emerge -1v dev-libs/foo
+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_REQ_USE
+# @DEFAULT_UNSET
+# @PRE_INHERIT
+# @DESCRIPTION:
+# An associative array of Dlang implementations and USE-dependencies
+# strings. The keys are implementation names, so: "dmd" "ldc2" or "gdc";
+# and the values are the aforementioned USE-dependency strings.
+#
+# This should be set before calling `inherit'.
+#
+# Example:
+# @CODE
+# declare -A DLANG_REQ_USE=(
+#     [dmd]="static-libs(-)?"
+#     [gdc]="another_flag"
+#     [ldc2]="static-libs(-)?"
+# )
+# @CODE
+#
+# It will cause the Dlang dependencies to look like:
+# @CODE
+# dlang_targets_ldc2-X_Y? ( dev-lang/ldc2:X.Y=[static-libs(-)?] )
+# dlang_targets_gdc-X? ( sys-devel/gcc[d,another_flag]:X dev-util/gdmd:X )

+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_DEPS
+# @OUTPUT_VARIABLE
+# @DESCRIPTION:
+# This is an eclass-generated Dlang dependency string for all
+# implementations listed in DLANG_COMPAT.
+#
+# Example use:
+# @CODE
+# RDEPEND="${DLANG_DEPS}
+#	dev-foo/mydep"

+# @CODE
+
+# @ECLASS_VARIABLE: DLANG_SINGLE_USEDEP
+# @OUTPUT_VARIABLE
+# @DESCRIPTION:
+# This is an eclass-generated USE-dependency string which can be used to
+# depend on another dlang-single package being built for the same Dlang
+# implementation.
+#
+# If you need to depend on a multi-impl (dlang-r1) package, use
+# dlang_gen_cond_dep with DLANG_USEDEP placeholder instead.
+#
+# Example use:
+# @CODE

dmd-r1.eclass: clarify dependency on stdlib of host compiler

The previous comment, saying that dmd doesn't link the standard lib of
the host compiler, is plain wrong, it always does. The only
particularity is that dmd doesn't seem to need phobos but it does need
druntime. Regardless, a RDEPEND on the host compiler is needed.

Another comment has been added trying to describe the reason why
DLANG_DEPS should be present in DEPEND. My current understanding is that
since the compiler needs to link libraries from SYSROOT (druntime and
phobos) to produce the CHOST dmd executable then those libraries should
be listed in DEPEND. I'm not 100% sure though.

dlang-compilers-r1.eclass: Correct ldc2:1.39 entry to match ebuild

Correct the keywords list in the eclass by removing the arm64 keyword
which has been dropped with the ldc2:1.39 addition. It should be added
back when tests on arm64 can be performed again.

+# @CODE

+# perform a fetch operation, perhaps as part of tests, in all other
+# cases DUB_DEPENDENCIES should be used instead.
+#
+# You can use dub_copy_dependencies_locally as a convenience function.
+#
+# Example:
+# @CODE
+# src_unpack() {
+#   dub_src_unpack
+#   use test && dub_copy_dependencies_locally "my_packages@1.1.0"
+# }
+# src_test() {
+#   dub_src_test
+#
+#   # additional test that performs `dub fetch my_package@1.1.0`
+# }
