Don’t call writeln in generated code when measuring coverage and indent generated code

Add support for coverage at compile-time (CTFE)

Adding known test case for #2258

Support special test runner configuration for `dub describe` as well

Fix #1856 - enable building the special test runner config

Ugh test needed .no_test not changing from being a main function

Okay, tests wants unittests not main functions, righto

Fix injected-from-dependency test

Fix injectSourceFiles not going into description or actually working

Implement injection of source files from dependencies into parent final binaries (executed/shared libraries)

Adapt determinePlatform to the new defaults for Win32 ...

Starting with DMD 2.099, `-m32` defaults to MsCOFF instead of OMF and
`-m32omf` is required to use the OMF format + OPTLINK.

This commit changes the logic to select the appropriate logic based
on the current compiler version. Potentially using the wrong object file
format during platform probing is fine because the codegen is skipped
(dmd is invoked with `-c -o-`).

fix: parse version from filesystem supplier correctly

Fix interactive run-unittest.d ...

When providing arguments to run-unittest.d it would use them to determine which files to run. This change makes it, so that it doesn't try to run the arguments both as .d and as .sh files.

substitute commands in dub describe output

move command variable substitution to execution ...

This is needed as commands that need to be run need to have generator
settings available before running to avoid inconsistencies with
environment variables passed to the actually ran program and variables
used in substitution.

Fixes #2192

Fixes pre/postGenerateCommands inconsistently using dub environments
(execution was substituted including buildEnvironments, but shell cmd
did not get the build variables for substitution) - now both get
the build variables. Solved by removing code duplication. (env building)

This commit changes the behavior of `dub describe` so that describing
commands settings no longer substitutes variables. Before, known
variables would have been replaced in the output and on unknown
variables `dub describe` would fail with an error
`Target 'x' doesn't exist`

Now exposes some previously private project.d processVars functions

Removes dynamicLibrary being built as staticLibrary for targets other than OMF

Fix issue 2051 failing CI

Fix build setting inheritance ...

First inherit upward then force the dependency build settings
downwards. Fixes the dependency build settings leaking upwards.

Fixes #2176
Fixes #2177

fix Issue 1645: the DFLAGS env variable is not handled when --build is passed

Generate paths relative to visuald project files (#2150) ...

Fixes #1477 : Internal paths for sources etc in projects should be relative to project file path. Actually relative to "working dir"/.dub

Add environment variables to BuildSettings (#2121)

Merge remote-tracking branch 'upstream/stable' into merge_stable

fixed a bug with DFLAGS environment variable and cached generated unittest

Merge pull request #2109 from drug007/replacing-rununittest.sh ...

Replacing rununittest.sh

Convert one bash script test to D script

Run d scripts ...

run-unittest.d runs files in `test` subdir with "*.script.d" extension

Fix the path to the binary
