Make getDUBExePath returns a NativePath

make build names much smaller (#2589)

fix typo(s)

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

reduce dependency on the working directory ...

Improves library API usage and bugs with the build generator

Don't assume the cache path is relative to CWD ...

It is no longer in `$PACKAGE_ROOT/.dub`, but in a central location.

Remove GeneratorSettings.direct as it is never set

Use a central build cache for all build artifacts ...

Currently the central build cache is not configurable,
but as most build artifacts end up in `~/.dub/packages/` anyway,
this will be a positive change for users.

Move computeBuildID outside of BuildGenerator ...

It does not use anything from 'this', only its input parameters.
Additionally, change the order so it is usable with UFCS.

Replace all instances of mkdirRecurse with ensureDir ...

All usages actually want to ensure the directory is present,
and don't care about having a separation between existence check
and creation.

Unify reading and writing files under a single API ...

This removes the range API and instead uses Appender,
while using a limited and centralized set of functions
to read/write from files.
The end goal is to permit dependency injection,
which is a pre-requisite to extending the test-suite.

Copy all dynamicLib deps extra files for root packages with `none` targetType ...

To support 'framework' use cases - a dummy root package depending on a bunch
of dynamicLibs, where all extra files are to be copied to the output dir.

Copy extra files of (direct & indirect) dynamicLibrary deps to root package output dir only

Windows: Copy .lib files from DLL deps only ...

One aspect of issue #2377 - don't copy static libs. And only copy
import .lib & .exp if the dependee is a DLL too.

Support --temp-build also in `dub build` (#2428)

Integrate `dependencyBuildSettings` into dependencies ...

Because those are specified in `dependencies`,
they should be stored alongside them.
Unfortunately this will slihtly increase memory usage in the common case,
but unlikely to a point where it would be problematic.

This is technically a breaking change as a field is getting removed,
however this struct has been manipulated a few times in breaking ways,
and it's unlikely `dependencyBuildSettings` is being used outside of dub,
given how recent it is and how narrow its usage is.
However, as `dependencies` is likely to be widely used, a compatibility
type and an `alias this` are provided not to break client code.

Windows: Don't copy import .lib & .exp files for executables ...

One aspect of issue #2377 - copy those for DLLs only.

Avoid calls to .dup in cmake.d (#2421)

Forward flag `--color={on,off}` to compiler calls (#2382) ...

When the user sets the color mode explicitly,
we forward it to the compiler for consistency,
while making sure it doesn't impact the build cache ID.

Fix #2348 Crash when describing postBuildCommands

Recursively link all link deps of dynamic libraries too (#2414) ...

Templates exposed by a dynamic library A can easily lead to
instantiations in dependees needing to be linked against a direct or
indirect dependency of A.

Use SHA256 in place of MD5 in computeBuildName

Minor: Replace a foreach with a nested function ...

Avoid an allocation every time and a cast.

improve some output coloring ...

See #2347

Keep logging functionality out of the public API as requested in https://github.com/dlang/dub/pull/2124#issuecomment-813016939.

Fix/Update some tests and make some info messages more similar to original version of Dub

Fix indentation style, now using tabs

Fixed blue color missing for config in up-to-date

More improvements and replacements ...

Adapted generators output to new style, small change for non-selected
packages
