Add betterC probing for performance and for applications without drun… (#2753) ...

* Add betterC probing for performance and for applications without druntime
* Build probe pragmas using a pragmaGen function rather than string duplication.
* Add some formatting adjustments

Move dmd version parser to packagerecipe ...

This module is the only one that uses it, so instead of having
it in a place that looks correct but where it is not used,
move it to packagerecipe and make it private.

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.

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.

Posix: Add default SONAME/install_name for dynamic libraries ...

Setting it to the filename (ELF) or `@rpath/<file name>` (Mach-O).

This seems to be required in order to use the libraries copied to
the output directory of dependees - either by setting the
LD_LIBRARY_PATH env var when starting the executable, or baking a
RUNPATH into the executable (e.g., via `patchelf --set-rpath` for
deployment).

Otherwise the loader tries to load the library from the original
location specified in the linking cmdline, which is some
`<path to dep pkg>/.dub/…` path (and apparently potentially
relative, and thus even more brittle). For ELF, I would assume
that all SONAME + DT_NEEDED entries (of executable + all .so libs)
would need to be post-processed to enable loading the libs from the
executable's directory (well, any non-original location).

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

New logging module - initial functionality ...

The new module replaces dub.internal.vibecompat.core.log by using the
same function names, but implementing colored output and the left
fixed-width tag. Overloaded functions are provided to output colored
text.

Still missing initLogging() and non-TTY stdout/stderr detection

Build{Options,Requirements}: Use a common templated struct ...

A bit less copy-pasta is a small but appreciable win.

Merge pull request #2259 from rikkimax/fix-issue2258 ...

Refactor checks for platform is Windows into a method on BuildPlatform

Add support for coverage at compile-time (CTFE)

Add export (.exp) files to isDynamicLibraryFile for full Windows support when copying build artifacts

Fix issue 2258 and copy the build artifacts to the target directory

Replace occurences of 'in ref' with 'const scope ref' ...

In support for dlang/dmd#11000

reduce visual complexity of concatenation with std.string.fromat

Print the platform probe atomically ...

DMD may print some stuff in between call of `pragma(msg)` and corrupt the json data.

Improve cross-compilation support (replace `version` checks by BuildPlatform runtime checks) ...

Also fixes #1249. For LDC as implicit cross compiler, the file
extensions for libraries and object files etc. don't depend on the
compiler, but solely on the target. Targets selected with `--arch` are
correctly probed by dub, so that the parsed `BuildPlatform` represents
the target platform.

Change toolchainRequirements fields to Dependency. ...

Also removes some API clutter from Compiler and PackageRecipe.

toolchainRequirements recipe support

Add build type syntax

dub.compilers.utils: Fix platform probe code when nothing is detected ...

If determinePlatform / determineArchitecture return an empty
array (due to Dub not knowing about the target platform), the probe
file crashed during compilation due to attempting to index an array
at position 0.

Fix this by using a less unnecessarily-generic function to concatenate
elements of a JSON array.

speed up platform probe 50ms -> 5ms by avoiding phobos imports

Rename Path to NativePath. ...

Matches the changes done in vibe.d 0.8.x and vibe-core.

Refactor determinePlatform, determineArchitecture, and determineCompiler from dub.platform into strings that can be pasted into generatePlatformProbeFile and remove unused imports.

Add example for architecture flag usage warning.

spelling fixes

Merge branch 'stable'

introduce x86-mscoff arch

Fix deprecation warning on Windows.

Eliminate use of Json.opDispatch. ...
