Add .def files to the list of source file types to pass to the linker.

Implement separate linking on gdc

Fix output flags for compilers != dmd

Add an explanation message for exit code -9. ...

This is a common enough issue to warrant a little diagnostic assistance (the compiler/linker process getting KILLed by the kernel due to out-of-memory).

Make prepareBuildSettings, extractBuildOptions and setTarget const

Use executeShell() to invoke the compiler. See #356. ...

execute() doesn't support running scripts with shebang lines. Still needs to be actually tested with a script on Linux/OS X.

Output all possible source/import files for "dub describe". Fixes #185. ...

Files that are not used for the current configuration or platform are output with an "unused" prefix (e.g. "unusedSource").

Use tabs in all JSON and D files

Removed trailing whitespace

Use "dub.json" instead of "package.json" in documentation

Ignore any noise on stdout when reading back the platform information.

Fix suggestion text for -debug= dflags. See #310.

Remove debug log noise.

Put BuildSettings into its own module and invoke DMD to determine the actual build platform. ...

Currently only for DMD, the build platform is now determined by actually invoking the compiler with the proper -mX switches instead of guessing from the compiler run that was used to build DUB.

Improve diagnostic messages for pkg-config.

Only pass known libraries to pkg-config. Fixes #274. ...

This is yet untested. Also disables calling pkg-config on non-Posix systems.

Missing tilde

Merge branch 'dustmite'

Also warn about using certain "buildOptions" in addition to "dflags".

Warn when using -m32/-m64 directly.

Add support for execution result callbacks in the build generator.

Avoid using the deprecated canFind function.

Implement individual building of dependencies.

Rename BuildOptions.noBoundsChecks to noBoundsCheck to be consistent with BuildRequirements.requireBoundsCheck.

Enforce build requirements when generating VisualD projects. Fixes #188.

Rename some BuildOptions to avoid D keywords.

Add support for a "mainSourceFile" field. ...

The main source file is used as the root to access the whole package. This is important for dependency based building, such as with RDMD and for special build kinds, such as for a future unit test command. This also improves the robustness of "dub build --rdmd".

Main source files are automatically inferred as follows, if not explicitly given:
 1. search first in "source/", followed by "src/"
 2. take the first match of ("app.d", "main.d", "<pkgname>/main.d", "<pkgname>/<pkgname.d>") as the main file for the automatic "application" configuration
 3. take the first match of ("<pkgname>/all.d", "<pkgname>/package.d", "<pkgname>/<pkgname>.d") as the main file for the automatic "library" configuration

Import and string import files are now added to generated VisualD projects and "dub describe".

Support excluding paths using glob matching.

Remove dub.internal.std.process compatibility code as it doesn't support browse() and the compile status on older DMD versions isn't tracked anyway.
