vibe.d 0.8.0 and 0.7.31 beta releases

[Sönke Ludwig via Digitalmars-d-announce]

The first release of the revamped core module [1] is nearing, and along 
with that, a compatible vibe.d release (0.8.0). The new core module is 
still opt-in in this release and can be activated using a 
`subConfiguration "vibe-d:core" "vibe-core"` directive in dub.sdl 
(`"subConfigurations": {"vibe-d:core": "vibe-core"}` in dub.json).

In parallel to the 0.8.x branch, the 0.7.x branch will stay maintained 
for a while, but the 0.7.31 release will be the last one to contain new 
features. For anyone who does not depend on old D frontends, it is 
strongly recommended to switch to the 0.8.x branch as soon as possible 
and also to test with vibe-core (production deployments are safer off 
staying with the old :core module for now), as the transition period is 
supposed to be only as long as necessary to guarantee a stable 
implementation.

To give an overview, here is the list of the biggest changes:

- The whole library is now split into fully separate sub packages. This
   required some code changes, because there were some hidden circular
   dependencies between modules. Some parts have also been moved to the
   new sub packages "stream", "textfilter", "crypto" and "inet".

- Large parts of the API are now annotated with nothrow and @safe. In
   case of APIs that depend on callbacks, these can be breaking changes,
   but the most prominent places have deprecation paths in place.

- The vibe-d:core sub module has got a new configuration "vibe-core"
   that causes it to be replaced by the vibe-core package.

- The stream API has been made forward compatible with vibe-core. This
   adds optional IOMode parameters to the read/write methods (the value
   is currently ignored) and deprecates the leastSize and
   dataAvailableForRead properties.
