This typedef can be used by plugins that don't want to hard-code the
type of the Mumble API type (which contains the API's version) into
their source code.
If this typedef is used, a newer API can be used simply by including a
different API header.
There were a few types left that were not prefixed with "Mumble" in one
way or another. In order to avoid name clashes, this was now changed.
Especially enum values are now also prefixed. This is because these are
not enum classes (C doesn't know those) and as such the enum values are
used without a namespace (thus they are effectively global names).
Furthermore the macros STATUS_OK and VERSION_UNKNOWN were turned into
constant variables in order to use the preprocessor as little as
possible.
This commit introduces a new plugin framework into the codebase of the
Mumble client. Note that "plugin" here really refers to a (more or less)
general purpose plugin and is therefore not to be confused with the
previously available positional data plugins (only responsible for
fetching positional data from a running game and passing that to
Mumble).
The plugin interface is written in C, removing the compiler-dependence
the old "plugins" had. Instead plugins can now be written in an
arbitrary language as long as that language is capable of being compiled
into a shared library and also being capable of being C-compatible.
As already indicated a plugin is essentially a shared library that
provides certain functions that allow Mumble to interface with it.
Inside Mumble the so-called PluginManager is responsible for managing
the plugins and relaying events to the respective callbacks. Plugins
themselves can also interact with Mumble on their own initiative by
using the provided API functions.
