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. Fixes #2455 Fixes #2148 Fixes #1594 Fixes #2051 Fixes #3742 Fixes #4575 Fixes #4751
