Feature to enable asynchronous event driven of network events

Improve callback mechanism to allow an arbitrary userData pointer to be passed during callback registration that will subsequently be passed to the callback
Improve error handling on getsockopt when a level other than SOL_SOCKET or an optname other than SO_ERROR is supplied as per the conversation with juj
Make debug message for the default logging on error handler use Module.printErr rather than Module.print as suggested by juj
Add some more documentation to emscripten.h to explain that the JavaScript error callback takes an array containing the file descriptor, error code and error message.
Modify server on error to be consistent with the client on error
fix the build failures (we should only delete the jcache directory, not everything)
Add missing libc files to the build.
add pkg-config files for some supported libraries
clang 3.4.2 complains about weak_alias for a symbol that isn't defined

Let -s RELOOPER work correctly.
Exit from src/compiler.js with a nonzero return code on exception. Replaces #2453.
Remove ".dll" from DYNAMICLIB_ENDINGS, since on Windows one never links to a .dll file directly (e.g. via a command line -lFile -> libFile.dll) either, but instead separate import libraries with suffix .lib are used. Note that for crosscompiling, it is _not_ recommended to generate Emscripten static bitcode libraries with suffix .lib, but instead generating files with suffixes .bc (or .a) is better form.
Add vim temp files to .gitignore
