Rename README to README.md
Rename LICENSE to LICENSE.md
Rename HACKING to HACKING.md
make rt_init/rt_term callable from C

- deprecate the ExceptionHandler in Runtime.initialize/terminate

- declare/document rt_init/rt_term in core.runtime
keep track about how often rt_init/rt_term were called

- This is necessary because a C program might
  initialize multiple D libraries, of which
  each has to call rt_init/rt_term in their own
  init/term functions.
make runtime initialization/finalization explicit

- fix Issue 11378 - implicit runtime initialization/finalization
  is broken

- C programs need to call rt_init in order
  to initialize the runtime and all shared
  libraries.

- After rt_init was called shared libraries are
  initialized on loading and finalized on unloading.

- C programs need to call rt_term in order
  to finalize the runtime and all shared
  libraries.

regression test for Issue 10701

- The test isn't 100% reliable because it depends
  on the GC and array append cache state.
