* include/lightning/jit_private.h, lib/jit_note.c, lib/lightning.c:
Store all annotation information in the mmap'ed area reserved for
read only data. This adds code to not allocate memory for jit_note_t
objects, and to relocate jit_line_t objects and its contents after
calculating annotation information. The jit_line_t objects are
relocated because it is not possible to always calculate before
hand data layout because note information may be extended or
redundant entries removed, as well as allowed to be added in
non sequential order.
A bug was also corrected in _jit_set_note, that was causing it
to allocate new jit_line_t objects when not needed. It was still
working correctly, but allocating way more memory than required.

lib/jit_x86.c, lib/lightning.c: Extend the "jit_note" abstraction
with the new "jit_name" call, that receives a string argument, and
should usually be called to mark boundaries of functions of code
generating jit (that is, it is not expected that the language
generating jit map its functions to jit functions).
* lib/jit_note.c: New file implementing a simple string+integer
annotation, that should be used to map filename and line number
to offsets in the generated jit.
* include/lightning.h, lib/lightning.c: Update for the new
note code.
Add an extra mandatory argument to init_jit, that is used
as argument to bfd_openr.
Change from generic void* to char* the argument to jit_note
and add an extra integer argument, to map to filename and
line number.

automake.
