* include/lightning.h, lib/lightning.c: Implement the new
jit_clear_state and jit_destroy_state calls. jit_clear_state
releases all memory not required during jit_execution; that
is, leaves only the mmap'ed data and code buffers allocated.
jit_destroy_state releases the mmap'ed buffers as well as
the jit_state_t object itself, that holds pointers to the
code and data buffers, as well as annotation pointers (for
disassembly or backtrace) in the data buffer.
* lib/jit_note.c: Correct invalid vector offset access.
* check/ccall.c, check/lightning.c, doc/ifib.c, doc/incr.c,
doc/printf.c, doc/rfib.c, doc/rpn.c: Use the new jit_clear_state
and jit_destroy_state calls, to demonstrate the new code to
release all jit memory.
* doc/body.texi: Add basic documentation and usage description
of jit_clear_state and jit_destroy_state.
* check/Makefile.am: "make debug" target should pass only
the main test tool program as argument for running gdb
* configure.ac: Add the --enable-assertions options.
* doc/Makefile.am, doc/body.texi, doc/lightning.texi:
Major rewrite of the documentation to match the current
implementation.
* doc/version.texi: Automatic date update.
* doc/ifib.c, doc/incr.c, doc/printf.c, doc/rfib.c, doc/rpn.c:
Implementation of the documentation examples, that are also
compiled during a normal build.
* doc/p-lightning.texi, doc/porting.texi, doc/toc.texi,
doc/u-lightning.texi, doc/using.texi: These files were
renamed in the documentation rewrite, as the documentation
was significantly trimmed due to full removal of the porting
chapters. Better porting documentation should be added but
for the moment it was just removed the documentation not
matching the implementation.
